AD DNS

[Daniel J Walsh]

Don't worry about the paronoia.  Lets just call the domain censored.com

Not sure how Microsoft works.  But your query was looking for
burner.censored.com
which does not exist.

Microsoft returned
burner.stores.censored.com

In order to have this happen on Unix.  You would need the search in 
resolv.conf to look like the following

search censored.com stores.censored.com
