DHCP Setup and Replication between two AD 2000 servers.

I am running Active Directory 2000 on two Win 2K servers.  We already do DNS in Windows and I want to move DHCP to windows to simplify matters.  I have installed DHCP on one of the AD servers.  But I thought there was a way to setup DHCP so it could run on both my AD servers and replicate between machines.  That way if one of the AD servers is down the other can answer the DHCP and DNS request.  Since we have DNS doing this (I did not set it up) how do I get DHCP to do this?  Is it just as simple as install it on both AD servers and it works?

Thanks,
Louis

So in short that paper is saying you install DHCP on both ADs and then setup a SuperScope that covers scopes on both DHCP server?  Not really sure how I setup a SuperScope that does that.  Guess I will have  to just install and try.

Louis
No need to set up superscope. Create two identical scopes on both DHCP servers, add exclusion range for 20 % of address pool on first server and add exclusion for 80 % on second server. Available addresses on both servers should not overlap. 80:20 is reccomended ratio, yu can use 75:25 or 50:50 also.
Ok that makes more sense.  And I am going to guess that this is where the option for "Conflict Detection Attempts" comes in to play???

Louis
If address pools do not overlap, this settings should be configured to zero. When one of DHCP servers fails, you should remove exclusion range from it and set Conflict detection attempts to number greater than zero. Now the remaing DHCP will check, if IP number is already used before will lease it to client.
Excellent...  Thank you very much for your help...
