My restore has been successful and I'm back to square one - a clean 
single DC not trying to replicate anywhere.
The only place I can still see DC2 being referred to in Active Directory 
Users and Computers -> Domain Controllers.
When I try to delete it from the list I'm presented with attached prompt.
Is it safe to proceed and try using Windows AD tools to complete the 
cleanup?
