DCDIAG TESTS X PROTOCOL (Firewall Purposes)

Hi all,

For those who are looking for knowing what protocol each test on dcdiag command uses, below you can check the full list.

It's useful when you need to make sure the firewall rules are allowing communication between DCs, when you run the command dcdiag /e for example, to test all DCs in the enterprise, or dcdiag /a to test all DCs in the same Site of the DC that you are executing the command.

It is a simple tip, but I hope it can help you.

Cheers!
