Event ID 12053 Caused by Macintosh Client Disconnect

Last reviewed: August 21, 1997
Article ID: Q136300

The information in this article applies to:

  • Microsoft Windows NT Server versions 3.5, 3.51, and 4.0

SYMPTOMS

The following error may appear in Event Viewer when you use Services for Macintosh (SFM) on a Windows NT Server:

   Event ID: 12053
   Session from user "USERNAME" was timed out and disconnected by the
   server. The AppleTalk address of the Macintosh workstation is in
   the data.

CAUSE

The server generates the error when it has lost the connection with the Macintosh client. The error may occur for any of the following reasons:

  • The Macintosh client has a file open on the computer running Windows NT Server and the server is restarted, or the Macintosh client is restarted, while the file is open.
  • The Macintosh client has a connection to the computer running Windows NT Server (no files open) and the server is restarted, or the Macintosh client is restarted.
  • When the network connection between the Macintosh client and the computer running Windows NT Server is broken because of possible network problems.
  • The Macintosh client receives a system error, such as a Type 1 or Type 11 error, which forces the client to restart.

WORKAROUND

To avoid this problem, make sure you close all files and connections to the computer running Windows NT Server before you shutdown your Macintosh client.
