Realtek NIC running at 100Mb/s rather than 1000Mb/s

Realtek NIC running at 100Mb/s rather than 1000Mb/s My Realtek NIC in my Windows Home Server (essentially w2k3) box refuses to run at 1000Mb/s even if I change the driver settings from Auto Negotion to 1000Mb/s full duplex. I've installed the latest driver and tried changing the speed setting but I'm having no luck. Not sure what to try next. Any ideas?

"As others have already noted you need to be connected to a gigabit switch and, of course, there will need to be other gigabit enabled computers connected to that switch to get any practical benefit.

Note that if you are using a garden variety router/modem/switch it is almost certainly going to only be 100Mbit.

The other thing to be wary of is the cables being used. Yesterday I tracked down a similar problem in my own network where one of the computers would only connect at a slow speed. It turned out to be a dodgy Ethernet cable. You will need cables marked as Cat5E or, preferably, Cat6."

"Where do you plug the ethernet cable into?
Is it a switch/router that only supports 100Mbit/s? If yes, then that's the problem."
