random disconnects

[Frank Butler]

Greetings;

Please forgive this newbie if I have posted to the wrong forum. I
have a NetWare 5.1 server, fully patched (PIII 866, 1GB RAM) with
GW5.5 fully patched. I get random Notify disconnects, random client
disconnects, 820e errors on the POA screen and a myriad of other
"connection" related errors. I am including a snippet of the POA log
(verbose) and I am wondering why I see users login in to GW with the
same IP address.

I have replaced all network cabling, ran every conceivable GW check
for database inconsistencies and have come up clean. I am starting to
suspect a NIC in the server or perhaps a switch (relatively new
3COMs). I also get a fairly alarming number of "carrier sense
missing" errors on the Monitor screen on the server as well as d109
errors on the POA. I am running out of ideas so any help would be
appreciated.
