I've got Windows 2000 Server installed on one of my machines. It's a recent install and only has necessary stuff on it. IIS, mDaemon, and NAV 7.0. Recently the "System Idle Process" has been taking up between 50 and 90% of the CPU Usage when I don't think it should be! I ran hijack this on it and everything looks like its ok. If I physically unplug the network cable from the computer then it goes back to normal. I'm behind a linksys router/firewall and a cable modem connection. I have the necessary ports forwarded to it for WWW and mail but even if I unforward all ports it still has high usage. If I disable the network connection I get the same as unplugging the cable. The NIC is a Linksys EtherPCI Lan Card II and the light on the back is constantly flashing. Anyone have any ideas?
