DNS Server Installation
The DNS service (Domain Name Service) is the Achilles heel of an Active Directory structure. Since network communication is performed by only using names for reasons of understandability (e.g. www.tomshardware.com), there must be a quasi-permanent conversion between the names and the IP addresses that are behind them - and vice versa. A forward lookup searches for an IP address based on a name, while the reverse lookup searches for a computer name based on an address.
The installation of the DNS service is over in a jiffy (screenshot above), only it usually doesn't work as desired right from the start.

It is very important to install a Reverse Lookup Zone. It is only with this that the DNS server also able to establish names based on IP addresses.
