Here at VIMS (Virginia Institute of Marine Science) we have a mixed
platform environment. We used to have a bunch of routers built on 286 boxes
that only routed TCP/IP (ie AppleTalk traffic was blocked). Now we have
removed those routers and we have a big "mess" of Macs, printers, etc that
show up on the network.

We decided we needed to implement zones. We have a mix of Sun Unix boxes
and a couple NT server systems. We have a server which does RIP processing
for a variety of printers called a Jetstream, which is really an SGI Indy
inside. The Jetstream is speaking AppleTalk through Xinet software (old KA
Share) which the Jetstream people decided to use to do AppleTalk on the
Indy.

Back when the subnet I'm in was surrounded by those 286 based
routers/blockers we successfully used one of the Sun systems running
NetaTalk to seed zones. However, we decided to use the NT server as the
zone seeding source. We went into the Network Neighborhood properties and
added "Services for Macintosh". We turned on AppleTalk routing and selected
"Use this router to Seed" and defined some zones. By the way, we are using
Windows NT 4.0 SP3.

After turning on the AppleTalk routing we tried to find the zones on the
Macs and they showed up on some and not on others. Through turning
AppleTalk off and back on and/or rebooting some of the Macs we got the
zones to show up. However, they would disappear after a few minutes, in
basically a random manner.

The next thing we noticed was that the Jetstream RIP processor (the Indy
running Xinet) took a dive. We couldn't get it back in operation, even with
rebooting. We also looked at a couple of the Sun servers that were running
NetaTalk. We found they were logging error messages "VM Unix Mbuff full".

Finally we shut down the Windows NT zone seeding and everything returned
to normal.

Does anyone know why zone seeding on a Windows NT Server didn't work for
us? Has anyone successfully done zone seeding in a mixed environment like
ours? If so what did you use to do the zone seeding?
