DHCP

HI!

Configuring DHCP on Windows 2003, how can I control who gets an IP address? because right now anyone that connects to a port gets an IP.

therefor you usally use a managed switch with port-security feature

you could try using exclusions in combination with reservations.
first define the reservation (therefor you need the mac adress of the pc, set lease duration forever) and then exclude all unassigned ip´s from the scope.

just an idee, i never tried that

You could try this.

Reserve all the available IP addresses in your scope with a dummy mac address (00:00:00:aa:bb:cc)

Then assign only the real mac addresses that you want to get an IP.

I hope we're talking about a small subnet because this would be a lot of work to manage.

Exactly, the lan is not small; more or less 3,000 persons; could the users be validated by the active directory?

 

[VoIPP]

could the users be validated by the active directory?"

Well... in order to be validated they would need an IP address.

You could use the DHCP server callout dll, basically you have a text file with allowed mac address in it and any mac not in the text will not be issued an IP address, this feature is now built into 2008 R2 but there is a download for 2003 and 2008
