lost all network except ethertalk phase 2

[don gilbert]

Sometime today my a/ux mac lost ability to talk with the rest of
our campus and internet network.  Ethernet hardware and connection
is fine (works fine from MacOS); telnet is fine to the local loop;
AND telnet/ping/ftp is fine to another mac that I've switched to 
ethertalk phase 2.  Nothing else.   I don't know whether the problem
is with a/ux (I recently installed the 2.0.1 update) or with the local
campus network milleau.  All of our campus net is now on Appletalk phase
1, with cisco routers(?) which haven't been upgraded to phase 2 
compatibility yet.  Should this phase 1/2 jazz affect whether my a/ux
mac can use tcp/ip to other computers?        

Any suggestions are welcome.
