We operate a mainly Mac network but our 3 main video rendering machines are all Windows 7 PCs.
2 out of the 3 are accepting RDP connections but one of them just refuses to work both internally or externally.
All 3 have have Remote Desktop setup securely following this guide http://jack-brennan.com/securing-remote-desktop-on-windows-8-and-windows-7/
The RD ports are random and are definitely open and set up identically in terms of the port forwarding etc. After turning on firewall logging on the router for the problem PCs ACL, I can see the connection coming in and it being passing onto the correct static IP.
Currently the Windows firewall is completely disabled on the PC itself.
I have logon events enabled on the PC but don't seem to be seeing the attempts being logged.
As our users need to connect to these PCs from home (generally on Mac OS X) I am currently testing the the connection using MS Remote Desktop app on OS X. As I said the other 2 PCs work perfectly but I am now at a loss at to why this particular one will not work.
When I try to connect (externally) I get "Initializing" & "Negotiating Credentials" messages and then nothing, the app eventually times out and stops trying to connect.
Can anyone think of anything that I might be missing or can try to test what the issue might be on this one PC?
Any help would be hugely appreciated!
Thanks, Justin
