Hello everyone,

since three weeks we've got some trouble with our Netware6 server
(running BM 3.6, GW 6.5, Netstorage as well): Every now and then the
server drops its network connections.

There's no backup, antivir or any other scheduled process running at the
same time... no hang ups, no abends
NICs set to auto-sense, tried force 100full/half, even 10 to no aveil.
Swapped ports at the router -> nothing.

at first, the auto-update feature of our antivir software tried
endlessly to connect to the internet and thus abended the server.nlm.
After deactivating auto-update nothing happens except that the GW MTA
and POA services shutdown after some hours.
Twice, the network link dropped until manually restartet via inetcfg.
Primarily the public network interface is affected (connected to a dlink
rp-114 dsl-router).

*My* first thoughts:
- replace Intel NIC with 3Com 3c905
- replace dlink RP-114

Any other clues?
Thanks a lot,
Tobias Mueller
