Default Domain Group Policy – What Should Be Configured?

Ever since I started working with Microsoft Active Directory (AD) in July 2001, I have always wondered what should be configured in the Default Domain Group Policy Object (GPO).  I have had a couple of my AD mentors tell me what should be in the Default Domain GPO and I have parroted their recommendation for years now because I agree with them.  I am sure I also read somewhere in the past 12 years the Best Practices for this GPO but just have never been able to find it.  This morning I finally came across an article from Microsoft that clearly states what the Best Practices are for the Default Domain GPO.
