Let's say you want to query all the servers in AD, here is a PowerShell one liner to do it, you need to have Quest PowerShell commands for Active Directory installed of course.
Get-QADComputer -sizelimit 0 -OSName '*server*'|export-csv Servers.csv
You could limit the search to a particular OU by using the -searchroot switch.
Let's say every user (in IT) has two accounts - one is their regular user account and the other is their admin account. It could be in the form of xyz.admin(or any other format). How you go about searching your active directory and find all the .admin accounts?
it couldn't be easier than this:
Get-QADUser -ldapFilter '(SamAccountName=*.admin)'|export-csv admins.csv
Of course, you need to have PowerShell Commands for Active Directory from Quest installed first!
