I'm a systems administrator and my company has various sites across UK. Sometimes users have to travel between sites and often save their data on the C drive of the desktop. All sites are under on domain. I'm fairly new to this but is there is a way I can find out what computer a particular user logged on on a particular day. I mean is there any way we can query Active Direcory to find this out. ? I need to know the computer name the user logged on to .
