I'll compare the result from an ifconfig -a next time I have this problem 
like Duc suggests and try stopping and starting the interface. Strange 
thing is it happens to all of the unix stations, not just one of them.
The local VT100 works fine, also the stations continue to work fine, no 
blue fields.

I'm investigating another possible cause for the moment, Global IT has an 
EPO server scanning all connections to the LAN, and since our unix 
stations are also connected to the business lan, the ports may get blocked 
by the scanning or after the scanning took place for some reason. We took 
out the unix stations' IP adresses in the EPO servers scanlist so they 
won't get scanned  anymore, see what happens....

Thanks for the help guys,

Dirk,
Did you have local access to the stations? I have experienced the same
problems on a 6.3 system where the station ran out of processes (eg: 
cannot
open a new VT100).
The station would appear to run fine, except no new process or connection
could be started. You can run "sar -v 1 2" to see the number of processes
and "ps" (with options) to investigate.

If it's only a connection problem, you should try stopping and starting 
the
secondary ethernet interface locally and see if it that resolves the
problem.

Hope this helps,

Maks Wilde
