Unexpected Result in NCB Callname After Canceling a Listen

ID: Q162681

The information in this article applies to:

Microsoft Windows NT Workstation versions 3.5, 3.51, 4.0
Microsoft Windows NT Server versions 3.5, 3.51, 4.0

SYMPTOMS

A Windows NT NetBIOS application's network control block (NCB) may appear corrupted. If Ncb.listen is posted with an asterisk (*) for the called name, the string "nnection context" is returned in the NCB callname structure whenever Ncb.listen is canceled before a client responds to it.

CAUSE

The remote address of the client should be copied to the NCB structure on the completion of the listen. However, because a client did not respond to the listen, the unexpected string is copied to the structure.

STATUS

Microsoft has confirmed this to be a problem in Windows NT versions 3.5x and 4.0. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

Because the NCB callname is not used when Ncb.listen is canceled, this problem does not negatively affect NetBIOS applications.
