Problem: Over the years my Active Directory computes OU was starting to get cluttered with old computer accounts. Surprising how many go in and out over the years. I could not find a way through AD users and computers to mass delete these objects.
Solution: Came across a program called OldCmp and it non only did exactly what I needed but it will also provide reports, disable and delete old computers. Many other options and safeguards in this little executable to keep you from deleting active workstations. A must have tool for managing your Active Directory
