A Windows server has suddenly stopped accepting remote desktop connections.
When I try connecting with
MSTSC.EXE it reports
An Internal error has occured and with
RDCMAN.EXE it reports
[Unknown disconnection reason 4].
As, domain admin, I have connected into the server successfully using
psexec \\SERVER cmd and I can see that the 'Remote Desktop Services' service is running, and the server is listening on TCP port 3389:
C:\>sc query termservice SERVICE_NAME: termservice TYPE : 20 WIN32_SHARE_PROCESS STATE : 4 RUNNING (STOPPABLE, NOT_PAUSABLE, ACCEPTS_SHUTDOWN) WIN32_EXIT_CODE : 0 (0x0) SERVICE_EXIT_CODE : 0 (0x0) CHECKPOINT : 0x0 WAIT_HINT : 0x0 C:\>netstat -ano | findstr LISTEN | findstr :3389 TCP 0.0.0.0:3389 0.0.0.0:0 LISTENING 1640 TCP [::]:3389 [::]:0 LISTENING 1640
What can I try, other than rebooting the server?
