I was using my work PC normally and it suddenly went to the lock screen. I did not touch the keyboard and I was using the mouse, merely reading my e-mail in Google Chrome.
Is it possible for the system administrator to view a user's PC screen on the network and even control the PC without the user's authorization, knowledge or confirmation (via a dialogue or something)? Is this possible with standard Microsoft out-of-the-box network admin software?
Is there anything I should look for in my Task Manager that might indicate this is the case?
