Reporting on AD computers

Monitoring the AD is a necessary albeit time-consuming task. With larger numbers of users and computers to manage, you need all the help you can get, and PowerShell makes it easy to keep track of things.

A computer that has not logged on for an extended period could represent a security risk or could be a lost/stolen computer. It could also be a system that you have not rebooted after having applied patches and updates.

This recipe creates a report of computers that have not logged on or that you have not rebooted for a while.
