ADM Files: Managing mixed environments ADM files provided in Windows are cumulative E. g. ADM Files: Managing mixed environments ADM files provided in Windows are cumulative E. g. , settings in Windows Server 2003. ADM files are a superset of settings in XP and 2000 ADMs OS applicability of setting indicated by “Supported on” field in UI Note: “Supported on” field is not yet supported on Win 2000 Up-level settings ignored on down-level clients E. g. Win 2000 ignores settings XP+ only settings General recommendation: Use ADM files from latest OS If possible, perform administration on XP or later Consider use of policy settings to control ADM behavior (see next slide)

ADM file management Group Policy Object Editor ADM files used to display UI in ADM file management Group Policy Object Editor ADM files used to display UI in “Administrative Templates” node ADM files loaded from Sysvol by default If local copy is newer, it’s uploaded to sysvol Note: issues with Win 2 k SP 3 & SP 4 (fix planned for SP 5) This behavior is configurable via 2 policy settings Never upload to sysvol (“Turn off Automatic Update of ADM Files”) Use local ADMs only - new for Windows Server 2003 GPMC ADM files used to generate HTML reports ADM files loaded from local computer by default If not found, loaded from sysvol User can specify custom location from which to load ADMs NEVER copied to sysvol

Security Policy Settings Account Policies Configure password, account, and Kerberos policies (domain only) Local Security Policy Settings Account Policies Configure password, account, and Kerberos policies (domain only) Local Policies Configure auditing, user rights, and security options Event Log Configure settings for application logs, system logs, and security logs Restricted Group Configure group memberships for security sensitive groups System Services Configure security and startup settings for services running on a computer Registry Configure security on registry keys File System Configure security on specific file paths Public Key Configure encrypted data recovery agents, domain roots, trusted certificate authorities, and so on IP Security Configure IP security on a network Wireless Software Restriction Configure wireless settings Configure which apps can be run or disallowed

Security Tips Account Policies must be configured at domain level Security settings always re-apply Security Tips Account Policies must be configured at domain level Security settings always re-apply every 16 hours Don’t apply full security templates through Group Policy – Those are intended for one time only File and Registry ACLs time consuming to apply and also tattoo Restricted groups don’t merge: See 810076

Internet Explorer Maintenance Set policy settings to control: Browser User Interface (Title, logo) Connection Internet Explorer Maintenance Set policy settings to control: Browser User Interface (Title, logo) Connection (Proxy, autodetect, etc) URLs: home page, favorites IE Security: Zones, Privacy, Content Ratings, Authenticode Programs Enhanced Security Configuration (ESC) on Win 2003 New secure configuration for IE impacts Zones and Privacy ESC-enabled and -disabled computers must be managed independently GPOs with ESC-enabled settings only apply to ESC enabled machines, and vice versa. ESC state of admin machine determines whether a GPO is ESCenabled or not

Folder Redirection Supports Server-Based Storage of Common Folders My Documents Application Data Desktop Start Folder Redirection Supports Server-Based Storage of Common Folders My Documents Application Data Desktop Start Menu Benefits Availability of user data on any computer Reduced network usage when users move between machines Increased ease of backup of redirected folders Used in conjunction with Offline Files to provide access when disconnected from network On XP and above, all redirected folders are automatically admin pinned for offline use For each folder, you can choose No policy - does not redirect Basic - redirects all users to the same place Advanced- redirects users to different locations based on security group membership

Folder Redirection Tips General recommendations: Consider redirection of My documents If using Roaming Profiles, Folder Redirection Tips General recommendations: Consider redirection of My documents If using Roaming Profiles, this is a must Optionally consider redirecting Desktop If users store documents on desktop Start Menu and App. Data generally not recommended for redirection Let the system create folders for each user to avoid improper ACLs To remove Folder Redirection, use the “Redirect to the local user profile” setting When using EFS, encrypt the local cache, not the folder on the server

Foreground vs Background refresh Foreground refresh At boot and logon Processing is synchronous: Logon Foreground vs Background refresh Foreground refresh At boot and logon Processing is synchronous: Logon prompt not displayed till computer processing complete Desktop not displayed till user processing complete Requires connectivity to domain All extensions processed Background refresh Approximately every 90 minutes (except for DCs, 5 mins) Interval and random offset configurable through policy setting Processing is asynchronous Software installation and folder redirection settings not processed

Processing Optimizations During refresh, GP is re-applied only if there are changes in the Processing Optimizations During refresh, GP is re-applied only if there are changes in the GPOs, or the list of GPOs Can override this to ALWAYS process via policy setting, for each extension Windows XP Fast Logon Optimization OS does not wait for network start before displaying logon screen Configurable via policy setting Computer policy is processed as background refresh at logon. Changes to Folder Redirection and Software Installation may require multiple reboots to apply

Question 4 Q: What are the new Group Policy features since Windows 2000 A: Question 4 Q: What are the new Group Policy features since Windows 2000 A: Introduced in Win. XP: Group Policy Results (RSo. P logging) WMI filter client support Software Restriction Policy – client support Fast logon optimization New policy settings New GPResult. exe based on RSOP Introduced in Windows Server 2003: GPMC: New admin tool for managing Group Policy Web download for both XP and 2003 Group Policy Modeling (RSo. P – planning) WMI Filters admin support Software Restriction Policies – Admin Support New Policy Settings

Question 5 Part 1 Q: What are requirements to use Group Policy Results A: Question 5 Part 1 Q: What are requirements to use Group Policy Results A: Clients must be running on XP or later Part 2 Q: Is there any dependency on whether I have a 2000 or 2003 based AD ? A: Group Policy Results is a function of the client. However the ability to delegate remote access to read Group Policy results data requires AD schema for Windows Server 2003 ADPrep /Forest. Prep

Question 6 Q: What are the requirements for using Group Policy Modeling A: Group Question 6 Q: What are the requirements for using Group Policy Modeling A: Group Policy Modeling is performed by a service that is only available on DCs running Windows 2003. There is no dependency on the client OS.

Question 7 Q: What are the requirements to use WMI filters? A: Client Dependencies: Question 7 Q: What are the requirements to use WMI filters? A: Client Dependencies: Clients must be running XP or later Win 2000 clients ignore the filter and always apply the WMI filtered GPO Server Dependencies: Forest: must have Windows 2003 AD schema (ADPrep /Forest. Prep) Domain: Must run ADPrep /Domain. Prep to use for clients in that domain DCs don’t actually need to be running Win 2003

Question 8 Q: Are there any dependencies in Group Policy on native mode vs Question 8 Q: Are there any dependencies in Group Policy on native mode vs mixed mode? A: No. However, various features do have dependencies on the following: Schema level of the forest (ADPrep /Forest. Prep) Domain configuration (has ADPrep /Domain. Prep been run? ) Presence of at least one DC

Question 9 Qa: Can I use GPMC to manage a my environment if all Question 9 Qa: Can I use GPMC to manage a my environment if all my DCs are running Windows 2000? Qb: Can I use GPMC if my clients are running Windows 2000? A: Yes. However, GPMC itself must run on a computer running Windows XP SP 1 or Windows Server 2003.
