Hi all,
We're using telnet to get to our library computer.  Lately, at one library
only, we've been seeing quite a few sessions just dropping at the client
end for seemingly no reason, most times after large periods of inactivity.
This is happening with W2K and W98SE stations, but not all machines in
the building are affected.  I stuck a packet sniffer on one machine, and
found out that the MAC address changed at the client end, then the host
immediately sent a RST (reset) packet and dropped the session.  The previous
telnet packet looked fine.  They are loading Novell as the primary protocol,
but also TCP/IP.  This has just started recently (last month and a half).

Has anybody seen anything like this?  I'm totally at a loss.  -George
