Dear all,

I get the error "The user profile Service failed the logon - User cannot Be Loaded" on a Server 2008 R2 RDS on some profiles.

My architecture is composed of 3 RDS server NLB.

Here are the actions that I have taken:

1/ Boot in safe mode with CHKDSK / F / R

2/ Check the "user profile login" service works and never stops.

3/ Kb followed this by removing .bak put the refcount = 0 and the state = 0 https://support.microsoft.com/en-us/kb/947215/ its works but after some time still the same error The user profile Service failed the logon - User cannot Be loaded "or temporary profile.

4/ Reapply the rights to C:\users\default

5/ Compress hives:
C:\ windows\system32\config\default
C:\ windows\system32\config\sam
C:\ windows\system32\config\security
C:\ windows\system32\config\software
C:\ windows\system32\config\system
C:\ windows\system32\config\components

6/ when I delete the corrupted profile and I create a new profile I also error coming back.

7/ I applied this kb:

Our infrastructure works for a long time with this setup and we never had the same problem. For information my virtual server is configured with 16 GB of RAM and 8 processor. I have 25 Go free space on the server.
We have a GPO that redirects the user profile following folders:

• Appdata
• Dektop
• Favorites
• My documents

Below I get errors in the event viewer :

Error 1508 : Windows was unable to load the registry. This problem is often caused by insufficient memory or insufficient security rights.

 DETAIL - Insufficient system resources exist to complete the requested service.
 for C:\Users\jack\ntuser.dat

Error 1502 : Windows cannot load the locally stored profile. Possible causes of this error include insufficient security rights or a corrupt local profile.

 DETAIL - The process cannot access the file because it is being used by another process.

Error 1515 :
Windows has backed up this user profile. Windows will automatically try to use the backup profile the next time this user logs on.

Error 1511:
Windows cannot find the local profile and is logging you on with a temporary profile. Changes you make to this profile will be lost when you log off.

Once I have the errors in the registry  in HKEY_LOCAL_MACHINE \ Software \ Microsoft \ Windows NT \ CurrentVersion \ ProfileList \ .... .bak and and when I open the remote session a cmd is displayed: c:\users\temp .

Thanks in advance.

Hi Tan,

It seems like constant user profile corruption to me.

If possible, I suggest you disable/uninstall third party software especially anti-virus, to see whether the issue persists.

Best Regards,

Amy

Hi Amy Wang,

I already uninstall software for anti-virus . We have again a problem.

Thanks
