The reason for this is that A) the server is controlled by an administrator and B) there is a single line of communication between the DHCP and DNS servers. It is possible for a DHCP client to update the DNS (and Windows seems to prefer that way), but the DHCP server can set a bit that tells the client NOT to do that. (One reason to discourage clients changing their own names is that they might get it wrong and change someone else's name). > > Bob
