I am stumped. I have two machines on a Cable/DSL Internet Gateway/Firewall (D-Link DI804).

First machine (Name: Carbon):
(2xPIII-933, 2GB RAM, Motherboard: Abit VP6, Running W2kPro) is connecting to the net at ~6 kbytes/s

Second machine (Name: Boron):
(PIII-500, 512MB RAM, Motherboard: Tyan S1854 Trinity 400, Running W98SE) is connecting to the net at ~90 kbytes/s.

I have switched ether net cards (Linksys LEN100TX V4.1) and it makes no difference. I have replaced the driver with the latest one from Linksys for V4.1 and W2kPro. I only Components that I have installed are: Client for Microsoft Networks, File and Printer Sharing for Microsoft Networks, and Internet Protocol (TCP/IP). I even took the Ethernet cable that was in Boron (while it was connecting to the net at ~90 kbytes/s) and connected it to Carbon without making any other changes and Carbons connect speed was still a dismal ~6 kbytes/s. When I moved the Ethernet cable back to Boron it again connected to the net at ~90 kbytes/s.

I talked to Linksys tech support and they could find nothing wrong with my configuration. One thing that we tried was for the device [Linksys LNETX Fast Ethernet Adapter (LNE100TX v4)] Properties/Configuration/Advanced to change the media type from AutoSense to 100Base TX Full_Duplex, but that made no difference, or If any thing it made the situation worse.

I tried changing PCI slots for the Network adapter in Carbon but that made no difference either.

While my connections have been dropping or timing out on Carbon; Boron is fat dumb and happy. When I can't connect to the Internet at all from Carbon; I can surf as much as I want from Boron.

If you will respond directly to me I will post a summery of responses containing the results that I obtained from trying the suggestions.

Thank you,

This may be a frusrating piece of advice, but I had the same problem and solved it after months of search. Apparently, windows 2000 does some kind of unneccesary system scan everytime it searches a network which in turn causes the slow network access. This can easily be remedied with the deletion of a certain registry key.
And now for the annoying part: I forgot where the key is. I know this sucks, but i'm sure some website will have it... just search google with the necessary key words.

good luck =/

Try re installing the OS it must be the OS thats causing the problem that or the driver
