Remote desktop connection protocol error 0x112f

This error may be triggered by insufficient memory on RDP server.

After few tries with this error, RDP managed to get a connection to the server and I was able to stop a bogus service consuming too much memory. This can be done also with sysinternals or sc.

Server restart helped, I'm able to connect to server again.

Might not be a solution for all but I found that if I reduced the screen resolution of the RDP session, I was able to get in. The server was at 95% capacity I went from 3 high res monitors to 1 800x600 window.
