Stupidity Is Not A Great Consulting Skill


Most companies don’t get that body shopping and contracting is not consulting. And today way too many consultants don’t match up to the requirements of being one. So basically these people pay way too much for too little. I have no mercy for fake consultants and companies so messed up in their political crap they fail to recognize quality and value. Just read The do’s and don’ts when engaging consultants Part I and The do’s and don’ts when engaging consultants Part II where I’ve given some rules of fist for optimizing the use of consultants. But here’s some advice to fake consultants. At least try to act professional and be nice. Because one on the main rules of long term happiness while staying employed is the fact that people not want to work with a*holes.

  • Don’t download or synchronize hacking tools while at your employer/customer.
  • If you’re an IT Pro or developer  and you cannot figure out how to expand or mount an ISO with the tools on a modern PC/OS you should realize they want to fire you on the spot for gross incompetence.
  • Playing games like a long term frustrated employee with help desk personnel regarding mundane tasks and leveraging policies or rules as excused not to get work done is annoying, immature & frowned upon.
  • Waiting until you get asked why you didn’t get work done to mention your PC got confiscated due to a security incident an the replacement was missing a tool proves you’re a dead weight.
  • Churning is nothing short of fraud. You deliver real work or get out.
  • It’s rather easy to see that the hours you telecommute are not matching your time sheets. It gets noted. At best they’ll pull a Yahoo on you.
  • When you state that optimizing parallelism in SQL Server and using multiple LUNs and data files is waste of time in an environment that’s on the record for being in the top 5 SQL server operations in the country you might perhaps realize you are being an a* hole. Yes it requires some work, the database is not designed to cater to your laziness, but for performance.
  • It’s designed and build at a great value point by skilled people who earn mediocre wages but are very good and love what they do. Do you even realize the level of your arrogance and the fact that you are now on the “do not hire list”?
  • Realize that not all people who’re working as an employee are clueless sheep that only serve to line your pockets. Most of them are good. Many of of them are great, some even excellent to exceptional. Even when not subject matter experts they’ll see through any fake expertise.

Look, when you’re dead, you don’t realize that, so for you there is no drawback, it’s all good. It’s your surroundings that notice it and have to deal with the loss, the pain. It’s the same when you are stupid. It’s the people around you that suffer. Get it?

Technical Projects, Planning, Skills, Motivation & Psychopaths


When planning a technical project complexity adds ups very fast. Take a virtualization project for example; a lot more things than just the hyper visor installation are coming into play. You’ll need to asses a lot of needs and desires about SANs (snapshots, redundancy, replication, FC, iSCSI, FCoE), network (VLAN, 1/10 Gbps Ethernet, redundancy), disaster recovery/business continuity, hyper visors and there capabilities, management of it all and security. That is a lot of stakes and agendas to take into consideration. And then you haven’t even talked to the business managers, the application owners and developers. Now this isn’t limited to virtualization, but this is just a nice example on how so many stakes come together in one project.

One of the major mistakes, that is made again and again even up until this day in the second decade in the 21st century is the fact that entire important or even critical IT systems are being put into place with a plan that can be paraphrased as follows “We’ll just set it up and sort of see how it evolves and just wing it from there”. I have been forced to do this quite often. This creates many problems some of which I will address below.

The single worst problem is that you create a vacuum. That can be storage space, bandwidth, ample resources for a huge amount of virtual machines or a mixture of all this. The results however are always the same and is one of two possibilities. Either they really don’t want and need it so it will never be used. You can also achieve this by keeping it hidden so they can’t use it. The other option is the most natural one. In nature there is a thing called a “horror vacui”. That means that a vacuum unless protected cannot exist, it has to be filled. Empty LUNSs with data, hyper visor hosts with guest, networks with bandwidth and backup capacity with even more terabytes. You might think the second option is better than the first one as at least the infrastructure is getting used. Unfortunately the reality is that this is creating a very expensive mess to run, support & troubleshoot. The legacy this creates is not a valuable inheritance but a bank breaking, efficiency and effectiveness ruining debt. Stop doing that right now, you are killing your business. You see technology debt is about more than just old hardware and software. It’s about what you build with it or what grows organically with it. Is that a fertile land that sustains the business or a cancer that is killing it?

