Password complexity is enabled.
Password Age:  60-days
History:  Last 4 passwords cannot be used.
Length:  At least 8 characters.

An audit requirement is to force the users to change at least 3 characters of their previous password.
In other words, the user cannot use: Password1, Password2, Password3, etc.  They would need to change at least 3 of the characters - example:  "P@33w0rd2"

No you would need a 3rd party add-on of sort to accomplish that.

Right, Microsoft has failed to incorporate this. MS has only advised people to write and use their own password filter DLLs. http://blogs.technet.com/b/tristank/archive/2005/07/19/passfilt.aspx and http://msdn.microsoft.com/en-us/library/windows/desktop/ms721766(v=vs.85).aspx fit in here as they provide insight on that DLL.

However I recommend using a 3rd party product: Anixis ' password policy enforcer - it can do nearly everything you can imagine http://anixis.com/products/ppe/

Be assured that Anixis' product is super easy and as far as I can see, even flawless. Never have I used a software that was so intuitive and created no trouble at all. Also make sure to get a good dictionary word list for it to use (ours is 300 MB ;-) )
