[Samba] roaming profile corruption with windows xp client and samba PDC
Hi, I have roaming profile issue on my SAMBA PDC with an LDAP backend running on FreeBSD 6.3. It seems that randomly, user's profile get "corrupted" on windows XP. When that happens, the user log in as usual (%userprofile% variable is set and all the share are properly connected) but he gets a default desktop configuration (default wallpaper, english keyboard layout...while i'm running windows xp french edition...) and every desktop settings he try to modify are not saved back on his profile and restored next logon. I don't know if it's relevant but the NTUSER.DAT file is renamed Ntuser.dat when that happens. While trying to debug this issue, i saw a lot of the following lines on the XP clients in %windir%\Debug\UserMode/Userenv.log file and i'm wondering if those error messages could be related to my issue please ? ---------------------------------------------------------------------------------------------------------------------------------------------------- USERENV(330.334) 12:37:13:343 CUserProfile::CleanupUserProfile: Ref Count is not 0 USERENV(330.334) 12:37:13:390 CUserProfile::GetRefCountAndFlags: RegQueryValueEx failed, key S-1-5-21-2211716236-2719219400-558165280-22480, error = 00000002 USERENV(330.334) 12:37:13:390 CUserProfile::CleanupUserProfile: Can not get ref count and flags USERENV(330.334) 12:37:13:390 CUserProfile::CleanupUserProfile: Ref Count is not 0 USERENV(330.334) 12:37:13:390 CUserProfile::CleanupUserProfile: Ref Count is not 0 USERENV(330.334) 12:37:13:390 CUserProfile::CleanupUserProfile: Ref Count is not 0 USERENV(330.334) 12:37:13:390 CUserProfile::CleanupUserProfile: Ref Count is not 0 USERENV(330.334) 12:37:13:390 CUserProfile::CleanupUserProfile: Ref Count is not 0 USERENV(330.334) 12:37:32:187 GetUserGuid: Failed to get user guid with 1355.

For example, when logged in with the credentials of one those users, i can't create a DWORD registry key under [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System] To workaround this issue, i have to rename the user's profile directory on the samba server (aka mv ~user/profile ~user/profile.bak) right now...till the next time it'll happen :( I have read a lot about this issue and it seems that it could be related to either: * Symantec Antivirus corporate 10. And i have this software running on some of the domain computers but not all * Enabling "The Cache Option for Offline Files" . And indeed, i forgot to disable this option on some of the computers (the same where symantec is running by the way :( I'm on my way to fix those configurations problems but would really appreciate any help on the userenv.log error messages pasted above please :-) Thanks.
