We have got a problem with a domain controller running on Windows 2003 R2 std, SP2. It's a Dell T300 (4GB)
Almost every day (not structural) the server "hangs".
The users which are already logged in after the server hangs, are not able anymore to approach the server (like network shares, network applications crashes, etc).
Users which login after the server hangs, are not able to login.
When we log in on the console the crtl+alt+delete function is working and we can put in a password, then the settings are loading.... but then nothing happens for a long long time. So the server is not freezing.. but only a hard reset will do the trick..
The logs don't display any events which can be cause this problem. Also performance logs will not show any errors..
We request a case by Dell. Logs will not show any hardware failures..
