For anyone who has worked with Active Directory, they know that AD is dependent on it’s associated DNS zones/records. If for some reason these stop resolving, all hell breaks loose in the environment.

To monitor these necessary zones are resolving in DNS, I turned to PowerShell and wrote a simple script to test resolving the tcp, msdcs, udp, sites, domaindnszones and forestdnszones zones that I run from a client machine.
