First some software details: Thin client: Wyse C10LE Citrix - Windows Terminal Services - Windows Server 2008 Enterprise desktop I have a user with a very strange problem. When he locks his screen with Win+L, Windows claims he's entering wrong password when he tries to log back in. The only solution is to hard reboot the WYSE, and log back in. This reboot doesn't kill his Windows session. I've checked for errors in keyboard settings (wrong layout etc), nothing found. I suspect errors in his profile/errors in AD. No other users in the domain has this problem. EDIT: Sorry, it's NOT Win R2. Plain Windows Sever 2008
