  • Restrict DNS Registration

    I have a weird situation. I need to find a way to have only certain IP subnets register their address with my DNS servers.

    The reason I need to restrict is because I have some users that come in remotely and they get a private IP before they get authenticated via vpn. In these cases, the private IP is getting registered in my DNS. I am finding many instances where a single IP has dozens of names attached to it, and DNS shows they were registered on or near the same time.

    I would like to be able to use GPO to force all IP's that are in subnet1 to register, but everything else not register. I can do this with vbscript easily, but I would rather use GPO.

    So I need to eliminate all of these multiple machine names per IP and eliminate all registration for records in private IP subnets.

    Any ideas?
