Windows Server 2008 R2. How do you reconcile or run a program on the server to show which users have not logged into the network or had a response from a DHCP server in the past year? Not sure if I'm explaining that right. One time I had someone do this for me on our server and it showed the users that have not logged into the network for a year. They ended up having a red x beside the name. Want to clean up active directory.
