How to test the Autodiscover._tcp SRV record for Exchange

We needed to test a domain's autodiscover setup that we had them configure since we are not confident in the hoster's abilities anymore.

NSLookup brings us right to the door and we get the answer we require up front.

In this case the host had munged things with:

I tested our own domain and it works but is a bit more verbose than needed. It does show the different methods that the client will use to find the server though.

Thask for clarifying that. The way it's written the article makes it sound like what is in the picture is incorrect, which has been throwing me as I stare at it trying to find the error and compare it to the record my own host has created :)
