Server 2008 blue screen after login - no desktop
You should remove that software restriction policy and try again. It's most probably the cause, I guess. (It's always the last thing you changed... :) )

I came into work today to find that our Windows Server 2008 used as a terminal server for the Thin Clients was not loading the users desktops. What I have found out is that when I login via Remote Desktop, after applying user settings, it gets to the stage of 'Preaparing your desktop', but then the screen just goes blue.
I have tried rebooting several times with no luck, and logging in locally at the server with no luck. Does anyone have any suggestions?
I do not think that it could be a virus attack as we run antivirus on the server with OpenDNS filtering. Yesterday a software restriction policy was set up to only allow programs in the following directories to run if that could be the problem, although it was working fine all day yesterday.
- C:\program files
- C:\programdata
- C:\windows
Thank you.

Adam Thompson almost 12 yearsDo you need to add some other directories (eg D:\Program Files or C:\Program Files(x86))? Also - check if you have any logon scripts defined which call an executable from a UNC somewhere? I've seen logon script hold-ups cause this blank blue screen issue in Citrix farms.

Jake almost 12 yearsHi, no everything is on the C drive, and as it's a 32bit installation there is no additional 32bit folders. No logon scripts are set to run. When I sat locally at the server and pressed CTRL ALT DELETE, I was presented with this error: Log on process has failed to create the security options dialog. Could this be a fault with the logon service?

However when I press CTRL ALT DELETE I get this error: The logon process has failed to create the security options dialog. So maybe it's a logon service issue?

Jake almost 12 yearsHow can I go about removing the GPO object, as when I boot in safe mode the domain controller cannot be contacted, and when I boot normally I get the blue screen with no desktop etc. I've tried RSAT on Windows 7 but then I get this: The specified domain either does not exist or could not be contacted. Any ideas?

MichelZ almost 12 yearsSoftware restriction policies are stored in the registry. I assume a computer GPO is used, try to delete this registry key in safe mode:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Safer
