Hi all,

I have a server that sometimes loses connetion with the network without
apperent reason.
Last time the server lost connection there were no activity on the
server and after a restart connection where up and running again.
After a few weeks the problem comes back.

Can it something wrong with the network card?

I would start by looking at the Event Viewer.

OK!

This is what I have:
=================================
The Security System detected an authentication error for the server
DNS/dns1.MyDNS.se. The failure code from authentication protocol Kerberos
was "There are currently no logon servers available to service the logon
request.
==================================

The system failed to register host (A) resource records (RRs) for
network adapter

with settings:
Adapter Name : {DDCD65F0-1AA7-4019-BBD2-F65CC8A7DA49}
Host Name : MyServer
Primary Domain Suffix : MyDns.se
DNS server list :
xx.xxx.xx.xx,xx.xxx.xx.xx
Sent update to server : <?>
IP Address(es) :
xx.xxx.xx.xx
==================================
... and after a restart everything works fine.

I suspect you have a dud network adapter, as you already suggested
at the beginning. Try a different adapter.

Well, I thought that first.
But: "The Security System detected an authentication error for
DNS/dns1.MyDNS.se....There are currently no logon servers available"
....doesn't that tell the problem is outside MyServer?

Don't know. If this was my machine then I would check Google
to see what exactly causes this message to appear. I suspect
the message is the ***result*** of a network failure, not its cause.
