Old PTR names Martin van der Kroef 4/25/2007 11:02:03 AM One year ago we concluded the migration from a Windows NT domain to a Windows 2003 domain. During the migration there was a two-way trust between the two domains and the servers appeared in the DNS in the Windows 2003 domain. These servers are later removed or replaced. New servers in the Windows 2003 domain now can have an IP address that belonged to one of the old servers. Now the A record for that server maps to the new name and the PTR record maps to the old (non-existent) server. Running ipconfig /registerdns on the new server is not possible. The System Event log shows an ID 11160 in dnsapi. How can I get rid of the old server names?

Delete them manually or perhaps script it with DNScmd if you can develop a "patter" for the script that makes this easier. (Like dumping them and filter first on some old range of addresses or names etc.) -- Herb Martin, MCSE, MVP http://www.LearnQuick.Com (phone on web site)

However when I try to delete the PTR record in the GUI, the record immediatle reappears in the zone. With dsncmd it is not possible to delete the record, "DNS name does not exist" I tried to create a new A record with the same name. Two PTR records are in the zone with the same name. Deleting the A record only deletes one of the PTR records. I also tried to rename the PTR record. A new PTR record is created with the new name, but the old record still exists. The ldp tools shows me that no object exists with the name in the PTR record. Any ideas? Martin

Would this PTR contain an uppercase letter? What is the SP level? You cannot delete DNS PTR records that contain uppercase characters in Windows Server 2003: http://support.microsoft.com/kb/842127/en-us -- Best regards, Kevin D.

This was supposed to be fixed in SP1 and SP2 was released a month or so ago. -- Best regards, Kevin D.