The way to prevent this is planning done by competent, involved people with experience and context. No plan is perfect, but a plan gives you a framework to achieve the desired result. Even great people make mistakes but they have the skills and attitude to fix them or work around them.

What are some other problems? Wasting money. Take for example a completely oversized server farm. That thing will consume so much money over a three year period in energy and idle capacity that the amount would be sufficient to replace it with new right sized hardware (more bang for the buck, better energy efficiencies in three years) I don’t know about you but those are very disconcerting numbers.

You can also be wasting money and time. And those who know me I loath wasting time. What if the SAN solution you bought doesn’t perform as planned or isn’t the right fit? There goes 500.000 € or you find yourself in the CEO office explaining why you need an extra 400.000 € to get what is really needed. Oh oh! Do you have money and time to do it all over again or will you be living with that expensive mistake until the current solution is end of life? Do you have to wait until the CFO and CEO have recovered enough from the shock to allow a new attempt? Or perhaps you bought a SAN solution that is enough to run NASA’s workload and you’ve invested 4.000.000 € in a rather expensive data room heater.

Getting a virtualization project wrong can wreak havoc on a business and create a sizable financial hemorrhage. You can say that that’s not your problem but I beg to differ. If the project goes south that means you’ll have to find another job. The IT world where I live is rather small so you might even have to switch to another field as you’ll be forever known as the guy that sunk company X with his little “plan”.

The reverse, being rewarded for your hard work and success is not a given. In the end they pay you for getting the job done so results are expected, and to Joe Average manager all ICT is a PC with a software packet to install. So for all you eager beavers who think that with this kind of responsibility and risk management comes big reward when you get it right I suggest you think again. I have witnessed quite the opposite personally. Even when you’re running multiple enterprise SAN’s, networks, infrastructures like SQL Server, Exchange clusters, Hyper-V clusters, geo clusters, load balancers and providing 2nd and 3rd line support for those and taking 24/7 responsibility for the environment the only thing some managers care about is why the PC they never ordered with the software they never ordered can’t be installed tomorrow. “What kind of a chicken shit outfit are you running here” is what they’ll think when you can’t do that. They’ve read the glossy brochure that IT is a commodity and they expect it cheap and always on, much like electricity. In the end some (incompetent) managers act like ungrateful psychopaths. They’ll just abuse you less when you get it right. Don’t expect anything else. Often it’s the ones that are not capable to integrate things they can’t do or don’t understand into their business. They can not value anything that’s beyond their comprehension so they’ll never recognize it. To them, people are, for all practical purposes, resources that are identical, “Full Time Equivalents”. So don’t buy into the hype that there is a skills shortage from that lot and they can’t fill job openings. The volume in which they often waste talent and flush motivation down the drain is shockingly high and indicates that there is no shortage at all or that they can’t recognize skills when they find it and they’ll hire anyone. Surely they didn’t make a mistake so it must be a skills shortage. So you still want to be some hot shot technical architect? Or does a job that only produces open opinions and optional advice on paper sound more attractive. Per hour worked you’ll earn more, run less risk and have a lot less stress. My advice? Don’t switch fields if you enjoy what you’re doing, switch jobs. The best career advice I ever got was “don’t work with or for assholes”.

Well if you don’t agree with your bosses and you dare go against them you’re surely playing with your job, you could get fired! So? Does living in fear of being fired make good employees? Does not being strong and confident enough to tell your managers they are doing certain things totally wrong or that they are mistaken make for good advisors? The worst thing a boss can have are a bunch of “yes men” around him or her. That boss should be smarter than that. It doesn’t work. Having trust in the abilities and loyalty of your employees does not mean you need to agree on everything. As a boss you’ll make the final decisions, yes, but you’d better listen very carefully to your advisors and staff or you might as well have hired some monkeys. You can train them to say yes all the time, all it takes are some bananas. As an employee, don’t let yourself be treated like a monkey and if they fire you for throwing the banana back, good for you!

