I’ve had the distinct pleasure of tapping into the knowledge of Jose Barreto and learn that the Netdom Computername that provides alternate names for windows 2008 (R2) works with SMB 2.0. We deliberately stayed away from DNS aliases in 2008 for some file servers replacements in combination with disabling strict name checking because using that combination will revert back to SMB 1.0. That means you can’t take advantage of the improved throughput you get with SMB 2.0. Tonight I was happy to find out that netdom computername /add:<NewAltDNSName> will create a dns entry and SPN for that name and using it will not make windows revert to SMB 1.0. This is neat!
