Question : Windows 7 machines Cannot Join Domain

Hello after upgrading some workstations from XP to Windows 7 Enterprise; all Windows 7 workstations are logging in onto the domain with a temporary profile.
How can this issue be corrected; thus profile changes would be committed to their respective profiles.
 I am currently using roaming profiles in my domain setup.

I tried rejoining the machines to the machines back to the domain after Windows 7 upgrade and it was successful.

The problem is that when that user who was using Windows XP earlier to load his profile, It logs him in with a Temporary Profile; thus all changes he or she makes to his personal domain profile is deleted after he/she logs off from the machine.

I personally read about deleting some SIDs from registry but I really want to be sure before making any changes to the workstations registry.

I need more clarification on this issue. Thanks!

If you are in a mix mode environment with XP and Win7 using roaming profiles you are going to have some issues arise like this. Windows 7 stores the profiles in different directories and also has a different naming convention for the profile folders (v2).

Because you are in a mix mode environment you are going to have to manage 2 profiles for each user (1 for XP and 1 for Win7).

What I would suggest is using the USMT (User State Migration Tool). Take a look at the following link to get more information on the USMT.
