I have a Windows SBS 2003 R2 server that has a strange problem. If the server is left running for approximately 4 days, I cannot get the login screen to appear at the console - all that displays is a blank grey screen. Weirdly I have no problem logging into the server remotely (using RDP) and in every other respect, the server is performing faultlessly. This inability to login at the console continues until the server is restarted at which point everything is fine for about 4 days and then it happens again!
I have researched this problem on the internet and although there are lots of cases of people experiencing the GSOD (grey screen of death), they seem to get this both at console and remote login.
This problem only started to occur recently and changes to the server during this period have been minimal - only Windows Updates and some maintenance patches for Backup Exec 12.5.
I have also examined the Windows Event Log and cannot find any error relating to this problem.
Any advice would be greatly appreciated.
