Are the macs and server on the same segment? If so, there's something
very dodge with your network. Trouble is, debugging Appletalk's a bitch.
First, run statnet to see your loading on the network. If the segment's
saturated, there's your problem.
Second, make sure ALL macs are talking Ethertalk II.
3, use only 1 or 2 cable ranges. Please let me know if you are using
a _large_ cable range like 100, and if this fixes the problem.

Yes if the network is heavily loaded. Also, it could be a problem if
you're running 802.3 as your frame type. (802.3 has no way of
differentiating protocols). You can force the PC's driver to use
802.2 SNAP in the .cfg file, and I'd recommend you do that. EthertalkII
as a frame type is also cool.
Hope something here helps.
