Here is a strange problem we are having.  We have a MOD80 with 2 trns and a
3c523 ethernet card. The server will at times stop broadcasting the network
numbers on its side of the ethernet. For example:     
OUT [00004831:ffffffffffff]   00005004  1/2     00001005  1/2  
    00001006  1/2

does show up on the track listing. 

only this shows up:

OUT [00004831:ffffffffffff]  SERVER1  1   PSERVER1  2    PSERVER2  2

which is only the names of the server and print servers on the server's 
side of the ethernet.  The ethernet is a backbone and connects server1 to 
the rest of our servers (WAN).

The problem that this causes goes as follows:

Other servers that try to attach or login to server1 stall for about 30 sec.
and return with a message SERVER1: No response from file server. Also when
using a workstation hanging from one of server1's trns, you get the same 
no response from file server trying to attach or login to the other servers. 
Also, server1 shows up on all the slist of the other servers and on all 
the display servers. The problem, we think, is that the OS is for some
reason not broadcasting the network numbers, just the server name. So the
other servers see that server1 is there, but they do not know whats it's
network number is, and how to route to it. The ethernet does seem to get
all the IN's however, so we are not really sure. It doesn't seem to a 
problem with the hardware (like the ethernet card, the transciever cable,
or the transceiver. It it was a hardware problem, the stuff would show 
up on the track, but the problem would exist.

HELP!!!!

PS: keep in mind that this occurs every once in a while, and the problem 
fixes itself while the server is up! Rebooting the server will not fix
the problem!

Please respond asap with any suggestions.
