Without telling us, what type of other DNS server you use, nobody can help you. I don't know, if your other DNS server is able to test the availability of an ip-address via ping before handing out the address to the client, but that would probably be the way to go. Wolfgang

hi this is about AD +Legacy DNS (stand alone dns) running in server 2003 regards ankith
