I have a situation im facing with DNS issues. I have a small business server 2008 that is a domain controller, exchange, dns and dhcp. We are a computer repair business and have a secondary router and switch hooked up for our computer repair area. This is so the computers are somewhat segregated and helps us from bots sending emails and getting us blacklisted. The secondary router is a different subnet address. So the domain controller is a 192.168.22.1 and the secondary router is 192.168.23.1. In the secondary router we have the DNS pointing back to the domain controller,also has 192.168.22.1 static ip in the wan gateway. We are continuously having DNS issues with the computers behind the secondary 192.168.23.1 router. They will not resolve names properly and we cannot even download Dell drivers because of it. Will someone please give me some advice? I have tried entering the verizon dns and a secondary public DNS entry and then we have issues hitting internal file servers that are on the 192.168.23 network.
