Demoting a 2nd domain controller

I have a 2ndry DC that needs to come out of service to be reformatted. Dell only put a 12 GB partition on it. As of now it is working fine and DNS is pointed to itself since replication has been fine. Should I point it back to the primary DC DNS or is it ok pointing to itself before DCPROMO to demote it? Also its a global catalog server now, should I uncheck it first? Do any records need to be cleaned up after in DNS?

It is ok to point to itself before demotion and you don't have to uncheck the GC first.
The DNS records should all be cleared during the demotion.
You will need to manually delete the server from sites and services.
So right now you only have one 12 GB partition or is there another drive (or RAID set) there also?
Thanks

Its a RAID 1 with a 12GB C drive and and a 148GB E drive. They made a mistake and put that configuration. I wanted one 160 GB RAID 1. Will I need to make a new site or will the new 2nd DC go to it since its on the same subnet?

It should go to it because it is in the same subnet.
You can also move the AD files to E if you wanted to http://support.microsoft.com/kb/816120
...but if your ultimate goal is 160 GB RAID 1 then you have to do what you are doing.

ok so let me repeat the steps, DCPROMO is down, remove the old one in sites, add it back to the workgroup, reformat the drive, install DNS, DCPROMO, make sure it went to the proper site and make a GC server again?

Yeah that should be fine, after reformat and rebuild of the array you install Windows...of course I knew you would do that.
Thanks
