Hello,

We have two active directory domain controllers. The older unit has completely failed and is unrecoverable. This has caused a problem. How do I remove this failed unit from the domain so the domain stops looking for it.

Thank you

Hi,

you need to perform the metadata cleanup of you active directory.

After that just to make sure double check the DNS and Sites & services and remove records related to old DC.

Make sure you also Seize any of the FSMO roles that the Failed DC was holding over to the good DC.

The servers are running Server 2008. I followed the directions as best I could and seized the FSMO roles. I also went through the DNS manually and deleted any records that had the old server name.

I followed the server 2008 metadata cleanup commands and it worked great. The slowdowns are gone.
