I have encountered this issue twice now where the Windows 7 Professional PC is unable to be connected to via RDP. In both cases, the PC is acting as a file server and has SERVER as part of the Full Computer Name. These PCs, however, are NOT part of a domain - just a workgroup. As with other successful RDP setups I've completed, I have done the following:
1/ Set up a dns host name correctly with correct local 'host' internet IP (as confirmed via www.whatismyip.com
2/ Visited START>CONTROL PANEL>SYSTEM>REMOTE SETTINGS on the host PC and clicked on bullet point relating to 'allowing connections from computers running any version of remote desktop'.
3/ In the same window above, clicked on 'select users' and added 'Everyone' to the list.
4/ Accessed the firewall and creating a new inbound rule for a new port (3390)
5/ Changed the listening port via regedit (to 3390)
6/ Restarted PC
I am stumped! Accessing mstsc, entering <hostname>:3390 (even replacing the hostname with the internet IP) and clicking 'connect' only produces the following message after about 20 seconds:
"Remote Desktop can't connect to the remote computer for one of these reasons:
1) Remote access to the server is not enabled
2) The remote computer is turned off
3) The remote computer is not available on the network
Make sure the remote computer is turned on and connected to the network, and that remote access is enabled.
Incidentally, when setting up rdp, I can usually rdp into my work PC offsite from the PC I'm setting us and then rdp back from my work PC to the PC I'm setting up just to confirm that the connection is being made (which I know because I get bumped off). In both of these cases, I can rdp to my work PC just fine, but get the message above when trying the reverse.
Thanks in advance, experts - I look forward to hearing from you soon as this one's doing my head in.
