Question: How do I troubleshoot a NIC?
The IT Guy says:
A NIC (network interface card) can be evaluated in several ways. If your computer is not connecting to the network at all: you cannot connect to the internet or any shared directories on network servers, you most likely have a protocol configuration error, a bad patch cable connecting you to the network port, a problem with the network port itself, or a faulty NIC card. A surefire way to determine whether or not the problem lies with the NIC card is to remove it and replace it with a card from another computer you know is functional. If your organization has the money, consider investing in a handheld network tester like those sold by Fluke Networks (www.flukenetworks.com). These expensive but extremely valuable devices can provide instant information about the performance and configuration of your network, and are invaluable for troubleshooting many networking issues.
