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.
