Port Forwarding for RDP

December 29Hits:1
Advertisement

I'm trying to setup Remote Desktop on my computer. It's currently running Windows 7. RDP is set to allow for incoming connections.

I've followed the instructions at PortForward.com, but am having no luck. Here's the details:

Router: TP-LINK WR841N -- WanIP=192.168.0.2, LanIP=192.168.0.1                           DHCP Bounds = 192.168.1.100 (start) through 192.168.1.199  Computer Static IP (Assigned) = 192.168.1.151  External IP (whatsmyip.com) = 111.67.xxx.xxx 

Also of note, I have port 3389 forwarded on the router to IP 192.168.1.151 and it is enabled for all protocols.

Now when I run PFPortCheck, I get "Could not test port 3389 because some other application has that port locked. Please close any applications that may be using this port and try again."

Now this is funny, as I have removed all antivirus and firewall software from my computer, and disabled Windows Defender.

So, I run "netstat -aon" and I get the following:

TCP    0.0.0.0:3389    0.0.0.0.:0    LISTENING    PID=1216 

PID 1216 doesn't show in Task Manager, but using "tasklist" from the command line reveals that it's svchost.exe. So I killed the process with "taskkill /PID 1216 /F" and it magically terminated.

Returning back to PFPortCheck, I try to test the port again. Only now I get "We were unable to ping your router" and "Your port is NOT OPEN or not reachable!".

So, can anyone tell me how I can open this port so I can walk accross the street and RDP into it?

Thanks,

Jason

I'm pretty sure the process that's locking 3389 is RDP itself. If you disable remote connections first and test again it should be able to test successfully, at least that's how it worked for me.

  1. Control Panel > System > Remote Connections
  2. Disable remote connections and Apply.
  3. Test again with port checker, could take a minute for RDP to release the port
  4. After you have your results you can re-enable remote connections and Apply

This should at least narrow it down for you, currently I have the ports test successfully after disabling RDP. Not sure what the rest of the problem is.
