I am trying to retrieve a group policy from a Windows Server 2008 Active Directory and change the minimum password age, maximum password age, and minimum password length in a C# application. Is there a way to do this? So far I have only found out how to create new Group Policy objects using Interop.GPMGMTLib (gpmgmt.dll), yet I haven't figured out how to change the policy's password rules and I am not sure if there is an easier way.
