Be careful re-using IP addresses on DHCP servers. We had a problem getting a DHCP server to *REALLY* be authorized when we re-used the IP/name. I don't remember the details, just that we had problems with it - your situation sounds similar enough that you might want to try de-authorizing the server and re-authorizing it to see if that helps. -Brian

Right now it's only configured with a single scope for a different subnet, but the clients on that subnet keep going back to one of the two original DHCP servers. Would ISA2004 require some type of entry allowing DHCP requests to go to the new machine?

It's handling AD and DNS fine. It's also configured as a DHCP server with subnet scopes split about 60/40 with an existing DHCP server and can be managed via the DHCP Admin console. However, when clients try to renew an address they never hit this new DHCP server, even if it's the only one available. How best to troubleshoot this?
