How to remove dead DC from AD?

Hi Guys

I had two DC windows 2003 SP1 servers say server1 and serve2. I trashed one DC “server2” not knowing that it was DC. Server2 does not exist any more (can’t bring it back).

I prepared another server Windows 2003 R2 call it "server3" and I want to promote server3 to DC.
When run dcpromo command I got error message "The version of the active directory schema on the source forest is not compatible with the version of the active directory on this computer" this computer being "server3", and asked me to run adprep command
So to achieve this first I've to prepare server1 i.e extend the schema on server1 (Win2k3 SP1 and server3 is windows 2003 R2).

Correct me if I'm wrong!

When I run "adprep /forestprep" on server1 (Win2k3 SP1) I get message "The schema master did not complete a replication cycle after last reboot. The schema master must complete at least one replication cycle... ."

Problem is
1. I cannot delete the server2 object from AD using "Active Directory Sites and Services"
2. I only have one DC and am concern that I might loos it by doing something wrong.
3. I read MS article Q216498 but it confused me

Is there better way promote server3 to DC? Or how do I promote server3 and add in exsting domain?

Thanks in advance

with windows 2003 R2 (release 2) you will need to run the adprep tools from the second cd supplied in the 2 cd set!


you can also download more details here

this boosts the schema up to cope with R2 functionality

to remove the DC follow this (all the way to the bottom)

also, i would run a dcdiag on the current DC before proceeding with a new addition
