disclaimer: I am quickly finding out how little I know about DNS while fighting this one. I am setting up an ISA server, but am having a hard time with the DNS setup. My domain controler has DNS running, but will not allow forwarding because it is at the root. So I am wondering, can I put another DNS on the ISA server and allow forwarding on that one, or can I reinstall/reconfigure the DNS on my "PDC" to allow forwarding ?
