Network card disabled, all by itself

[Bozz]

I look after lots of small peer to peer LAN systems and occasionally one of the PC's will disable the network card, which is a big problem if that's the file server. This is a pretty infrequent occurence but annoying never the less. I have disabled the option to allow the PC to turn of the device to save power on one that went off today but, as this is so infrequent I'm not sure if that is the cause. Any ideas out there?

Bad RJ45 connector contact. Dust in ports

Mis wired or out of spec cable. Don't trust cheap network cable testers.

Excessive errors at NIC or switch port. If you have a managed switch, check out the port info.

Re-seat the NIC card, in the server.

Uninstall the NIC and replace it with another NIC.

Poor driver or resource sharing problem such as poor IRQ sharing. Sometimes you can jockey the NIC IRQ to another in the bios.

Disable power management in the server bios.
