Slow Network Speed
-
I have a Windows 2000 server with 15 workstations connected to it via a domain. The server has 2 Network cards both Intel Pro 1000 MT Gigabit Ethernet Adapter - Onboard. The network speed used to be 1000.0mbps on each card but suddenly fell to 100.0mbps slowing the entire network. What could be the cause and how can it be rectified? The server is a Dell.

One/both of the cards are defective? Have you tried re-booting it? Have you looked at each NICs properties and made sure that the speed is either "auto" or "1gb"? On-board NICs have always been kind of flaky (regardless of what motherboard you might happen to mention). If it's a Dell, I'd contact their customer disservice department. For what it's worth, I disable on-board NICs and insert add-on cards. This way, a repair consists of replacing the add-on card instead of completely dismantling the system itself to replace the motherboard. Besides, it's cheaper to maintain a supply of spare NICs than a supply of spare motherboards.

You must have a switch / router in the network, you haven't recently replaced / reconfigured it have you? Have you tried connecting a workstation directly to the server to see what speed you can get?

It's a copper network, right? In that case, check the cabling as well. 1000 Base T uses all four pairs, and if auto-configuration is on, damage to one pair can cause the network to fall back to 100 MBit/s.
