we use a software to distribute operating system (with ghost image).
it uses bootp to get IP then begin installation.
The problem is with the reverse dns records. When the installation continues it seems that the computer register itself to the dns with the image name. Then with the true name of the computer.
There is no problem with the forward dns records, but the reverses wasn't updated.
So there are mulitple computers with the same Reverse dns address. (Our dns servers are windows 2003)
the update ptr option is configured on the dhcp server.
