Hello
People plugs their laptops on our network, and dhcp gives them all tha basic connection data.
We want to disallow this behavior, and prevent unwanted PC's to obtain internet access.
How can this be done?
We are using windows 2000 server's DHCP

Thanks

Your problem is in the first part of your first sentence. You're REACTING
to the issue if you try to eliminate DHCP address assignments to rogue
computers. You should be PROACTIVE in your approach and establish security
for your LAN.

However, you can populate the scope with reservations which will eliminate
this but it will not keep them off your network with available IP addresses
if they choose to assign them manually.

I have the same basic problem. Using DHCP, how can i secure it so that only
authorized pc's get addresses, without going through reserving addresses,
( if your doing that, you might as well not have DHCP at all )
