Subject: Bridging Servers - Error "Server not responding"
Date: January 23, 1991

PROBLEM: Two file servers that were bridged together internally each
had three network cards. The watchdog timer was kicking the
idle workstations off the network after fifteen minutes. It
would also kick the workstations off file server 1. When
trying to attach to file server 2 through the internal
bridge, the system would hang with the error SERVER NOT
RESPONDING.
SOLUTION: In most cases these problems are caused by network address
conflicts (LAN or card), cabling, or card problems. In this
particular case, file server 1 had network addresses 2, 3,
and 4 respectively and file server 2 had network addresses
2, 3, and 4. The file servers were connected through LAN A,
card address of 2 on both file servers. On LANs B and C,
the cards, addressed 3 and 4 on each file server, were going
to workstations.
NOTE: THERE WERE NO ROUTER CONFIGURATION ERRORS
COMMENTS: The router configuration errors will only be seen if two
or more cards on the same LAN are claiming to have different
LAN addresses. The router tables are very simple top down
format and the file server will send the packet out the
first LAN that matches. This is why you get kicked off.
