Windows DNS Audit

The following steps will allow you to audit windows servers to check that they have two DNS servers set in network settings.
It is very important that all servers have two DNS servers set. Even if customer users their own DNS they should always have two, that way if one fails DNS will still work.
Due to network and firewall restrictions these steps are best run from your local system using the VPN connection.
