Old DNS Site


Our busines sused to ahve a second building, and a second DNS site. This was lett some four years ago.

I still have the site in Forward Lookup Zones under DC site and GC site leaves.

Can I just delete these, or am I meant to remove then somehow? They are 'orphaned' so may be difficult to amdinister. Hence my sdeleteion question.

Yes remove it.

Was that DC Server demoted or just taken out?

If the DC is still in Active Directory

Look at this

Presumably you still have access to the PDC?
Removal of DNS entries should be the last thing after a couple of other checks...

1. If the remote server is also a secondary DC then you really ought to demote it first otherwise you can end up with an unclean removal which can then remain as an orphan lurking on other controllers. Look in Domain Controllers in Active Directory User and Computers on your PDC

2. Check for (and remove if necessary) the remote servers in Computers section of ADU&C on your PDC

3. Finally, delete the DNS entries on the PDC and replication will push the changes to any other secondary DNS servers in the domain.

4. Go home for tea and medals.

In addition I will recommend to take backup of server and seperate dns backup before you proceed with demotion:http://social.technet.microsoft.com/Forums/windowsserver/en-US/6409b8d5-da43-41f6-83ba-f706a6422dcc/dns-manual-backup?forum=winserverDS

If the server is removed from network you can safely delete the same.I will also recommend to run dcdiag /q and check if any error is reported.If the faulty server instances are also present in AD then you need perfrom metadata cleanup see this:http://www.petri.co.il/delete_failed_dcs_from_ad.htm
