SYMPTOMS
Applications that use the LookupAccountSid function on a multihomed system may intermittently generate the following access violation in the calling function:

Access violation (0x00000006)

ERROR_INVALID_HANDLE

The problem occurs when this function is executed in a separate thread for each attached network, on Windows NT computers that are attached to multiple networks.



CAUSE
After the second thread completes, it attempts to destroy the client context handle, using the same handle that was closed by the first thread. This causes the function to generate the access violation.



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:
