We use windows 2003 server as domain controllers/file servers with our clients using Windows 2000 professional (Office 2000 Professional) on mostily Dell Optiplex 270s (and some other pcs).
We are experiencing an intermittant problem where a user tries to access a file on the network such as:
* Open their my documents (which is redirected to a directory on the server)
* Save a file to the my documents.
The machine will freeze for about 5 minutes with task manager showing 0 or 1% processor usage, any icons in the system tray will freeze, the mouse pointer remains active but you cannot switch between windows, the task bar becomes inoperative. Often another application can be brought to the foreground before the taskbar freezes and that app continues to work properley (ie outlook can still send and recieve emails) but the application that was trying to save will not come to the foreground.
Ctrl-Alt-Del jumps to the window with the 6 buttons (change password logoff etc) but then clicking task manager results in a blank screen (background only) with a taskbar with no buttons drawn. Further Ctrl-Alt-Del has no effect.
Eventually (about 5 minutes) the system recovers, the file is saved or action is completed and everything is happy.
Have tried the normal things:
* deleted all the normal.dots (thought it was a problem with word but it can happens when you open my documents with no other apps running)
* deleted and recreated the profile
The problem is evident on machines with and without our virus software (InnoculateIT) installed.
The problem can not be replicated every time, most of the time the system works as normal.
A reload of the OS results in a few days of problem free activity then the problem reasserts.
Nothing is logged in event viewer.
We are running Windows 2000 SP4 with all relevant updates.
Thanks in advance for any help.
