SYMPTOMS
When executing on a multiprocessor system, using Data Access Objects (DAO) or JET methods to retrieve or update recordsets and Querydefs can produce a hang condition in the application.
CAUSE
There is a race condition that can occur on a multiprocessor system when more than one thread is accessing a file at the same time. This bug has been identified within the NT kernel. Under the correct circumstances, when two threads attempt to use a file simultaneously, the thread closing the file can potentially be pre-empted. Because the final cleanup on the file is not performed, all the threads attempting to access the file enter into a wait state from which they do not return.
RESOLUTION
This issue has been addressed in a Microsoft Windows NT 4.0 hotfix. For directions on how to obtain this hotfix, see the following Knowledge Base article:

STATUS
Microsoft has confirmed that this is a problem in Windows NT 4.0.
