AD Query

AD Query is a FREE utility that allows quick and easy auditing of any user or computer object within Active Directory.

Unlike the standard Users and Computers MMC, AD Query shows all data populated Schema, LDAP and Exchange mail-enabled attributes for the user or computer object.
With AD Query, there is no need to poke around in ADSIEDIT, LDAP or Exchange MMC, or use scripts to convert schema data to something humanly readable. AD Query does the binary string conversions for you. AD Query is 3 tools in one and a total time saver for the busy System Administrator.
