Connection to Lan fails and locks server

Morning,
We have two nodes in a sql cluster. The "Lan" connection on one of the
servers fails at different times and I can't track down the problem and I am
not sure where to start.
I have changed NIC's Cables, Switches and still no luck..
Any suggestions where to start would be appreciated.
Thanks
Firmware? BIOS? Drivers? Called the vendors?
Cheers,
Rod

|||Actually we had a DELL rep come out and set this up because we did not want
to mess with the SAN LUN's. He couldn't figure it out either. I will take a
look at the BIOS. We are running a Win 2003 with sql 2000 cluster.
I noticed earlier that Network DTC was not installed on both servers so I
installed that see if maybe that will make a difference.

To ask the obvious... SP3a installed?

|||SP3 A is installed. Server failed again after 3 day. Network cards pass all
test? I will post some logs see if anyone has seen it before.

have had this problem for 3 weeks now, the amount of time it takes to fail
varies. Any help would be appreciated.
