I can connect via a local connection LAN, but can't connected over the internet. I've opened and forwarded port 3389 to the server's address. RDP is enabled and working on the server. It's headless, so that's how I admin it.
I saw this video about enabling the Remote Desktop Services role. I tried what was suggested, but still no luck.
I am able to access other services, like remote admin on my router, without a problem.
Any ideas?
