Hope someone can help
I have a 2003 domain with 4 domain controllers. One of the domain controllers has been off line for about a yr now and I'd like to find a way to demote this server. Can I just turn it on let it sync up and then demote or is there a better way of doing this. Will turning this server on be a bad thing since it's been off for a year?

Thanks
 
Yes you can turn it on and it'll sync and then you can demote it.

That or you can delete the server from Sites and Services and it'll be removed from AD. You may have some DNS cleanup to do manually.

It should only take you about 10 minutes or so to do.

I doubt it will sync, if it's been off for a year it's gone past the tombstone lifetime which is either 60 or 180 days depending on whether the OS was installed without SP1 or had SP1 slipstreamed into the install.

Leave the server off and do a metadata cleanup;

Thanks for the tips but now it seems I have a bigger problem
I got to the step where I type "remove seleted server" and below is what I get

2 of the 3 current domain controllers have at least 2GB of C: space and the 3rd DC has 700MB, not sure where to go from here. Any ideas
 
When I first tried this I connected to a VM domain controller. Would it hurt anything if I were to start over and connect to a physical server rather than a VM server?
 
That could be really nasty, fair chance that a indicator of a corrupt AD database.

Try it from another DC and see how you go, the process should work on any DC bar the broken one.



 
Oh one question, just realized your have a DC running in a VM.

Did you build a new server and promote the DC or did you try some sort of migration physical to virtual.

(I'm guessing the later which is most likely the reason the AD database is corrupt)
 
You are guessing right(migration). So this morning I decided to try it on a DC that is not a VM and the process worked. Needed to do some DNS cleanup but things seem to be good now.
Thanks for you help
