[comp.protocols.tcp-ip.ibmpc] Invisible machines to TCP/IP

Help!

TCP-IP network consisting of PC-AT clones running Wollongong tcp-ip
and an ATT 3b2 running Wollongong win/tcp 3.0.

When isolated from the rest of the network, I can telnet from the
PC's (if they are configured NOT to have a name server) to the 3b2.
BUT when I attach to to our local part of the real network, the 3b2
becomes invisible -- the pc says it isn't there!!

Any thoughts??
