HP Proliant ML350 Stops Communicating On My Network

I have an HP Proliant ML350 server which serves as a domain controller running Windows Server 2003 sp2.  About once per week it stops communicating with my network; when this happens I cannot ping the server by IP address from any device, and I cannot ping any other device from the server despite the fact the connection status on the server shows it is connected at 100Mbps.  I have installed the latest HP support pack which had no affect.  I tried repairing the network connection at the time it stopped communicating and it cannot complete because it errors out while attempting to clear the ARP cache.  Finally, I thought I found a solution when I read a forum thread talking about 'Routing and Remote Access'  creating this type of problem.  The routing and remote access service was enabled to allow dial-up access at one time but it is no longer needed so I disabled it about two months ago and the communication problem appeared to stop, until yesterday when the server lost communication again.  I tried repairing the network connection, this time with the routing service disabled and the repair succeeded however the server still wasn't communicating.  The only way I have been able to recover is to restart the server and then it is good for awhile until all communications stop again.

Hi,

have you tried to reset the TCP/IP stack after hours?

what do the event logs say?
I have had a similiar issue - only happened a couple of times though and never found out why it happend. It's not a solution, but the workaround for me was to disable and reenable the network connection. This way at least you don't have to reboot.

g000se: I have not reset the TCP/IP stack.  I will schedule a time to do that and give it a try.  The event logs show nothing relating to this problem.  As I go through the logs I see where I restarted the server and no errors precede that entry.

Wonko_the_Sane: I did not try disabling & enabling the connection but if it happens again before the problem is resolved I will give it a try.  I repaired the connection but in the heat of the moment when I had a lynch mob standing outside my door holding a noose...  I wasn't thinking clearly.  :)
Also when you reset the TCP/IP stack you will need to re-enter your IP address information after rebooting the server.
Does the server have multiple nic's?  If so, Are they teamed?  
I have seen that before and there is hard to fix the issue. You may need to run Windows Repair install:

- Backup image of your server
- Run repair install: http://support.microsoft.com/kb/325375
- Reinstall SP2
- Reinstall HP PSP

It will be awhile before I know whether or not the TCP Stack reset suggestion works so I am going to give credit since that was the best suggestion.  I have since had a power issue on the same server where the server was powering on for 2 seconds, then off for 2 seconds over and over and I wonder if this is related to the original problem I am having.  HP support suggested re-seating the power supply backplane so I will try that as well.
