This article describes the high-level steps to troubleshoot issues that you might have deploying a Group Policy to target machines or target users. For a rough understanding what
Group Policy is and what it tries to do, see http://technet.microsoft.com/en-us/library/cc725828(WS.10).aspx
Group Policy processing happens in two phases.
Group Policy Core Processing, where the client enumerates all Group Policies and settings that need to be applied. It reaches out to the Domain Controller to access
Active Directory and SYSVOL in order to gather required data for policy processing.
Group Policy CSE Processing, when the Client Side Extensions (CSEs), the little pieces of software in Windows make sure that settings configured by administrators
get enforced on the operating system to reflect them.
Before Group Policy can be troubleshooted, basic verification of functionality of Active Directory should be performed and that the client fulfills Active Directory requirements.