So you’d better love technology and building solutions because that means you are intrinsically motivated to go the extra miles. When you are, select a small group of people with the same attitude. You’ll be able to drag the devil himself out of hell with such a team at relatively very low cost. Whatever you, do don’t think you can externally motivate or coerce people into achieving this. Charles “Chargin’ Charlie” Beckwith knew that all along when he said “I’d rather go down the river with seven studs than with a hundred shitheads”. And guess what, he wasn’t taught this in some course, by getting a title or by being told this by a manager. He learned it himself by working with the best. These people will keep learning and growing on their own. They don’t need to be told what to do, how to train, what to use, they don’t need nannies & micro management. They need an end state and they’ll get it for you. Frankly that kind of skillset and ability scares the shit out of some bosses as they micro manage actions & items instead of doing their jobs. You can’t use force, treats or authority to make people achievers. In the end you can cut a diamond, but you cannot create it. Trust me. Putting that amount of pressure on someone that isn’t a diamond only turns them into a heap of crushed remains of what used to be a human being or FTE in your typical HR speak.

“Mate you’re not a conformist” my friend said … you’d better believe I’m not Winking smile

Shameless Plug For Mastering Hyper-V Deployment By Aidan Finn


In October 2010 Aidan Finn (MVP) his book “Mastering Hyper-V Deployment” was released and in November three copies of this book landed on my desk. I bought them (pre order) via Amazon. Nope I did not get them as a gift or anything. Why Three? Well that’s the number of people I wanted to get up to speed about Hyper-V and virtualization management and operations in a Microsoft environment.

His book takes you along a journey through a Hyper-V project that will teach you about virtualization in all it’s aspects. It also touches on many supporting technologies and products such as System Center Virtual Machine Manager 2008 R2, System Center Essentials 2010, Data Protection manager 2010 and System Center Operations Manager 2007 R2. No one book can be the only source of knowledge and understanding, but using this book as a start for both new and experienced IT Pros to learn about virtualization with Hyper-V will give you the best possible start. Consider it going to an Ivy league college on a scholarship paid for by Aidan’s experience and hard work. The subsidized tuition fee is the price of the book.

We feel a bit sorry that Aidan only got one copy so we made a group picture of the gang of three on the desk of our newest team member. He got a copy of the book together with 4 recycled PC’s and a TechNet subscription to build a lab.

If you know people who want or need to learn about Hyper-V, you’d do well to make sure they get this book and have them set up a lab to play with the technologies. Those efforts will pay off big time when they implement their solutions in the wild. If Ireland is doomed it won’t be because of smart & hardworking Irish IT professionals like Aidan. You see when you design, build and support IT solutions that your customers depend on 24/7 you can not hide behind false promises, you can’t fake away the fact when “stuff” doesn’t work or hide behind vast amounts of papers & documents void of any substance. Nope you are responsible for everything and anything you build. Aidan backed and supported by some very knowledgeable colleagues has made that burden a bit lighter for you to bear with this book.

Cheap IT Support Requests & The Value of Time


I value my time tremendously. I also accept the fact that you don’t give a rat’s ass about my time. To you every hour I spend not working on your issues is a gigantic waste of time, but to me, it is not. And this is about my time. You cannot get time back, once used it’s gone. You cannot sell memories to get time back. You can’t produce time. You can’t save time. You have what you have and you need to use it when you have it. What does this have to do with IT? The fact than when you’re in IT people almost expect to get advice and support at no cost or on the cheap. This behavior stems from the fact that for some reason they expect that when they buy a server and software all the rest is included for free. With a car they don’t have this mind set. They expect to pay for maintenance, insurance, road taxes and gas. Partially this is the industries fault since they market everything a great, easy, fast, and cheap. Partially it’s the buyers fault for believing commercials and sales men. So how do I deal with the ever returning attempts to get me to work for free and how do I make sure they stop asking. Very simply, I price myself out of “the market”.

