2008 R2 ADS Vocabulary - Session 3 Flashcards
Group Policy Processing
You can apply Group Policy settings at the local, site, domain, and OU levels.
All group policies that can apply to a user or computer do so,
blending their settings However, settings from different policies may directly conflict with each other.
Group Policy Processing
To prevent conflicts, policy settings in GPOs at different levels are processed in a specific order. That order is as follows (LSDOUC):
Local GPOs GPOs Linked to the Site Domain -Level GPOs GPOs Linked to OUs GPOs linked to Child OUs
You can choose to alter the default processing order using a variety of methods, including the following:
Block Inheritance
Enforced
Block Inheritance
The Block Inheritance option prevents an OU or domain from inheriting GPOs from any of its parent containers. However, GPOs that are marked as Enforced are always inherited.
Enforced
The Enforced option is a GPO link option that ensures the settings in the policy are applied regardless of blocked inheritance or the order of processing of linked GPOs.
GPO Status
The GPO Status option can be used to troubleshoot a set of applied policies if the desired end result of the policies is not what it should be by choosing to Disable the User portion, Computer portion, or all of a GPO. Separately, a GPO Link can also be disabled.
Link Order
The Link Order option controls the precedence order of multiple GPOs that are linked to the same particular container. The lower the link order, the higher its precedence. The GPO link with the link order of 1 has the highest precedence in that container.
GPO Filtering
Each GPO is set to apply to members of the Authenticated Users group, which contains all domain Users and Computers. If this group is replaced with a smaller group, then the Group Policy will be filtered to apply to only those members of the container who also are members of the security group referenced.
WMI Filtering
In the GPMC console a WMI script can be created to test for the absence or presence of system properties or values, such as Operating System, Service Pack, free disk space, RAM capacity, etc. This WMI script can then be bound to a GPO. If the receiving client does not meet the criteria of the WMI filter it will not receive ANY of the GPO settings.
Loopback Processing (Merge or Replace)
There is a Computer GPO Administrative Template Setting that will override the User logon’s normal GPO loading behavior. In “Replace” mode, when a user logs on to a Loopback Mode computer, the GPOs loaded will be the policies in the LDAP path of the Computer, not the User. This can enforce a kiosk-like consistent configuration of settings. In “Merge” mode, the Users settings are loaded, but the Computers path settings are also loaded, with the Computer’s path settings overriding the User’s.
Slow Link Detection
If the computer detects a slow connection (by default less than 500kbps, but the threshold can be changed or disabled) than certain portions of Group Policy, such as software deployment, will be skipped in Group Policy processing. Other portions of Group Policy, such as Security settings, cannot be skipped.
Credential Caching
Users’ credentials are automatically cached locally, based on previous logon attempts, to enable the user to log on if a DC fails and authentication on the domain is not possible. If a user logs on using locally cached credentials, Group Policy settings are not applied..
The configuration of Loopback Processing, Slow link detection, what will be loaded or skipped for a slow link, and Loopback Processing Mode are all configured in the following Administrative Template path:
“Computer
Configuration \Administrative Templates \System \Group Policy”
Creating a GPO
The GPMC provides a user-friendly interface that an administrator can use to create, view, and manage GPOs in an organization.
Starter Group Policy objects derive from a Group Policy object (GPO),
), allowing administrators to store a collection configured Administrative Template settings.
. A New GPO built from a Starter GPO will begin with all of the Administrative Template policy settings and values that were defined by the
Starter GPO
Starter GPOs can be exported to
other environments as needed.
By default, only members in the Domain Admins, Enterprise Admins, or Group Policy Creator Owners (GPCO) groups ca
create new GPOs and edit existing ones
A member of the Domain Admins group can choose to delegate the authority for creating and managing a GPO to
other users or groups in that GPO’s domain.
THE GROUP POLICY MANAGEMENT CONSOLE
Installing and Customizing the GPMC
The GPMC is a Microsoft Management Console (MMC) snap-in that you use in Windows Server 2008 R2 to configure group policy settings throughout various forests in an organization.
GPMC
GROUP POLICY MANAGEMENT CONSOLE
You can use the GPMC to perform several operations on GPOs, including the following:
- Searching for GPOs in a forest
- Backing up and restoring a GPO
- Importing settings from a backed up GPO to an existing GPO in the same forest
The GPMC enables you to plan the deployment of
a Group Policy using the Resultant Set of Policies (RSoP) data simulation, which is used to view the combined effect of a set of GPOs on systems and users.
