Network Card for a server

My Compaq Proliant 5500 server sits in a remote hosting facility where every few months or so a Network card on the box dies...It could be a motherboard issue, a spike  at the hosting facility causing the issue...
I've used 3com and compaq so does anybody recommend a more stable card?

How about checking for voltage spikes on the network cable?  They make surge supressors for network lines, I'd suggest trying one.  In my opinion, 3COM network cards are first rate.  In fact, I've NEVER had one fail on me that I have some that are now close to 10 years old!

I agree:  Definitely not 3Com's fault...

In addition to the supressors for the LAN line:

What kind of power conditioning does the server have?  Something shared with the facility?  If so, I'd seriously consider getting a good conditioning UPS just for your own machine even if the facility has a comprehensive power conditioning system.  They don't really cost much compared to your server's purchase price, and add a nice level of reassurance.

Is this peculiar to just your machine or others as well?  If other machines are suffering similar problems then it is the hosting facilities fault.

The suggestion has been made that it is a network cable spike fault.  If it is affecting yours then it should be getting others as well.

If it is only your machine that is getting affected then I would start suspecting your machine has a fault in some way.

-yup

Although you have not answered q's on other equipment, I say move the server.  Too many buildings are miswired, and as a remote, if card is fried, there is too much to not trust. With little to go on, I say move. UPS is nice but won't help this.

But is card really dead... As people upgrade and get new switches and up speeds from 10 to 100 they forget things in mixed environment. Some cards do not duplex well, same for switches and hubs at 100. I suspect your environment has too many mixed pieces like NIC + hub + server etc, and that they are interfering with each other.  Try for a more isolated environment, at least for your equipment, and have everything on your switch configured same. If must, find admins for other boxes to get concurrence, which should be likely as they have similar vested interest here.

I have heard some 3Coms can cause such problem, but like those above, it is not my experience. 3Coms for me have always run better than alternatives like SMC or tulip.

It will, actually, even my $200 APC will sound an annoying alarm if the building's wiring is not properly grounded, etc.

Thanks for the input...To give a little more info, the server has two Network cards, and the card in question is the second network card. The primary purpose of this card is to connect to a third party backup solution provider (storage Networks). The NIC cable connects to a cross connect patch panel in one cage (we two cages in this hosting facility)and in the secong cage a Cat cable is connected to the cross connect patch panel to a Cisco 3500 Cat switch. The switch then connects into storage via fibre cables...
My inability to ping the switch from the server has happen twice in the last 2 1/2 months...Each time this issue has ocurred, i still see a green connection light on the switch.

I take it you've tried the simple things like a new cable?  Maybe someone accidentally stepped on/twisted the old one and it has a short?  For $29, I'd still start this fix with the RJ45 surge suppressors.
