if you know these computers are actually up and running, then most likely they have a firewall that is blocking remote access.
Is this possible?
Here is the link to a document that discusses required ports...
If this isnt related to what is going on, then send an email to firstname.lastname@example.org and we can work directly with you.
We have the windows firewall turned off via Group Policy. File and Print sharing is also enabled by Group Policy. So would I need to now create a GP that will allow all those ports listed in that PDF?

Are you using some other endpoint security solution, like McAfee, Symantec, or Trend Micro, that would be blocking these ports?
if you dont have a firewall on the computers you are trying to manage, then is it possible that you have these ports blocked at the routers?
The problem, according to the information you have provided, is that NONE of the ports are open.
Port 135 is the endpoint mapper and that appears to be closed.
Port 139/445 (File and Print Sharing) also appears to be closed.
The computer is also not pingable.
