Move to SBS2003R2 from 2003 STD Domain

from 2003 Std to SBS 2003 R2. I personally have not setup SBS server, as most of my customers are too large for SBS, but I'd check first if I were you because it's like going from enterprise sever to standard server if you ask me. SBS I would assume would not have all of the schema extensions and other services of a full blown standard or enterprise edition server. Regarding profiles, you have two options here. If you are not using roaming profiles, it shouldn't be an issue since the profiles are local on the PC and as long as you're not changing the PC or overriding the local profile with some GPO mandated profile, you won't have an issue. If you are changing PCs', then you would have to use the files and settings transfer wizard (migwiz.exe) on the XP desktop to export the desktop settings to a file and import it on the new machine. If on the other hand you are using roaming profiles, then it should be as simple as moving the profile to a new shared folder on the new DC and repointing the user objects to their roaming profiles on the new server shared folder location. Since the profile really has nothing to do with the server itself and controls the desktop settings, nothing would get changed except for any shortcut icons on the desktop that would still point to the old server drive shares, which obviously would be invalid.
