I'm getting this strange problem which I can't seem to find a solution for.
Randomly our users computers freeze up on the Welcome Screen when trying to login and the only way to fix it, is to reboot the machine unplug it from the network and then log in and reconnect to the network.
The Event log has so far been no help, it only happens when connected to network at work ,ie the domain, when connected to other networks no problems.
All machines are running Windows 7 Professional x64; DC’s are 2008 R2 Enterprise.
Thanks for your help.
