8. Right-click on a blank spot in this folder and choose Paste to copy the ADMX files

and the en-us ADML folder to the central store. Because an en-us folder already

exists, a prompt opens stating that if any files exist in the folder with the same name

as the files being placed in that folder they will be merged. Check the Do This for All

Current Items check box, and click the Yes button.

9. Close the window and open the Group Policy Management Console.

10. Create a new policy named Office2007TestGPO and open it for editing.

The main reason to use the central store when extending group policies with new admin-

istrative templates is so that any administrator who attempts to create, view, or edit a

domain policy will be able to view all of the available settings.

Deploying Software Packages Using Domain Group Policy Objects

Domain Group Policy Objects can be used to deploy Windows Installer compatible MSI

software application packages. Many software vendors provide their desktop and some-

times even their server applications as MSI packages, which can make deploying these

applications using domain policies very easy. Some applications, however, are not so

nicely packaged and require the use of a third-party MSI packaging product or must be

deployed using a different method. Software deployment with domain policies is func-

tional but does not provide very flexible configuration and deployment options, such as

those included in Windows Server Update Services for Windows and System Center

Configuration Manager 2007 R2, formerly Systems Management Server, for all types of

applications and several other third-party software vendors that provide software deploy-

ment software suites. Deploying a software package using Group Policy requires the

following steps:

1. Define the parameters of the installation and locate, create, and customize the

Windows Installer MSI package.

2. Place the MSI package on a network share that allows the necessary Active Directory

computer and/or user accounts to read the package and any other necessary files

during installation. This includes configuring the share and NTFS permissions as

required and, in many cases, selecting the Authenticated Users group works well

unless tighter security of the software application is required.

3. Add the software package to a new Group Policy Object to apply to users or comput-

ers and define the deployment options. Deployment options can be defined when

the package is added to a policy, but after the software package is deployed to a

system, any changes to the configuration of the software package will not be picked

up by that system unless the package is then configured to reapply the package,

which can cause some undesirable results.

4. Link the GPO to a test organizational unit that contains only one or a few computer

and/or user accounts to test the policy.

5. If the software package is being deployed to computers, including Windows XP,

Windows Vista, or Windows 7 systems, configure Group Policy settings to force

these systems to perform Synchronous Foreground Refresh, which forces the system

to wait for the network to start before attempting to process Group Policy Objects.

Windows servers wait for the network before processing group policies by default.

6. Verify GPO application and software installation results and, if necessary, update

the GPO settings as required to achieve the desired installation configuration and

behavior.

7. After the software package has been verified or updated to run correctly, remove the

ptg

link from the test OU, and link the GPO to the desired domain, site, or organization-

al unit(s).

Creating a New Software Installation GPO

Deploying software applications using a Group Policy Object is a simple task after the

package is created and any necessary customizations to the installation behavior are

defined. In many cases, the desired deployment option is to deploy the application to

computer objects. When applications are deployed to computers, the applications are

installed during the startup cycle of the system. This, of course, requires that the system

starts while connected to the organization’s network over a fast link and waits for the

network to start before attempting to process group policies with the software package.

To deploy a packaged MSI software application using a domain group policy to a

computer, perform the following steps:

1. Log on to a designated Windows Server 2008 R2 administrative server.

2. Locate the MSI package that will be deployed using the new Group Policy Object and

copy it to a network share. Ensure that the Authenticated Users group has at least

Read Share permissions and Read and Execute NTFS permissions in the shared folder.

3. Open the Group Policy Management Console from the Administrative Tools menu.

4. Expand the domain to expose the Group Policy Objects container and select it.

5. Right-click the Group Policy Objects container and select New.

6. Type in a name for the new GPO such as CorporateSoftwareGPO and click OK to

create the new GPO. Do not select a starter GPO as this GPO will only contain the

software package and does not need to have any prepopulated information.

7. After the GPO is created, right-click on the new GPO and select Edit.

8. When the Group Policy Management Editor opens, expand Computer

Configuration, expand Policies, and double-click on Software Settings.

9. Right-click on the Software Installation node and select New, Package.

10. A Browse window opens. Locate the MSI package and click OK to add the package to

the GPO. The package must be available on a network share and should be refer-

enced using a UNC path.

11. When the Deploy Software window opens, select the Assigned option button, and

click OK to complete the process.

12. After the process completes, which can take a few minutes, the package will be listed

in the right pane. Right-click the new package and select Properties to open the

advanced property pages.

13. In the property pages for the package, review the settings on the Deployment tab to

determine if the package should be automatically uninstalled if the computer is

removed from the application of this policy, as shown in Figure 27.31.

14. With the property pages still open, review the settings on the remaining tabs and

make any required changes to the way the application package will function.

15. After the package is configured, click OK to close the property pages, and close the

Group Policy Management Editor.

16. Return to the Group Policy Management Console, and link the GPO to an organiza-

tional unit that has a few test or pilot systems on which the package can be installed.

17. Locate and log on to a system in the linked OU and reboot it to attempt to apply the

new GPO and install the software package.

18. Troubleshoot and repair the GPO and package as necessary to achieve the desired

functionality.

19. After the GPO is working as desired, link it to the intended site, domain, or OU.

20. Back up the GPO and log off of the test system and the administrative workstation.

Synchronous Foreground Refresh

Group Policy processing occurs at computer startup, shutdown, and periodically during

the background refresh interval for computers. Processing for users occurs at user logon

and logoff and periodically during the background refresh interval. Certain functions of

Group Policy, including software installation, user folder redirection, computer startup

and shutdown scripts, and user logon and logoff scripts, require the network to be avail-

able during processing. Windows XP, Windows Vista, and Windows 7 systems do not wait

for the network during computer startup and user logon by default and by design. This

feature provides faster computer reboots and faster user logon processes but can also cause

some Group Policy processing issues. When software installations, folder redirection,

computer startup, and/or user logon scripts are defined within domain group policies, it

might be required to also enable the Always Wait for the Network at Computer Startup

ptg

and Logon setting within group policies. The setting is stored in the Computer

Configuration node and must be applied as follows:

. GPOs that define computer startup scripts or computer-assigned software installa-

tions should have this setting enabled within the policy. Software installations that

are assigned should be set to this configuration but published software installation

GPOs can be left with the default processing configuration.

. If GPOs exist that define user logon scripts, assigned software installations, or folder

redirection settings that require processing before Windows Explorer is opened, the

computers that the users will log on to must have a GPO that applies this setting.

Configuring this setting within the policy that contains the user settings will not have

the desired effect unless the user’s computer is also in the container that is linked to

the GPO or unless a different policy that applies to the user enables this setting.

To configure Synchronous Foreground Processing of group policies, perform the following

steps:

1. Log on to a designated Windows Server 2008 R2 administrative server.

2. Open the Group Policy Management Console from the Administrative Tools menu.

3. Expand the domain to expose the Group Policy Objects container and select it.

4. Right-click the Group Policy Objects container and select New or select an existing

policy to update.

5. If a new GPO is being created, type in a name for the new GPO, and click OK to

create the new GPO.

6. After the GPO is created or if an existing GPO will be updated, right-click on the

desired GPO and select Edit.