One day I discovered this also works outside of IT. Everyone who knows me wouldn’t think of asking me to baby sit but once a female colleague did just that. I guess she was really desperate. Really very desperate I should add. I told her I was not interested. She insisted. I told her again that I was absolutely not interested. She decided to make a case that I should help her out. That’s asking for it. I told her it would be 150 €/hour. I got a speech that babysitting isn’t that hard and worth that much, that it’s unaffordable, that kids, a house mortgage, car payments and life are already expensive enough. All true but not my problem.  You see I do not want to baby sit and my time is very valuable to me. I asked her what day and time she needed a baby sitter, trying to get my point across. She said Saturday night. Oh, on a Saturday to Sunday night in a weekend, after office hours and no retainer for my services. That makes it 300 €/hour and for watching of the most precious and loved human being in your life that’s a bargain! Needless to say I was not hired and luckily never asked again. Mission accomplished.

Think about it, time is the most limited resource the human species has. As I said, you can’t get any more of it. Gone is gone. That makes it more precious to me than anything else.  That means I want to spend it as well as I can. So when it comes to work I try to do things I enjoy and that pay well enough so that I can have enough free time to do other things I also enjoy. This means that when I do work I will not do it at 1 € /hour. Why would I? Even if I can only work 40% of my time at 5 €/hour I’m still way ahead and have more time to myself. With some luck and effort the better paying work is also the type of work I like to do. Cool, two goals achieved in one go.

So why on earth would I baby sit or fix your IT mess (which I dislike) in my spare time (time which is extremely valuable to be)  for some pocket money given the fact that it’s not my job responsibility and I have no financial pressure to do so?  Now I don’t know a thing about babies but IT can get a lot more complicated and involved that the owner of the mess realizes. It takes a lot of time and it just isn’t worth it. So there is your answer. I don’t want to and that’s why I price it so highly. To make sure no one asks or agrees to it. With these of hand support requests, changes are you’re a small shop running a couple of servers & workstations that are mediocre at best. This is probably combined with some older, hopefully legal, operating systems and applications that might suck and have their own issues. The environment was probably not designed, is most likely mismanaged for whatever reason and most of the time you won’t like the recommendations (get Adobe Acrobat and Office of your server and stop surfing on it so you don’t get spyware on the box). You complain about how expensive the hardware is, that the software costs money, that the small business IT shop is expensive and can’t get it right like you want. Perhaps the reason is that they can’t do it for the price your willing to pay, you are asking for things that can’t be done or perhaps they are not very good at their business. Whatever the reason, somehow you think that I should fix all that for a token fee since you already paid all that money to hardware vendors, software vendors, your “IT Guys” and because it won’t take me very long since I good at what I do. Well, it doesn’t work that way. My rate is not determined by how easy it might be for me. It’s determined by my knowledge, expertise and quality of my work. I don’t do the easier work as that won’t get me as much money for the same amount of time and I get bored doing it.

Am I a money hungry capitalist pig? No. I will and do work for free for a good cause, a close friend or a sport club I sympathize with. It’s called voluntarism and you can beat that as a motivation. I will not spend my valuable spare time fixing a mess that I did not create for free or cheaply. Actually I rather have my time to myself even when the money is good. You see, you’re in that mess because you don’t know what you’re doing; you’ve had very bad counseling or services and perhaps want things you can’t afford or are willing to pay for. The effort and cost of fixing all this is probably going to make you shout at me in anger. The impact that will have on your business processes and culture is something you’ll find unacceptable. The cost and needs of a professional IT environment are beyond what you can grasp, are willing or capable to pay. So the best thing for you is use free, cloud based services and make due with what you have or can get from those services. You cannot expect people to feel obligated to fix your problems because you already spent so much money on it. My free time at night and weekends is for studying, reading, hobbies, and friends. Not for fixing other peoples problems. So if you need a good environment hire one or more good IT partners to take care of your infrastructure needs in a professional manner. That’s the only sustainable and workable way of doing it.

