I have one distant office to maintain, out of the country, few hundred kilometers away. As there were no problems, I did not connect to that server via RDP for few months. Today they called for some change to make, a 5-minute simple administrative task.
But I cannot connect remotely anymore!
With "DOMAIN\Administrator" account, my login is simply rejected each time, saying username or password is not correct. But it is! I am the only admin and this is the only admin password.
Just in case, I always setup a spare domain admin user with full rights. But I was not able to connect with this user either! I get this error:
The remote session was disconnected because there are no remote desktop license servers available
I have access to remote computers via TeamViewer, I have access to Router.
Any idea how to solve the problem?
Server is 2012 Foundation, domain controller, 10 users, nothing special, just file and database server.
