I have a Windows 2003 Server which functions as a web server that is behaving strangely this morning. When I try to RDP into it, it fails. So I thought I'd try using PSEXEC to kick RDP into submission. PSEXEC fails as well.
Browsing to sites hosted on this server is successful, and viewing shared folders through Explorer works as well.
So I go to the server's physical console, and CTRL+ALT+DEL to get the login box. Login box comes up, I enter my credentials, and it immediately kicks back to the CTRL+ALT+DEL screen. So I enter that again, try my creds again, and again, kicked back to the CAD screen.
I've tried various accounts that should be able to login to this server with the same result.
I remotely manage the server, and check its event log. It has an error about Terminal Services terminating unexpectedly. So I Restart that service. Now RDP doesn't error out right away, but instead sits at "Configuring remote session". The console still behaves as described above.
Whenever I attempt logging in from the console, an Error 1218 is registered in the Application Event Viewer.