The Dilbert® Life Series: Enterprise Architecture Revisited One Year Later


The Dilbert® Life series is a string of post on corporate culture from hell and dysfunctional organizations running wild. This can be quite shocking and sobering. The amount of damage that can be done by "merely" taking solid technology, methodologies, people and organizations, which you then abuse the hell out of, is amazing. A sense of humor will help when reading this. If you need to live in a sugar coated world were all is well and bliss and think all you do is close to godliness, stop reading right now and forget about the blog entries. It’s going to be dark. Pitch black at times actually, with a twist of humor, if you can laugh at yourself that is. And no, there is no light to shine on things, not even when you lite it. You see, pointing a beam in to the vast empty darkness of human nature doesn’t make you see anything. You do realize there is an endless, vast and cold emptiness out there. This is not unlike the cerebral content of way to many people I come across by in this crazy twilight zone called “the workplace”. I believe some US colleagues refer to those bio carbon life forms as “sheeple”.

Last year my very first blog post (http://workinghardinit.wordpress.com/2010/01/16/hello-world/) was about the one and only meeting I ever had with the Enterprise Architecture consultants that came in to help out at place where I do some IT Infrastructure Fu. Now one year, lots of time, money, training and Power Point slide decks after that meeting, the results on the terrain are nowhere to be seen. Sure there were lots of meetings, almost none of which I attended unless they dragged enterprise architecture into an IT related meeting on some other also vague action items like the IT strategy that was never heard of again. They’ve also created some new jobs specifications and lots of lip service and they’ll probably hire some more consultants to help out in 2011. But for now the interaction with and impact of any Enterprise Architecture on their IT infrastructure is nowhere to be found.

We put a good infrastructure plan in place for them. It’s pretty solid for 2011, pretty decent for 2012 and more like a road map for the time span 2013-2014. Meaning it’s flexible as in IT the world can change fast, very fast. But none of all this has come to be due to insights, needs, demands or guidance of any enterprise architecture, IT strategy or business plan.  No, it’s past experience and gut feeling, knowing the culture of the organization etc.  Creating strategies, building architectures is difficult enough in the best of circumstances. Combine this with fact that there is a bunch of higher pay grade roles up for grabs and the politics become very dominant. Higher pay grades baby? What do I need to get one? Skills and expertise in a very critical business area of cause!  Marketing yourself as a trusted business advisor, taught leader and architect becomes extremely important. As you can imagine getting the job done becomes a lot more difficult and not because of technical reasons. My predictions for 2011 are that by the end the year those pay grades will have been assigned. Together with a boatload of freshly minted middle management, who’ll be proud as hell and will need to assert their new found status, they’ll start handing out work to their staff.  Will that extra work materialize into results or only hold them back from making real progress? Well, we’ll need to wait for 2012 to know as 2011 will be about politics.

Basically from the IT infrastructure point of view and experience we have not yet seen an Enterprise Architecture and I don’t think they’ll have one in the next 12 months. Perhaps in 24 to 36 months but by then the game plan in IT infrastructure will be up and running. So realistically, I expect, if it leads anywhere against expectations, the impact of an Enterprise Architecture will be for 2014 and beyond. Which means an entirely new ball game and that will need a revised architecture. The success of the effort will no doubt be that they detected the need to change. This sounds uncomfortable similar to the IT strategy plan they had made. So for now we’ll do for them what’ we’ve always done. We’ll work with one year plans, two to three year roadmaps combined with a vision on how to improve the IT infrastructure. The most important thing is to stay clear of ambition and politics. Too much of that makes for bad technical decisions.

