Hey Everyone,

I was wondering if there is a way I can make a
replication of the DHCP from the primary domain controller
to the secondary domain controller. If there is, how can I
do it ? Any suggestions will be greatly appreciated...
THANKS in advance...
 
You probably can, but the main question is "why"? There may be an easier
way to accomplish what you need..

One uses a dhcp relay to extend a dhcp's area of lease distribution accross
routers, one does not replicate a dhcp server and cause ip lease conflicts
to occur on the network. Since there is no such thing as a PDC and a BDC in
W2K, why are you asking your question here?
 
Hi,

There is not a mechanism for replication of a DHCP database. If you try
using the same DHCP database on two servers you will end up with IP address
conflicts.
If you simply want to move the DHCP database from one server to another you
can use netsh.

It's one of those things were you have to put yourself in his shoes.

It's not about having two DHCP servers doing the same thing, it's about what happens if you lose the primary dhcp server and don't have a second one running half the scope.

For instance, I want to be able to have a failover situation where if one serer fails I can just turn on dhcp on the other box. Easy enough would be to have a second server with dhcp installed but not running and copying over the DHCP backup folder (The default automatic database backup interval is 60 minutes.) So if there is a script that copies that folder every hour or day or whatever.

c:\windows\system32\dhcp\backup

Then a restore is all you have to do to get the new dhcp online. Just don't forget to either add the old ip to your new server or change all relay pointers.
Also, the backup contains the leases so you won't have conflicts.
