I have several Compaq ML370 servers, connected to different switches.  These servers have Intel integrated nic cards.  If I go to statistics, I see a large number of "transmit underrruns" and "transmit overruns".  About 4500 in the last week.

What could be the issue here?  The switches are seeing CRC errors coming from these machines.  Is there a certain number of errors that are within an acceptable range?

Lock the NIC into a proper speed.

If your switches can handle 100 full-duplex - lock the server NICs to that speed.

Autonegotiate is not foolproof and does have inconsistencies between manufacturers.

Currently, all the network adapter cards are set to 100 full, as well as the switch ports

just a suggestion that didn't involve much thought...

have you tried updating the drivers (or checking for new ones, at least) for the nics?

very basic, but i wanted to throw it out there.
