We have an SBS 2011 network... and recently our windows 7 desktops stopped automatically locking after a set amount of time. I believe we were using a default Group Policy setting as this has always worked for us by default. Where do I find the settings to check on this and make sure it is still set to do this for us? If a user got up and walked away.... their desktop would automatically lock after so many minutes of idle time. Please advise?
