I have 2 domain controllers (they're OS was Server 2003) that are no longer existing on the domain--for years and are long gone. The sites that they were associated with are no longer existing, so they have no site assignment. I am prepping to upgrade the domain and forest level from 2003 to 2008. I only found these domain controllers by querying the list of domain controllers using the "nltest" command line. If I go to the Raise the Domain Function level and save a log file for the domain controllers, these two servers are NOT listed as servers that need to be upgraded.
How do I clean these orphaned domain controllers from my Active Directory? I tried the Metadata command but it requires to choose a site, and these domain controllers do not have a site assigned.
