Our company uses a DNS server provided by our ISP for Internet traffic. For internal resolution, we have to insert entries into each client HOSTS file and its becoming quite tedious. Also, when customers visit, they have trouble accessing our website because their resolving to our external IP address and the firewall is not going to allow them outside the firewall only to come back in.
Therefore, in Windows 2003, I want to set up an internal DNS server so that people can access our site and our users can access other internal network devices and servers. We do also have some people that access an iSeries server that is based off a single name. For example one is called INTERLG2. How would we do a DNS entry for that so that we don't have to mess with hosts files anytime somebody needs to access it?
