Recently i decided to add a secondary DC since the one i have is a virtual server, I did DCpromo (Both Running Server 2008R2) went thru all the normal steps, DNS is working flawlessly, AD is also working Fine, DHCP is the one thing that did not replicated or at least it didn't let me do the 80 20 balance Microsoft guide said is best practices, i cant seem to figure out how to remedy this any help would be grateful.

You will need to create the DHCP scopes manually on 2008R2. When creating the scope, assign 80% to one server and 20% to the other. Let's say your scope is 192.168.0.0-255

Assign that scope to both servers but in the addresses to hand out configuration - set the 1st server to .X-.200 and the 2nd server to .201-X

I used .X above because you may start your scope at .2 or .10 or whatever. You also may end your scope before .254

DHCP does not replicate - as said earlier, either you can create a split scope or a fail over cluster. The configuration requires to be manually done.
