I understand that this isBeta software, but I tried to joina system running Windows 7 Ultimate Beta to a SBS 2008 Standard domain using the http://connect method, return message was that this is not a supported operating system. I haven't tried to join manually yet as I ran out of time. I'll try that and update this soon.Had to hit the windows update site for printer drivers for an HP 2420dn, virtually impossible to get all printer drivers loaded in the install package, but couldn't that be part of one of the first updates from Microsoft? This is something that I wondered about when setting upXP and Vista systems. Overall first impression, boots faster, but so does an XP system that has not been loaded with Office and every other program that one deems necessary to have!! I haven't loaded any office software on this WIndows 7 system, yet. Other than Mozilla Firefox, and browser add ons, (Adobe & etc .....) and AVG 8 Anti-Virus. Reboot from start to finish after installing and update was less than 2 minutes. Timed it by accident, I noticed the clock increment by a minute as I clicked restart!!!!

I received the same error message when trying to use the http://connect method. To truly test and compare Windows 7 to my other MS operating systems I would like to use it the way I use my other operating systems; joined to my domain via the wizard with redirected folders.I hope to see this fixed this soon.

YOu could try this:http://blogs.technet.com/sbs/archive/2009/02/06/using-windows-7-beta-with-sbs-2008.aspxNote that this is an unofficial fix to use a beta OS with a production server. That may not be a good idea.Kerry Brown MS-MVP - Windows Desktop Experience
