Secondary DHCP server

I have a network that currently has two domain controllers.  One is a Windows 2000 server and the other is a 2003 server.  I am planning on replacing the 2000 server with a new 2003 server, and then both domain controllers will be Windows 2K3.

Currently, all of my DHCP requests are handled by the 2000 server.  I would like to split the DHCP requests up between two servers and so I installed DHCP on my 2003 server.  I configured identical scopes on the 2K3 box, and then made exclusions on each so that the two servers don't overlap.  The 2000 server is set to handle addresses from to and the 2003 server handles to

My problem is that when I start the DHCP service on the 2003 box, the DHCP service on the 2000 machine seems to go down.  Is there a reason for this?  Is there a setting I am not seeing or performing?

Are they SBS servers.  I think SBS only alows 1 dhcp server.  If it detects another it will disable itself.
There should be a message in your event viewer with an error along the lines that it detected another dhcp server.

If they are not sbs server are there any errors in the event viewer?

The 2000 server is a SBS.  I haven't had a chance to check the logs yet, I'll do so in the morning.  I did not realize that SBS only allowed one DHCP server.

You should really only have one DHCP server on a network. Have DHCP running on one or the other. If you would prefer not to select one of the servers for whatever reason and you have a router on your network use the router as the DHCP server while you move from one server to the other.
Are both DHCP servers authorised? This may cause the issue.
As for running two DHCP servers, this should work. The server that is first to respond will provide the IP - may organisation run two for failure over - the spilt is usually 80%-20%

That was the problem.  I didn't realize that SBS only allowed one DHCP server on the network.
