Very interesting.  I wonder why someone would tweak those values on the
server in the first place.  Unless all the devices on a LAN segment are
using the same values, problems are going to arise.  From the sounds of
it, someone changed the server settings and didn't bother to let
everyone else know!

Yup, I made the changes on the TokenRing interface itself, not the WAN
interface.  The original config I posted listed just one of the routers
that
was connected via a serial interface (all T1 lines).  There are
actually 7
serial connections to this and five token rings.  Each interface is its
own
separate network.

I think the problem is like this:  The Cisco router is looking for RIP
and
SAP updates every one or three minutes by default.  If your server is
configured to send out RIP and SAP updates at any interval greater than
what
Cisco is looking for, then Cisco forgets the route to the server.  By
matching the Cisco RIP and SAP update interval to whatever is set on
the
server on the network, there should never be an interval greater than
what
is allowed to keep the route.

As to whether or not this command should be placed on the WAN
interfaces or
the LAN interface, well, it was already set on all the WAN interfaces
so it
looks like it has to be set on each interface where a SNA server is
located.  The only interface that did not have the command was one that
went
to another network that was all NT, no IPX at all.
