I have a Dimension 4550 that I replaced the hard drive in. This computer also has an Intel Pro 100M Integrated PCI NIC card. After raplacing the hard drive, I cannot set up my LAN or connect to the internet, and the Network Setup Wizard says I need to install all the hardware first. I have replaced hard drives before, but not on a machine w/ an integrated NIC card. What do I need to do to get the NIC card recognized and get the network set up?
