Old Computer Names & IPs
Posted on 2011-04-19
I have inherited a rather large domain & the past network admin did not keep DNS or Active Directory clean by leaving the domain properly. In other words, when a new computer came in to be installed, he just unplugged it & put the new on in place with a different IP & NetBIOS name.
Now, that I've came along, I have noticed this. I have 6 domain controllers all are global catalog servers. I need to go through & manually delete numerous records.....instead of me manually pinging each IP or NetBIOS name to make sure it is alive or dead, is there any tool I can run that will check the domain for any computers that have not logged into the domain, lets say in a few weeks, so I can compare my list to that report & just delete the computers?
