Just been having a poke around DNS as part of planning for Exchange 2010 where apparently you need to set up coexistence records for a legacy.domain.com address.

Then noticed loads of NS records in the forward and reverse zones... many of which are dead servers and one of which is pointing to our website URL?

Doesn't seem to be right to be having those in there so was thinking to remove any that aren't active DNS server hosts. Before I do though is there any logical reason they could be there?
