Help!

We have about 10 machines (VAXen, 68Ks, Z8Ks, and PDP-11s)
connected together with a 10 Mbit Ethernet (running 3Com's UNET
software) and find that sometimes some pairs of machines
refuse to talk to each other.  The 68Ks and the Z8Ks
are MULTIBUS machines, and all machines use 3Com Ethernet controllers.

Example:
	Alpha, Beta, Gamma, and Delta are on the net.
	Alpha can talk to Beta and Delta,
	Gamma can also talk to Beta and Delta,
	Beta and Delta can talk to everyone,
	but Alpha and Gamma can't talk to each other.

Has anyone else run into this sort of trouble?
Anyone have any hints or consolation?

If you think you know something about this,
please get in touch with me. I will provide details if they will help.
Thanks for your help.

Re: Trouble with pairs of 3Com ethernet machines not talking.

Boy, do I have egg on my face.  It turns out that I had an error
in one of the net routing tables (UNET.names); there was nothing
wrong with the 3Com software or hardware.

I'd like to take this opportunity to thank Bill Croft @ Sun
for passing my original message along to 3Com,
and to Pamela Lawson @ 3Com for lots of prompt help.
3Com gave me better support than I've gotten from any other company
with which I've ever done business.
I should have called them in the first place,
and spared the net.

Thanks also to Terry Laskodi @ teklabs and Rick Krull @ teklabs for their
helpful suggestions.
