I have a mixed environment in which we have a central office where users would be local to the DC server, for these users the Local office agent would be best.  However, the majority of the staff works as consultants at other company's office buildings.  Since we have no control over their environment we have determined that using the remote office agent would work best.

2 questions come into play that I need help with:

1) Would the best option to use the GPO method to determine the agent and would the "Remote Office" agent be the best to install by default?

2) Can the "Remote Agent" do DNS name resolution or do we need to put in our Public IP address into the configuration?

I hope this makes sense if not I can provide more details.
