Yes it can.

In your DHCP manager, click server|add then input the IP address of the new server you want to add. You can then administer it as normal.

Of course the DHCP service must be running on the new server.

Hope this helps

Steve.

A single DHCP Server can handle multiple subnets.
The key is getting DHCP requests from the other subnets over to the subnet your server is located in.
Most routers have a form of DHCP helper setting. This passes DHCP requests on the other subnetto the DHCP server. The DHCP server will return the request will an address from the proper subnet. This is because the DHCP helper adds additional information to the DHCP request indicating the originating subnet, letting the DHCP return a valid address for that subnet.
If your router doesn't support it, or you dont have adminstration rights to the routers, you can use a single NT system (workstation or server) and add the DHCP relay service. This does the same thing as the DHCP helper on a router.
