I'm looking for best practice ways of protecting access to password
storage in Active Directory. I have some immediate questions:

Where exactly are passwords kept?
Are these passwords kept in plain text?
How can I protect these passwords from being hacked? (Encryption,
restrictions, etc...)

Thank you in advanced

You will want to ensure that passwords are not stored using reversible encryption (by default they are not). This is generally only required if you are configuring a RADIUS server that will use CHAP for authentication. More information on reversible encryption settings for Windows password policies can be found here:

I would also review the Windows Server 2003 Security guide starting around page 33. That is where they begin discussing password policy. It is available here:
