Restricting DHCP Access
Is there some way that I can prevent someone from plugging into my network and getting an IP Address, but at the same time allow RIS clients to get IP Addresses when they need them? I'm the only one that uses RIS, but it would be a pain in the ass to have to enable DHCP every time I wanted to use RIS. I'm tired of people plugging their laptops into the domain subnet though, so I want to prevent them from getting IP Addresses. There are about 35 domain machines, and 2 servers running W2k3. There is a seperate subnet that is for wireless and wired personal laptops.
You can use reservations for the clients that are allowed to receive a DHCP address, then simply exclude the rest of the range.

how would that work with RIS? The machines I use with RIS aren't the same machines that are on the domain. They are machines I bring in to work on.

Oh, and I don't have a managed switch for mac address filtering.
As long as you have the MAC addresses of the machines (and they have reserved addresses in DHCP), there isn't a problem.

I don't have the MAC addresses of the machines I'm going to use RIS with. I suppose I could get the mac addresses before I ran RIS and add them to the reserved list?

It keeps giving me warning in the event log about the scope being full. Can I stop it from giving me that warning all of the time? It's really starting to flood the logs....
Unfortunately, I haven't found a way to get rid of that; I've been looking fort that myself. It's majorly annoying, I know ...
if you have a switch that they plug into you can do mac address filtering.
Hope This helps
