We recently started to deploy Windows 7 machines onto our school network. We have a Windows domain running Windows Server 2003 R2. When logging off or switching users, the monitor will lose signal, turn black for 12-13 seconds then return to the login prompt. At this point, the mouse freezes and will only work after powering down the system or reconnecting the mouse. The mouse problem only occurs with USB mice, not PS/2. USB keyboard is unaffected.
After some troubleshooting, we found this problem only occurs when switching domain users or logging off of a domain user account. When switching or logging off of local user accounts, the problem does not occur.
All recent Windows updates are installed and we've updated hardware drivers and the BIOS.
Any ideas would be greatly appreciated.
