Hi,

Recently migrated from SBS2003R2 to a full 2008r2 network.

I've run a DCDIAG /test:dns on our new 2008R2 Domain Controller and it fails with an error pointing to the old (removed) SBS2003 server.

HOw do I fix this?

MANY thanks!

Did you correctly demote the 2003 server before migrating?
Please do the Metadata Cleanup and delete entries from DNS server

Do the metadata cleanup the Expert has recommended below

http://technet.microsoft.com/en-us/library/cc816907(WS.10).aspx

Windows 2008 Server you can just delete the DC which will automatically do a metadata cleanup

Missing glue records would be pointing to DNS records.
Check your _msdcs.mydomain.local zone for old A records pointing to server-01

I've got a record in

DC->forward lookup zones -> domain.local -> _msdcs

Name server
server-01.MYDOMAIN.local

Would that be the issue then?

OK to delete it or should it be replaced with the name of the current Domain COntroller?

Ok to delete

On new Server run dcdiag /fix or restart netlogon service

Used http://www.petri.co.il/delete_failed_dcs_from_ad.htm

and old server is not listed in the site it was in.

I ran dcpromo successfully on the old server before it was removed.

shoud i delete the _msdcs folder or just the Name server record pointing to the old server?

Deleting the server from _msdcs fixed the issue.  Thanks to all
