Group Policy Overview • Group Policy Definition • Preferences • Define Scope of Policy (Site, Domain, Etc.) • Inheritance/Enforce/Block • Administration/GPMC • Naming Conventions • Security Filtering/WMI Filters • RSOP /Modeling • Login Scripts/Startup Scripts • Fine-grained Password Policies • Security Templates (More detail later) • Machine vs. User Policies • Group Policy Loop-back • Change Control
User and computer configuration settings • Group Policy settings for users: • Desktop settings • Software settings • Windows settings • Security settings • Group Policy settings for computers: • Desktop behavior • Software settings • Windows settings • Security settings
Group Policy Container • Stored in Active Directory • Provides version information Group Policy Object Group Policy Template • Stored in shared SYSVOL folder • Provides Group Policy settings • Contains Group Policy settings • Stores content in two locations GPO Components
Computer starts Refresh Interval • Computer settings applied • Startup scripts run User logs on Refresh Interval • User settings applied • Logon scripts run When is a gpo applied?
Domain OU Domain GPO Site Site GPO OU OU Organizational Unit GPO Organizational Unit GPO What is a gpo link? Applied in order: Local Site Domain OU
Site policies • Second only to local polices • Conditional Polices depending on Network location (VPN, DMZ, etc) • Time Zones • Printer location related policies
Domain policies • Password and Account Policies • Security and Auditing Policies • Control Restricted Domain Groups • Do not use the Default Domain Policy
Default domain policies • Password Settings • Account Lockout Settings • Allow system to be shutdown without having to log on • Change Administrator account name to: • Change Guest account name to: • Clear pagefile on shutdown • Digitally sign server side communication • Digitally sign client communication
Fine grained password policies • New in AD DS 2008 • Allows companies to define different password policies for groups within their organization, without creating separate domains
User policies • Desktop lockdown discussion • Removal of My Documents folder from computer/Redirection • Removal of context menus • Remove Add/Remove programs • Password protect screen saver • Standard desktop? – same screen saver, desktop background, fonts, etc for certain users? • Allow/disallow shared folders • Login/Logout Scripts- SW installation • Loopback processing mode (Kiosks)
Machine policies • Roaming profiles – on or off, should they propagate to server • Startup scripts and shutdown scripts – async or sync • Run this at user logon – no matter which user • Disk quotas • Dynamic DNS • Group policy refresh interval • Security policy • EFS policy • (desktops) Remote assistance on/off • (desktops) system restore on/off/settings • (desktops) NTP – time settings
Guidelines for planning Gpos • Apply GPO settings at the highest level • Reduce the number of GPOs • Create specialized GPOs • Use the Enforced option only when required • Use Block Inheritance sparingly • Use security filtering only when necessary