You got to love corporate bull. They don’t lie, no sir, they just sell bull crap. Which is worse, truth or lies don’t even matter, just the personal agendas. Liars at least, by the very fact of lying, acknowledge the value of truth, so much in fact, they’d rather have you not knowing it. Most consultancy firms send out kids that are naïve enough to believe the scripts and don’t even realize they are talking crap. They are told over and over again they are right, the best and they like to believe this so much they really do. It’s a bit like civil servants at the EU. Pay people double their market value, sweet talk their ego’s all day long and they will become prophets for the religion of the day. No, I’m not saying Enterprise Architecture is bull crap. I’m saying that way too many people & companies claiming to do enterprise architecture are turning it into exactly that. IT strategies, architectures that are so empty and void of content that all those binders are thrown in a drawer never to be seen again. A fool with a tool is still but a fool. Agile methodologies or tools don’t make your programmers agile gurus just like owning a race car doesn’t make you a race car pilot. All of this has happened before, and all of this will happen again. Every new, innovative process, methodology or concept falls victim to this. The money grabbing sales crowd gets there paws on it and starts selling it as competitive advantage or even innovation in a bottle to the corporate sheeple & management failures that should know better. They end with less money, loads of wasted time and a shitload of dead trees. As a side node, this whole “* Architect” thing  has runs it’s inflationary course. We need a new professional status currency once more. Take care and keep laughing clip_image001!

Exchange 2010 Public Folder Worries At Customer: No existing ‘PublicFolderProxyInformation’ matches the following Identity


A customers was recently using the EMC GUI in their Exchange 2010 environment, having a look a the public folder properties when they got this error:

—————————
Microsoft Exchange
—————————
Can’t log on to the Exchange Mailbox server ‘DAGMBX.demolab.com’. No existing ‘PublicFolderProxyInformation’ matches the following Identity: ‘\demolab\HeadQuarters\FincanceDepartment\FiscalUnit’. Make sure that you specified the correct ‘PublicFolderProxyInformation’ Identity and that you have the necessary permissions to view ‘PublicFolderProxyInformation’.. It was running the command ‘Get-MailPublicFolder -Identity ”\demolab\HeadQuarters\FincanceDepartment\FiscalUnit” -Server ‘DAGMBX.demolab.com”.
—————————
OK  
—————————

image

Hey … when did this start?  They never complained about this before, but did they ever use it.This probably was actually the first time they tried to look/edit the public folder permissions after doing the following over the past month and in this particular order:

  1. Moving to Exchange 2010 SP1
  2. Removing the last Exchange 2007 servers from the organization.

Now I know about a bug that exist and that was recently blogged about by Dan Rowley in Exchange 2010 get-mailpublicfolder \name returns No existing ‘PublicFolderProxyInformation’. The point is that there should be a mailbox database mounted on the server that has the System Attendant mailbox associated with it.  However, this is not the case here.  The mailbox servers are member of a DAG and all of them host a copy of the PF. The replication runs fine, users can work with them, the remaining Outlook 2003 users report no issues. But there is more in that blog: “Basically the work around is to mount a mailbox store on the server that is generating the error, or if there is a database already mounted – verify the system attendant is properly configured to point to a valid homemdb.” Now that last point is interesting and indeed that was the issue here. On two members of the DAG the homeMDB attribute was not set. Now what could be the root cause of this? I don’t know, certainly not in this case. All things have been done by the book … Ah well, luckily the fix is not very difficult. We need to put a valid entry in the homemdb. In this case we’ll take the value of the DAG member that had it filled in. This seems to be the most recently created database in the DAG. In Exchange 2010 this is done as described below. Note we have a DAG here, so we can work with any database that has a valid copy on the server(s) in question.

How to check the homeMDB attribute value:

  • Start ADSI Edit and navigate to CN=Configuration,DC=,DC=,DC=/Services/Microsoft Exchange//Administrative Groups/Exchange Administrative Group (FYDIBOHF23SPDLT)//Servers/MBXServerWithIssue
  • Right-click Microsoft System Attendant, and then click Properties to display the  Attributes list and find the homeMDB attribute.
  • If the homeMDB attribute has a value make sure  it points to a valid mailbox database. If the value of the homeMDB attribute is empty (not set) or incorrect you need to fix this.

image

How Fix the homeMDB attribute value:

  • In ADSI Edit navigate to Start ADSI Edit and navigate to CN=Configuration,DC=,DC=,DC=/Services/Microsoft Exchange//Administrative Groups/Exchange Administrative Group (FYDIBOHF23SPDLT)/Databases."
  • Right-click a mailbox database that is local (NON DAG) or has a valid copy on the server (DAG) , select Properties and in  the Attributes list, select the distinguishedName, and then click View.
  • Copy the value of the distinguishedName attribute and close the dialogs

image

NOTE in this particular case we can copy the value that was filled in the homeMDB attribute on one of the DAG members. You might not have one set in any.

