We have an appletalk network set up in a passive star configuration. It
presently has about ten branches. But here is the problem. One of the
computers on the network is a CX. The connection was working fine for a
while, and then after installing Shiva software, the file server and the
laserwriters on the network couldn't be seen. I then brought an SE/30
up to that office and hooked it up and everything worked fine. The
ports on the CX were checked and they are working fine. I have no idea
what is causing the CX to have problems.
The first thing I will do is get the network back into specs be making
it have only six branches, but I don't know why it would be working
before and then not work. And then, only the CX doesn't work.
Any ideas?

And then, only the CX doesn't work. Last time I read one of the Farallon PhoneNet handbooks, they recommend no more than 4 branches on a passive star. When they talk to you in tech support, the one thing you hear over and over that nets within spec nearly always perform as expected, but with nets out of spec, all bets are off. When I first went through wiring up a PhoneNET setup back when they first came out, I had incredible numbers of problems keeping the net up. Especially when our phone people came and tried to wire the net up to a phone system configured with passive stars branching off passive stars. One node more or less could make or break the whole thing. I always dreaded any new machines coming online.
