Question : Unable to Delete Reverse DNS Record

I'm trying to clean up our network DNS and have two reverse DNS entries that will not delete.  We are running AD and Exchange on SBS2003 which is also our DNS server and set up w/DHCP.  Under DHCP, DNS is set to enable and Dynmically update.  I don't see the two records in DHCP or forward DNS.  Also, we've added some thin clients to our network and I see them in DHCP (no name, just IP) but not in DNS, is this normal?

This is not my area of expertise so any help would be appreciated.

You probably haven't set the DHCP server up with security to update the DNS server.

In the DHCP MMC, right click the DHCP server, select properties.  Go to the advanced tab, and press the credentials button, and supply a correct username (Domain admin, unless you know otherwise)
