DNS Host Name Tab

We use Ghost to update reps laptops. The ghost image name gets placed in the DNS host name tab in the TCP/IP stack. We use NewSID to apply the new SID and change the computer name to what we want it to be at the same time. The ghost image name beingin the DNS host name tab must be causing some athentication problems. Is there a way to change the computer name in the ID tab as well as the DNS tab at the same time ?
