Connections to Share-Level Server May Fail

 Last reviewed: November 11, 1997
Article ID: Q139506
The information in this article applies to:
  • Microsoft Windows NT Workstation versions 3.51 and 4.0
  • Microsoft Windows NT Server versions 3.51 and 4.0

SYMPTOMS

It is possible for multiple logon sessions to be in progress simultaneously from a single workstation to a single server. For example, the interactive logon user may initiate an interactive logon session and a service may initiate another session. These logon sessions are multiplexed over a single virtual circuit (VC.)

When such connections are established to a share-level server such as Windows 95 or LAN Manager running share-level security, the session may be terminated unexpectedly when one of the users log off.

Applications may receive one of the following error messages:

  • An unexpected network error occurred
  • System error 59 has occurred

CAUSE

The Windows NT redirector incorrectly sends a logoff&X Server Message Block (SMB) to the share-level server when other sessions exist.
