The simplest explanation would be that when loopback processing is enabled, user policies are applied based on the location of the computer object and not the user object. This is useful in terminal server or computer lab environments because you may want to apply one set of policies regardless of who the user is. The following blog provides a pretty brief, yet accurate description. If you need more information, there is tons of it on MSDN, or you can always ask the list. There is always someone willing to help. http://daily-it.blogspot.com/2006/10/loopback-processing-of-group-policy .html Regards, Jamie Nelson | Operations Consultant | BI&T Infrastructure-Intel | Devon Energy Corporation | Work: 405.552.8054 | Mobile: 405.200.8088 | http://www.dvn.com <http://www.dvn.com/> From: gptalk-bounce@xxxxxxxxxxxxx [mailto:gptalk-bounce@xxxxxxxxxxxxx] On Behalf Of Steve Crompton Sent: Tuesday, January 06, 2009 7:49 AM To: gptalk@xxxxxxxxxxxxx Subject: [gptalk] (no subject) Hi Could you please explain Group Policy Loopback Processing ? im finding this very difficult to understand !
