A Windows NT Server with Service Pack 4 experiences a STOP 0xC000021a error when you run the Windows NT Resource Kit utility, pviewer.exe, or any performance utility that attempts to gather "costly counters" against it. Costly counters are a set of four data items that can be retrieved; for example, thread details, process image names that take extra processing to get the data for.
The Winlogon process causes an access violation with a C0000005 error, which in turn causes the trap.
To resolve this problem, obtain the latest service pack for Windows NT 4.0 or the individual software update. For information on obtaining the latest service pack, please go to:
Microsoft has confirmed that this is a problem in Windows NT 4.0 Service Pack 4. This problem was first corrected in Windows NT version 4.0 Service Pack 5.
