win2k seems to be causing ethernet CRC errors

In a review of the interface counters on the switches where our servers are
connected, I noticed one of our win2k sp4 servers running SUS was
generating CRC errors.

I tried changing:

1. the patch cable
2. the switch port
3. the ethernet port on the server

This still did not fix the CRC errors. So I figured it must be something
wrong in the server ethernet controller, etc.

I pulled the drives from that server and put into another server, used
different patch cable & plugged into different port on the switch.

guess what? I'm still getting CRC errors from that server. I can only
conclude it must be software. What in win2k could cause this? anyone?

Nothing of the OS is likely doing this. Drivers for the NICs MAYBE,
the NICs, the switch itself probably.

It's a hardware problem most likely and it sounds like the only thing
you didn't switch was the switch <grin>

Also, it might be another machine on the same leg of the switch but
it sounds like you covered that with a different port.
