From a newsgroup post: "In most cases, this kind of blue screen error is caused by the hardware or device drivers. I suggest you unplug all these hardware except the display card, then restart the computer into Safe Mode. Click Start->Run, type devmgmt.msc and press Enter. Delete the unplugged hardware items. Then restart the computer into Normal Mode for a test. If you do not get this problem, please install these hardware cards one by one to narrow down this problem."
From Microsoft (not too helpful for network administrators):
This error indicates that a worker thread completed and returned at IRQL DISPATCH_LEVEL or above.
The following parameters are displayed on the blue screen.
1 Address of the worker routine
2 IRQL that the worker thread returned at
3 Work item parameter
4 Work item address
A worker thread completed and returned at IRQL DISPATCH_LEVEL or above.
Resolving the Problem
To find the driver that caused the error, use the LN (List Nearest Symbols) debugger command:
kd> ln address
where address is the worker routine address given in Parameter 1.
