Now you’ll want to click the “Remote settings” on the left side.


Next Check Box “Allow Remote Assistance Connections to this computer”
If this option is Grayed out, either you have a non Pro or Business version of Windows.
(or if this is a PC in a Domain, your Domain admin my disabled this, contact them.)


You can allow from any version, This is in case you have an older PC and you still want to connect.

III. Open PORTS on your Firewall.

This Example of Ports Forwarded to the PC from the Router (Your Internal IPs will differ)
You need to see “your” Firewall Instructions on how to forward to each PC


Bob Port: 3390
Mary Port: 3391
Frank Port : 3392
Helen Port: 3393

Save Port 3389 for your main Server…

IV.  Add Remote Listening Port to Each PC (On Each PC)

1)    Run REGEDIT on your PC.

2) Export the following key To Desktop: (Save as RDC.reg)
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp 

3) Edit the REG file and change the name of the Existing key to something like:

V. Next Firewall Ports need to be opened on Each PC

The Windows Firewall Snap-In will load…




Next Select on left “Inbound Rules”

Once it changes…

On the right now select “New Rule…”



Select “Port”

Make sure it’s TCP and Add the port corresponding to the PC you have.



Allow the Connection:


This doesn’t matter in Desktops in Domains that don’t move, but if it’s a laptop I’d say remove the Public


Then Name the Firewall Rule.. Click Finish

You will now see the new rule.
Do this on Each PC and You MUST REBOOT Each PC for it to work…

To Remote from outside use the External IP a Colon and then the Port, or use an Fully qualified External Domain that you created.
