Under stressful conditions in Windows NT 4.0, TCP/IP may cause a deadlock on a multiprocessor computer, putting the computer into a non-usable state.
This problem happens because the thread on one processor has already allocated a tcb_lock and then the calling function tries to lock the TCBTableLock. Then, on the second processor the thread has a lock on the TCBTableLock and the calling function tries to get a tcb_lock.
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:
