I have a Dell PowerEdge Server 1550 with Windows 2000 Server installed. This weekend I decided to reboot the server since it had not been rebooted in quite a while and after rebooting I found out all services loaded but no applications will run. Here's a detailed description:
The server starts up, Windows 2000 Server loads, asks for Administrator password, and after logging in nothing happens (explorer.exe doesn't load so no desktop, no icons and no task bar are available). I open up the Task Manager and find all services loaded (there's e-mail, web services, etc, everything works fine) but no explorer.exe... I try tu run it manually but it only shows up in the process list for a fraction of a second and then disappears. I try tu run "cmd" but the same happens. Any application I try to run does exactly the same (appears in the list for a fraction of a second and then closes).
Rebooting in safe mode presents exactly the same scenario. I tried rebooting in safe mode with command prompt (which worked) and tried to run "sfc /scannow" but it says the RPC server is unavailable. I tried booting from the Windows 2000 Server CD and from the Repair Console ran "chkdsk /r", it ran for a while and then said one or more errors were found and repaired. I rebooted but everything's still the same.
I'm stumped, any ideas? This is a mission critical server so I can't take it offline too much time. The only good thing is that all services are running fine including Exchange, IIS, Lotus Domino, etc.
