SBS 2003 Desktop Locking up

Our Server Desktop is just locking up more and more often. It doesn't seem to effect the users. Exchange is still running all the apps etc but if I have to login to the server, either at the desktop or RDP its locked up. The mouse will move but thats about it. Not even the task manager will come up I have to hard boot it to be able to get into it to do anything. So if I have to login to change anyones password or etc.. There are no errors in the event log so I don't know what is causing it. When its locked it doesn't seem to effect the apps the users are using I just can't login and do anything unless I reboot it. Is there any way to fix this?

Sounds like something is leaking resources.  when you can run taskmgr and at non paged to the columns and watch if something is eating up non page memory. Esp. look for the conduit service running have seen this on several systems causing resource errors.

How can I do that, when the problem isn't happening there is nothing to look for, when it is the only think that works is the mouse
Once you are forced to reboot, immediately when it comes back up open taskmgr and add the nonpaged memory column to your processes view, watch the non paged count if a process is eating up the non-paged memory it will start doing it right away, watch the nonpaged values for one that keeps going up especially after it has been running for over 20-30 minutes has it should be done with start up by then.  Are you using rdp to svr?
sorry didn't finish rdp from multiple systems? make sure you log off session not disconnect
