WS2008R2SP1 Domain Controller Security Compliance Template Issue

I am working on a new Domain Controller Security Policy and just tested in my engineering domain SCM template “Domain Controller Security Compliance 1.1”  Few second after I import and link that GPO to Domain Controllers OU I loose RDP connection to all DCs.  I checked all the security Firewall settings, RDP settings and authentication settings and cannot figure out what setting is causing it. As soon I disable the link I can remote via RDP to my DCs.  I noticed in the event log that event below after linking the GPO.  Any idea or clue what setting that is?