  • Right-click Microsoft System Attendant, and then click Properties to get to the Attributes list, click homeMDB, and then choose Edit
  • In the Value box, paste the value that you copied form the distinguishedName attribute
  • Close the dialog boxes and exit ADSI Edit

When you’ve don this you’ll find following entry in the application event viewer:

Log Name:      Application

Source:        MSExchangeSA

Date:          11/2/2010 3:25:59 PM

Event ID:      9159

Task Category: General

Level:         Warning

Keywords:      Classic

User:          N/A

Computer:      DAGMBX.demolab.com

Description:

Microsoft Exchange System Attendant has detected that the system attendant object in the DS has been modified. System Attendant needs to restart the Microsoft Exchange Free Busy Publishing Service.

image

After that, I wait 10 minutes to get AD replicated and make sure to close the EMC and start it again and voila, it’s fixed.

No ADSI Edit required to fix “Object is read only because it was created by a future version of Exchange: 0.10 (14.0.100.0). Current supported version is 0.1 (8.0.535.0).”


During the removal of the last Exchange 2007 SP3 Mailbox server after completing the transition of Exchange 2007 to Exchange 2010 SP1 we ran into the following well known error: Object is read only because it was created by a future version of Exchange: 0.10 (14.0.100.0). Current supported version is 0.1 (8.0.535.0).

 

image

The issue is that due to the coexistence of Exchange 2007 & Exchange 2010 we can no longer remove the public folder database with the Exchange 2007 GUI (EMC). But the public folder is not visible in the Exchange 2010 GUI (EMC) as it lives on an Exchange 2007 server. Trying to remove the public folder database manually using the Exchange 2007 GUI confirms this, you’ll get the same error.

This error has been described in some blogs as early as October 2009 on http://www.proexchange.be/blogs/exchange2010/archive/2009/10/28/remove-exchange-2007-mailbox-role-fails-with-error-object-is-read-only-because-it-was-created-by-a-future-version-of-exchange-0-10-14-0-100-0-current-supported-version-is-0-1-8-0-535-0.aspx and later on as recently as October 2010 on http://www.howexchangeworks.com/2010/10/object-is-read-only-because-it-was.html

The described solution/work around in these blogs get the job done perfectly, using ADSI Edit to delete the offending Exchange 2007 public folder database. It wouldn’t be the first time ADSI Edit saves an Exchange Consultants proverbial bacon. But if it can be done without using it I often recommend not to do it.  I’ve seen to many over eager deletions in ADSI Edit get people into trouble (like deleting a public folder database before it could be dumped safely without data loss).

For this problem, it’s not required to use ADSI Edit to get rid of the public folder on the Exchange 2007 Mailbox server. You can just fire up the Exchange Command Shell (EMS) in Exchange 2010 and execute following PowerShell command:


Remove-PublicFolderDatabase "E2K7MBX\SGPublicFolders\StoreSGPublicFolders"

Confirm   4: Are you sure you want to perform this action?5: Removing public folder database "E2K7MBX\SGPublicFolders\StoreSGPublicFolders".
[Y] Yes  [A] Yes to All  [N] No  [L] No to All  [?] Help (default is "Y"): y
WARNING: The specified database has been removed. You must remove the database file located in K:\E2K7Data\SGPublicFolders\PublicFolderDatabase.edb from your computer manually if it exists. Specified database: PublicFolderDatabase

This works just fine. I have no objections using ADSIEdit when needed but I don’t advise using it to others unless really necessary.In this case it just isn’t needed to fix the problem. For good measure I also deleted the storage group in which the public folder lived. After that the install went well end without any issues.
