I have setup remote access to a XP machine via RDP and it has been working fine for the last 12 months. Recently the user started to complain that her remote access is not working, and after rebooting, she has access to her PC remotely again, but only once. If you reboot the PC and dont log in, you can access the PC remotely, but only once, if you log out you can't log in again (you get a message saying that a remote session could not be established). If you reboot the PC and log in locally, you can't access the PC remotely again (same message as above) untill the PC is rebooted. The RDP listener seems to be working (netstat -a shows the port open and listening). It seems to me that some rouge service is stopping RDP from working, I have checked the services that are running but see nothing unusual. I have questioned the user as to new software installed which may have caused this problem, but am assured nothing has been installed. Any Ideas ? Any help would be greatly appreciated.
