We have a small network of Macs in out building, round 20 machines or so.
About 15 are Phonenet-connected, the rest are hooked up to a thick ethernet
backbone.  We use a FastPath 4 to tie the nets together.

We are now experiencing the follwoing problem:
	Rather consistently (every minute or so), Macs connected to either
network will freeze up momentarily, where all activity (mouse movement,
keystrokes, etc.) will go ignored.  After 2-3 seconds, the machine will
come alive again, and any entered keystrokes will show up.

This occurs regardless of the amchine type or network hook-up.  I suspect
the network, because taking the machine off appltalk will resolve the problem.

This is a small network with no gateways to the outside world.  We have about
12 Mac IIs, 8 Mac SEs, 2 LaserWriters, and the FastPath gateway (running
Kstar 8.0).  I have defined 2 ethernet zones, one for Phase I & one for Phase
II.  The gateway is configured as a bridge betweeen the 2 zones.

I hope that someone out there might be familiar with our symptoms and take
pity on us, as I have little in the way of management tools at this time, and
I have been unable to diagnose the trouble.  Please email me, and I will
send replies to anyone who is interested (or post a summary, if desired.)

Thx,
