Had this happen to us about a year ago and it
turned out to be a bad network cable.

Geza,
Maybe this is too obvious, but I
have never seen anyone mention it. In network connections, for each
adapter, click properties. On the General tab, click the Configure
button for the adapter. Click the Power Management tab. Ensure that
"Allow the computer to turn off this device to save power" is not
checked.

A strange thing is happening with our email server
for months now and I am getting fed up with it, so I decided to get to
the bottom of it.
The Imail server v8.22 (W2k server with SP4) looses its networking in
average once a day or every other day. What I mean on loosing is that
for example when I get a time out error on the email client, I do the
following on the Imail server locally:
At a command prompt I type ipconfig/all, = all settings are OK.
I pinged 127.0.0.1, replies OK
I pinged the IP of the default gateway, it's timing out and if you ping
any other IP, the result is the same.
I looked at the event logs, no error in it that would give me a clue.
If I reboot the server, everything is fine for another 24 hours.
Our Imail server receives mail through Postini, and the firewall has
been set up to allow smtp 25 traffic only from Postini servers. based
on the log file, our email server receves 1500 messages a day average.
So, what troubleshooting steps do you guys recommend for this
particular problem?
Until I find out what is the problem, what services related to tcp/ip
networking I could restart on the server that would substitute
rebooting the server?
