A more surgical AD Query tool that is totally free is called (surprisingly) AD Query from
www.sysoptools.com
It differs from the above tools in that it displays all configured schema data for a single user or computer object. It smartly leaves out <null> fields so you don't have to poke through a list of non-configured fields. It converts binary / tick strings to date/time formats. very handy. Your can run multiple instances side by side and compare results between objects, i used it once to troubleshoot a kerberos ticket / trust issue between two identical servers. total time saver.
