Right click the row and select 'Delete'. If that doesn't work right click the node just above and select properties. In the tabs find the extra entries and then [Remove] one of the lines and click ok.

By doesn't work I mean that 'delete' isn't an option in the context menu when you right-click. It's just an a record. So when you view the properties of the ZONE you should be able to remove it  in the proper tab.

You should also set up stale record scavenging on your zone so that this is taken care of automatically in the future.

This article says Server 2003 but it should apply to Server 2008 as well.

I would check your DHCP settings as well to make sure this doesn't happen time after time..

Right click the DHCP server and go to the DNS tab.

Just to note, there is nothing inherently 'wrong' with more than one hostname resolving to the same IP.

For example, on my network, I have both:

SBSServerName

and

ProxyServer

resolving to the same IP address.

I do this so that, if I ever want to, I can move the proxying from the SBS box to another machine, and it won't require any changes to client machines - all I would do it change the IP in DNS.

Alan.

I guess you could try deleting the ptr record first and then the a record.  I remember having to do that at one point I believe.
