Problem:
Logon and load profile via LoadUserProfile API for a roaming user is not creating proper profile. This only happens under Windows 2008 (UAC off and on). Login using standard windows logon works correctly and same code works correctly on Windows 2003.
Logs:
- http://drop.io/6t2b3f3 ETL of user profile service created via command: logman -start profile -p {eb7428f5-ab1f-4322-a4cc-1f1a9b2c5e98} 255 3 –ets The file needs to be analyzed by someone with access to the source and hopefully that will shed some light on why the profile is always loading as temporary.
Environment:
- Windows 2008 mode domain/forest
- Server fs001 - Windows 2008 Standard SP2 x86 box
- File share on fs001 "Share" with Everyone+SYSTEM having full control on share and ntfs.
To reproduce:
- Create domain user tuser1 with roaming profile set to \fs001\Share\tuser1\profile
- Run this program as any domain admin and local admin account on fs001 (if UAC is on run as administrator), a temporary user profile is loaded in c:\users\temp* rather than c:\users\tuser1
The ETL is probably the best way to go here and will be provide the quickest diagnosis. Procmon of user profile service svchost instance and tracing logon on the system level did not reveal too much about what's going wrong (I can provide more info if necessary but it's a dead end). userenv.log on Windows 2003 would have helped but ETL can only be analyzed by someone at MSFT.
Any ideas?
Thanks, Alex
