When I try to connect to Windows 2012 Server using Remote Desktop Connection, I'm connected for about 1 sec. and then disconnected with following error:

Because of a protocol error (code: 0x112f), the remote session will be disconnected.

Until yesterday, connection was working fine with no error, no server changes. I never saw this error before. I tried to lower visual appearance settings in Experience panel (found as possible solution to similar error), but with no result.

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.
