Problems at the site I manage sound similar, but not the same:  Our macs 
plug in thru phone wiring to MaxTalk cards for Access/1 from 
Ungermann-Bass, each of which has 16 lines which each mimics a Kinetics 
Fastpath, I believe.   As above, Telnet without MacTCP works fine.  I 
installed about 50 macs with MacTCP (patched version 1.0) using Dynamic IP 
addresses.  All MacTCP programs worked when I first installed them a few 
weeks back.   Now I find that every so often, all MacTCP programs on some 
of these Macs will fail for at least a few hours.   They will sometimes 
recover and start working, sometimes not.  When I try MacTCP 1.0.1, they 
same problem occurs.   The macs will aquire a dynamic IP address from the 
MaxTalk card (which I can see with Interpoll), but programs all fail, 
regardless of whether name or number is used to address a host.  When I 
try Static IP addressing, MacTCP programs all work.
