I think. I'm changing from ISDN to a cable modem. The cable co. says I must have my ISA server set for DHCP. Followed the instructions in the Learning Zone for this type of setup. I tested it against my ISDN router. Set it to do DHCP, gave the DHCP Client rule the IP of the ISDN router as the remote computer. It won't get an IP from it. I stopped the ISA Control, as suggested, still won't get the IP. Maybe it is the router, but I thought I would check ahead if anyone has any thoughts on what else I might be missing.
