Please excuse my lack of knowledge in describing this problem
but I hope someone can understand what I'm on about.

I have system 1 connected into our ethernet through a DEC delni
in location1.

I have systems 2-4 connected into our ethernet through another DEC
delni in location2.

Systems 2-4 are up and running and know about each others addresses.

On starting up TCP on system 1 it cannot resolve the addresses
for systems 2-4.

If I tell it the address then it can communicate with them.

In addition systems 2-4 can communicate with system 1 from the
start.

Now, if I disconnect system 1 from location1 and plug it into location2
the whole problem goes away.  System 1 can suddenly resolve everyone's
addresses and all is well.

Can anyone shed any light on what is happening here ?

Regards
