SYMPTOMS
When you run the Japanese or Korean versions of Windows NT 4.0, the system displays a blue screen error message. When you examine the call stack, you see an access violation in either of the following:

  win32k!HMMarkObjectDestroy

win32k!HMAllocObject

The blue screen error message would be displayed as a STOP 0x1E in Win32k.sys

STOP: 0x0000001E ( 0xC00000005, 0xA0036FC2, 0x00000000, 0x00000004) K_MODE_EXCEPTION_NOT_HANDLED address 0xA0036FC2 in Win32K.sys



CAUSE
HMAllocObject is not supposed to run in parallel, but it was being called simultaneously from multiple threads:

HMAllocObject <- GetCPD <- _GetClassInfo <- NtUserGetClassInfo



RESOLUTION
To resolve this problem, obtain the latest service pack for Windows NT 4.0 or Windows NT Server 4.0, Terminal Server Edition. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
