Unable to RDP onto computer but able to ping OK.

Hello amazing people!

I am currently trying to log onto two computers in the office via RDP but unable to do so.
I am able to ping the computers OK.

I have checked all RDC settings on the computer and all is enabled. I have tried restarted the services but still no joy.

I had run a virus scan but it may have not been a virus and just the scandisk USB application which was popping up. Doing a full scan on the system and 2 viruses popped up with scandisk USB on it.

I have tried renew IP address and flushing DNS but no joy.

I am able to manage the computer remotely OK.

Tried to readd the computer onto domain and still no joy with RDP.

Run SFC scan but still no joy.

I have checked everything i can on google and windows website but unable to find anything therefore hope you can help.

Computers has Windows 7 Pro on them.

Have you checked the Windows Firewall? Disable it and try again.

OK. Try to add this to your GPO:
Computer Configuration -> Policies -> Administrative Templates -> Windows Components -> Terminal Services -> Terminal Server -> Connections:

"Allow users to connect remotely using Terminal Services:"-> Enabled

If you are out of the office and they are in the office do they each have seperate IPs or have you configured a port forward? Would check theses are correct.


Also check that the Computers are 'remote desktop enabled' and also check that windows firewall rule is for the correct profile ie 'domain, private, public' that match your settings (probably domain) .

run a portscan to check the port is open.

Hope this helps :)

Nanders81 that has already been done. As for IP addresses and port forwarding the RDP ports are open, when i am out of the office i am able to RDP onto the other machines but these two. I have checked that remote desktop is enabled. Windows firewall is turned off at the GPO.

Check the IP-settings. Do these machines use the correct Gateway and subnet?

Do you connect to the computers thru IP or DNS? Try the IP-address in case of DNS.

I have tried via IP and computer name but no joy. The IP details is ok as the computers get DHCP. Tried applying static IP address but still no joy.

If you are able to RDP into other computers from an external location - and they are all behind a standard router, then you must be using port forwarding to accomplish this

The standard RDP port is 3389 - If a router forwards that port to a particular IP address internally then all calls to that external IP on port 3389 will go to that Computer and only that computer. (The exception is if you are going through SBS  and it's handling the traffic)

Regardless if your Firewalls are on or off or port are opened on any particular machine - The user must be a Mobile user, Administrator, or a member of the Remote Desktop security group in order to connect using RDP

You can alos change the RDP port in an individual machine and let the router handle the traffic. In normal cases where the Port is 3389 - you simply put in the external IP Address and whereever port 3389 is forwarded to is where the RDP will go. If you change the port to say 3390  then you need to change your host setting in the RDP Client to do for instance 10.45.34.22:3390  in order to get to another machine. If you do this you need to either change the Port on the PC or have a router capable of modifying an incoming port to another ip/port

For instance say you have PC-A  and PC-B
Both have 3389 as there default port
say PC-A is 192.168.0.111  and PC-B is 192.168.0.112

In the Router you can specify that all traffic on port 3389 be forwarded to 192.168.0.111  on port 3389

For PC-B - you need to tell the forwarding that al traffic on port 3390 goes to port 3389 on 192.168.0.112

To get to PC-A your use <your External IP>
To Get to PC-B you use <your External IP>:3390

I presume your user account is a member of the Remote Desktop Users group on those computers?

cantoris - Already mentioned that (paragraph 3)

Can you connect to these computers from within the office using other tools - eg pointing the event viewer snap-in at them?

Can you telnet to their port 3389 from within the network and get some form of response?
