I am using Windows Remote Desktop to connect and remotely manage one of my Windows server. I understand that there are many other better remote control software such as VNC but I try to minimize the installation of third party software on the Windows Server 2008. If you don’t know what is Remote Desktop, it is a protocol developed by Microsoft, which allows you to view the display and control the mouse and keyboard of another computer at different location, as if you were sitting in front of the computer.
remote desktop auto locked when idle
I never had any problems with Remote Desktop, except for only one annoyance which is if I leave it idle for a few minutes, it auto logs off and I had to re-enter the password to login again. This is very annoying whenever I am reading the log files or the console messages that is displayed on screen. Fortunately I’ve found the setting on how to disable remote desktop auto logoff on idle.

I actually spent a few days to find the solution because I misunderstood the problem at the first place. I thought I was being auto logged out when idle but it turns out that it was the screen that was locked. No wonder setting “Never” for idle session limit in RDP Properties didn’t work.

By default Windows Server 2008 activates the screen saver if computer has been idle for 10 minutes and the setting “On resume, display logon screen” will also be checked. So if Windows detects no activity for 10 minutes, the screen saver will be activated and when we get back to the Remote Desktop Connection, the screen saver is removed and then prompts to login. To solve this problem, you can either disable the screen saver or remove the logon screen on resume.

To disable the logon screen when idle, here’s what you need to do:
1. Right click Desktop and select Personalized
2. Click Screen Saver
3. Uncheck “On Resume, display logon screen” and click OK.

Now you can remain idle on the remote desktop connection as long as you want and you won’t be locked out.
