Windows 7 PC Windows 7 Pro stuck at the login page when any user access to it

[Atlantidee]

Hello.

I have a Windows 7 Pro 64bit in a Domain. The Domain server is a Windows Server SBS 2008. The PC is used by 10 user via terminal server (remote desktop) using a third part software, Thin Stuff.

The PC stuck after a user log with username and password (via RDP). So the PC stay forever in the loading screen with the Windows logo and the user desktop never appears...

I notice those 2 errors often repeating in the Windows 7 PC event log:

It's like the PC doesn't reach the domain server but they are connected to the same switch. After a forced reboot all users are able again to access the PC without any problems.

The Windows 7 Terminal Server PC has installed NOD32 version 13.
