Losing connection to Windows 2003 server

I have started having a problem over the last week where I keep losing
connection to my server. I use an application that is on that server and
every so often it says I have been logged out. When I try to log back in, I
cant. I try to ping the server, I cant. I try to RDP into the server, I
cant. This continues for a few minutes, and then I can get back in. It
seems almost as though the server had been rebooted, although there are no
entires in ANY of the event logs. I have done malware and virus scans, and
nothing is found. I have changed NIC's, thinking possibly that one of the
integrated NIC's is going bad, same problem with both NIC's. It isnt just me
that has this problem, when I am kicked out of that application, nobody can
get to the server. Once again, it is a Windows 2003 Server SP2 with SQL
Server 2005 installed. Does anyone have any ideas?

Thanks in advance!

I would wonder about wiring / switch port / IP conflict.

Can you rule any of that out?

Are you pinging by name or IP?

I will try swapping out ethernet cable and then put on another port in the
switch, but if it were an IP Conflict, wouldnt I get something in the system
log?

I have tried pinging by both name and IP, same results.

One would think...

Ok.

So it's not a resolution issue.

Keep looking towards the physical or possibly some sort of filtering.

Possibility also that the RSS/TCP Chimney feature may be causing it, or even
IPv6.

Would the server come back on line like the OP is saying happens?

A quick glance at the link you provided leads me to believe that a
reboot is required for the server to come back on line if it's a RSS/TCP
Chimney problem.

Hard to say. I remember one installation I had this problem with was when we
rebooted the server, the connection would be active again, then after
awhile, connectivity would be lost. It was evident between an Exchange 2007
and two 2008 DCs. I actually had to call PSS on this issue as an initial
DSAccess Outlook Anywhere issue. After four hours and PSS conferring with
their AD group, they came up with a solution to disable IPv6 (in the NIC
properties and reg) and disabling RSS/TCP Chimney in the reg, rebooted and
haven't had a problem since. That was 10 months ago. I came in on that
installation after the fact, so I can't attest what happened prior to that,
as in what was installed, removed, etc, but I haven't had that problem with
any other Ec2007/AD2008 installation that I've setup.
