Machine appears offline unless also connected via RDP
I have a 2 Channel TeamViewer License. Via RDP, I installed TeamViewer on a Windows 2012 R2 Server. I set it up for unattended access. I also configured it to allow Windows Logon and start TeamViewer with Windows. I then added it to My Computers on my desktop, which I plan to access the server from.
The problem is that the server appears offline unless I first connect to it with RDP, which defeats the whole purpose of having TeamViewer on it.
I've done this with other machines with no problems. Any suggestions as to what settings I should look at?
