Easy experience out-of-the-box Embody best practices that map to Microsoft security guide 8 System Starter GPOs: User and Computer case Available for Vista and XP SP2 Enterprise Client (EC) and Specialized Security Limited Functionality (SSLF) System vs Custom Static / Editable ADMX / Security Settings
  9. 9. New UI: More intuitive, integrated help content, no more tabs Support for: REG_MultiSZ REG_QWORD
  10. 10. Preference Settings Not true “Policy” More control of desktop – more settings! Not limited to policy-aware applications Ease of administration through rich UI Better targeting New in Windows 7 Support for new Power Plan settings Support for new Schedule task triggers, actions, etc.
  11. 11.
  12. 12. Group Policies Group Policy Preferences (Native / Managed) • Users can change • Setting are enforced, settings user cannot change • Multiple items per settings GPO • Settings revert back to • Can write registry original setting settings to more than • Highest precedence HKCU, HKLM hives • Work only on specific • Granular Targeting of registry location individual items
  13. 13. Drive Mappings Regional Settings Printer Mappings Shortcuts Start Menu Internet Explorer Settings
  14. 14. Local Users and Groups Services Network Shares Environment Variables
  15. 15. Familiar Experience Clearer to understand and find Easy to manage Better control of individual settings – Red/Green Powerful browsers Avoids typing errors Configure settings quicker
  16. 16. 29 different targeting options Boolean AND, OR, IS, IS NOT Wildcard support “WSBNE*” Target on the item, not just the GPO
  17. 17. Robust targeting 29 types Item level targeting, Boolean logic (And, Or, Not) not GPO level Collections Intuitive UI No need to learn query languages
  18. 18. Apply once and do not reapply Remove when no longer applicable Create – Replace - Update - Delete More than just Enable vs Disable
  19. 19. Active Directory: Windows 2000 Console - Group Policy Manager Console - Snap-in Part of the Remote Server Admin Tool (link and end) One Windows 7 client or Windows Server 2008 R2 Terminal Server Client - Client Side Extensions (CSE’s)
  20. 20. Client Side Extensions Windows Update/WSUS SMS / SCCM Download and Install Logon Script (ironically) SOE Image Client Side Extensions not installed? Nothing happen

  24. 24. The GP team recommends this strongly FRS Issues File Based Replication Does not self heal Does not tell you when its broken DFS-R for SYSVOL requires: Windows 2008 Domain Functional All Windows Server 2008 DC’s minimum replication.aspx
  25. 25. Have heard up to 11,000 GPOs Not best practice GPMC has perf issues loading Management difficulties Troubleshooting difficulties Migration difficulties Recommendation: Consolidate AGPM is tested up to 2000 GPOs
  26. 26. What about any server dependencies? Are there any schema changes required? What about the Vista Central Store? Will ADMX create an impact on my policies?
  27. 27. Does policy itself replicate any differently? Is it actually stored any differently? Do you still use the same tools to diagnose replication issues like Ultrasound (FRS)? With the move from Winlogon to a service does this mean users can deny policy applying? Any impact for co-existence between Windows Server 2003 GP and Windows Server 2008 and onwards?
  28. 28. Will I have to recreate all the policies again for Windows 7? Can I drop ADM files into the Central Store? Do we have plans to provide an updated GPMC/GPOE to support Windows XP administrative PC’s with ADMX and the Central Store? Is it a good idea to separate Vista GPO from the Windows XP GPO's through new OUs or filtering with WMI? Is there any way to restrict editing GPOs from certain OS versions ? i.e.: restrict editing from anything below W2K3 ?
  29. 29. Guidance Firewall Policy Will apply the most permissive rule Best Practice: Separate Policy for Windows Vista/7 machines IPSEC Policy Old UI for pre-Vista New UI for Vista Best Practice: Separate Policy for Windows Vista machines Three methods for policy separation Grouping (Read/Apply control) Separate OU with GPO link WMI Filter Select * FROM <WMI_CLASS> WHERE <WMI Property>=<value> Select * FROM Win32_OperatingSystem WHERE Caption="Microsoft Windows XP Professional" AND CSDVersion="Service Pack 2"
  30. 30. Guidance Auditing Policy Totally different in XP to Vista and Windows 7/2008 R2 Fine Grained (Vista/W7) as opposed to clumsy and awful (XP) Separate it
