Hi folks.

I have a Windows 2003 server and I want to set up DHCP on it so that only people with a pre defined class id on thier client can get an address from it.  Now I have set up a Class ID on the server called test, and the client is set to class id test.  That works fine, it get an ip address and options from that server now, but so do other machines that do not have their class id set on the client.  How do I stop clients from getting an address from this sever without using mac addresses.

If you want to restrict users from getting IP addresses, I suggest you get a manageble switch that tracks the MAC addresses connected to each port and then use MAC layer restrictions on the ports on the switch.  This way even if a user gives himself a static IP, he/she will not be able to gain access to your network.

Sounds like you have taken the correct steps, but have a look at the following to see if it adds anything you may have overlooked in your configuration:
"Use DHCP Class to deny Internet access to unauthorized machines"
