By the group policy, all PC's which are joined to the domain are forced to be locked after 15 minutes of inactivity.Is there any way to disable this auto lock on client-side? The situation is like the following. I am using a virtual machine and this is also joined to the domain (using "Bridged connection"). When I am using my PC, I often running the virtual machine too, but I do not constantly use it. When I am trying to use the virtual machine, it is often locked. I think disabling the lock in a VM does not cause any security hole, because the real host PC will be locked when I am not using it. I was thinking about creating a utility that send a bogus mouse movement message to the system, but is there any cleaner way to do this? Or is there already a utility like it?
