Title: MS-Redir Error 51
Date: 7/29/88

Copyright 3Com Corporation, 1991.  All rights reserved.

The error message "MS-Redir Error 51" occurs during a 3F LINK across a
NetConnect server.  He is on Ethernet and trying to link to a sharename
on Token Ring.  The Ethernet server is the NetConnect server which also
runs Name, File/Print, Mail and Backup.  Token Ring users are able to link
without getting the error.

SOLUTION:  This error means that the "Remote Computer is not listening."
It could be that the NetConnect setup was not done correctly.  Make sure
the Domain was added first and then the Server name, also check the
Network # in the Netconnect window.

Also, "MS-Redir Error 51" and "Share Server Not Responding" are error
messages I used to receive on my workstation when trying to link to a
NetConnected server that had too many unterminated remote links.

The problem occurs when a netstation with an inter-net link reboots
and doesn't unlink or logout.  Login's broadcast to terminate open
sessions is not broadcast across NetConnect and eventually a server
will acquire too many sessions (the number of Remote Sessions equals
the Number of Msg Buffers in the Installation & Config Share screen
minus 1).

Workarounds include:

1. Be sure that everyone logs out and doesn't just reboot.

2. Increase your I&C Share Msg buffers (max is 35, but it uses memory).

3. Have the Remote Network's Administrator force unlinks.

4. Reboot the offending sever periodically.
