RDP is enabled but doesn't show up in netstat

0

I've enabled RDP on a laptop, but I can't connect to it. Pinging the laptop works. nmap shows ports open, but not RDP. netstat on the laptop shows nothing listening on 3389. I've also tried rebooting.

Additional info:

Start > Computer > Properties > Remote Settings > Remote:

Remote Settings

Relevant registry settings:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\fDenyTSConnections = 0
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\Wds\rdpwd\Tds\tcp\PortNumber = 3389

Nmap scan:

$ nmap xxx.xx.xx.xxx

you've rebooted I assume? – Frank Thomas – 2013-06-05T20:51:10.073

Yep, I've tried rebooting. – Nick ODell – 2013-06-05T21:04:01.307

Have you checked to see if Windows firewall is blocking it? – Derrick – 2013-06-05T22:06:10.340

1Check to see if the service is running. Start---Run---Services.msc – Scandalist – 2013-06-05T22:09:00.827

@Scandalist That worked. Turns out 'Remote Desktop Services' was disabled. If you make that an answer, I'll accept it. Thanks! – Nick ODell – 2013-06-05T22:22:14.527

RDP relies heavily on the Windows Firewall Service whether it is enabled or not. Allowing the RDP service via manual registry settings is not always possible. First enable your Windows firewall prior to turning Remote Desktop Connections off and on again. Apply the change, then try and connect. Always connect using the IP address of your remote computer unless you are in a corporate or private LAN environment with fully working DNS. If it works you can then disable Windows firewall if it was disabled before. I have noticed that if the firewall service is disabled when you try to use the GUI to enable RDP, it will not allow it to be enabled even if you manually configure the registry and start the relevant services. Good luck!

This might help you too.
