If you are using Bind as the DNS nameserver, **DONT** comment out the 
server services line, you will turn on the internal DNS server!

If 'LOCALHOST' is indeed the hostname of your AD DC, then you will need 
to change this, though as you are just testing it might be quicker and 
easier to re-provision

Also you seem to be using ntvfs instead of s3fs, do you really want to 
do this?
