Previously I could Remote Desktop into this computer. Now I get an error saying that Remote Desktop might not be enabled or that the server might be too busy to accept connections.
Using netstat -a I see there is no listening on 3389.
In services, terminal services is started but when I try to stop and restart it, all of that is greyed out.
I haven't tried a restart of the computer yet since this is a critical server and I don't want to restart it during the week, I can do it on Saturday if nothing else works.
I'm assuming a computer reboot will fix this but I'm wondering how it got in this state in the first place and if there's any way to clear it without rebooting.
