Ok I will explain this the best I can. Our network, that was set up long before me. Our Ip range is 172.16.x.x and now we also have 172.17.x.x. Our DC has our dhcp server on it and works fine for the 172.16.x.x address. The 17 address range cannot see any assets on the network that carry 172.16 range and cannot access the internet. Both ranges are setup in the router. Our 172.16 range for uses a 255.255.255.0 mask. Our server is 2003. Can anyone tell me how to get the two ranges to see each other?
