I'm looking into this now but here's what I want to achieve.

Scenario: Small office, 6 people, 1 workgroup. Windows 2000 server acts as DHCP and DNS server, also as a router to the internet. They have a 4mbps connection to the internet.

Problem: When someone starts a big download or downloads a big e-mail attachment they seem to take most of the 4mbps intrernet connection and everyone else crawls along. I can find no way of overcoming this....so far!

Solution? I really want to limit a users bandwidth so that everyone has a fair share. Is there any known way of doing this or software that can help do this by mac address for example?

Any suggestions welcomed...
