I have 2 networks joined by a T1 with a 1720 on each end of it. I use a W2K server for dhcp and have 2 zones created for each network. One is 10.10.10.x/255.255.255.0 and the other is 10.10.20.x/255.255.255.0. I can't get the .20 network to use dhcp. I have dhcp enabled on the clients and i have fumbled around with some iphelper addresses with no avail. My dns/dhcp server is 10.10.10.252. Any help would be great....
