Proliant DL380 G5 NIC loses gateway address and connectivity

[jgs]

I have several Proliant DL380 G5 servers running Windows 2003 R2 x86 at my work, and I have noticed at random (twice a week)that some servers are losing their gateway ip address when running 'ipconfig /all' from via 'cmd'. As a result, these servers cannot be contacted until the NIC is rconfigured from 'Network Connections'. The operational NICs are NC373i (driver version 2.8.13.0) and NC360T (driver version 9.3.39.0) and the HP Network Configuration Utility (version 8.40.0.24) is installed. The NICs are patched into CISCO 3600 Gig switches operating at 1Gbps.
The NICs were even teamed to rule out a faulty NIC, but the symptoms still exist.

Has anyone experienced similar issues and found a fix?

did you find a solution to this gateway address lost problem?
we have the exact problem.
If I do a arp -a command, the gateway mac address shows 00-00-00-00. It seems to fail more frequently every week.

I believe 2 gateways were configured on the server. The solution was to remove one of the gateways.
