Event 1291

I have some HP servers that unexpectedly get rebooted and loose their static IP address.
I checked the event logs , and in addition to the "shutdown unexpected" event log, I found the Event 1291 Source: NIC Agents.
it says "NIC Agent: Connectivity has been lost for the NIC in slot 0,port2 (SNMP TRAP:18012 in CPQNIC.MIB"

Any expert out there, please to explain whay this is happening.
The OS on which it is happening is Windows 2003 servers

I found this link:

it says:
User Action: Check the cables to the adapter and the Hub or Switch. If no cable problems are found, the adapter, Hub, or Switch may need replacement.

But in my case, it is happening to some HP servers that are in different switches.
I cannot blame all switches.

I have seen some comments on the internet where they say when you have 2 adapters but only one is connected, then disable the one which is not connected, because when the server reboots it tries to provide an IP address to the adapter which is not connected. It didn't make sense to me.

I don't even know what caused the reboot. would NIC problem cause the reboot?

In order to isolate the server issue from the switch issue.
I am thinking about disconnecting the server from the switch then reboot it  few times and see if the server will keep or loose the static IP.

if it looses it , that means the issue is from the server [either the NIC, or the drivers,or I don't know...]
if it keeps it then I will reconnect the server to the switch and give it few reboot and see .
