Software restriction policies, new in and Windows Server 2003, were created to address the problem of regulating unknown or untrusted code. Software restriction policies are security settings in a GPO provided to identify software and control its ability to run on a local computer, site, domain, or OU. Most organizations employ a set of known and trusted programs. However, if users install and run other programs, these programs might conflict with or change configuration data in the known and trusted programs. Or, the newly installed user programs could contain a virus or Trojan horse. Software restriction policies protect your computer environment from unknown code by enabling you to identify and specify the applications allowed to run. These policies can apply to computers or users, depending on whether you choose to modify settings in User Configuration or Computer Configuration. When software restriction policies are set, end users must adhere to the guidelines set up by administrators when executing programs.
With software restriction policies, you can Control the ability of programs to run on your system. For example, you can apply a policy that does not allow certain file types to am in the e-mail attachment directory of your e-mail program if you are concerned about users receiving viruses through e-mail.
Permit users to run only specific files on multiuser computers. For example, if you have multiple users on your computers, you can set up software restriction policies and access control settings in such a way that users do not have access to any
software but those specific files that are necessary for their work.
Decide who can add trusted publishers to your computer.
Control whether software restriction policies affect all users or just certain users on a computer.
Prevent any files from running on your local computer, OU, site, or domain. For example, if you have a known virus, you can use software restriction policies to stop the computer from opening the file that contains the virus.
Software restriction policies should not be used as a replacement for antivirus software. Software restriction policies do not work on Microsoft Windows NT 4 or Windows 2000 systems.
You are preparing a package for deployment. Which of the following actions
should you perform if you receive the message Cannot Prepare Package For
Deployment?
a.Check your permissions for the GPO
b.Check connectivity with the SDP
c.Check your permissions for the SDP
d.Set the appropriate category for the package
e.Set the auto-install property for the package
The correct answer is b. If you are preparing a package for deployment and you receive the message Cannot Prepare Package For Deployment, one of the actions you should take is to check connectivity with the SDP
The tasks for deploying software with Group Policy are:
1.Plan and prepare the software deployment
2.Set up an SDP
3.Create a GPO and a GPO console for software deployment
4.Specify the software deployment properties for the GPO
5.Add Windows Installer packages to the GPO and select package deployment method
Set Windows Installer package properties
To set Windows Installer package properties, complete the following steps:
1.Open the GPO console for the software deployment. In the Computer Configuration or User Configuration node, open Software Settings.
2.Click the Software Installation node.
3.In the details pane, right-click the package for which you want to set properties, and then click Properties.
In the General tab of the Properties dialog box for the package, shown in ,you can type a new name for the package in the Name box, if desired. You can also type a URL that provides user support in the URL box.
Click the Deployment tab. In the Deployment tab of the Properties dialog box for the package, shown in Figure 12-7, select one of the following in the Deployment Type area:
a Published, to allow users in the selected site, domain, or OU to install the application using either Add Or Remove Programs in Control Panel or application installation by file activation. If this is an application under the Computer Configuration node of the Group Policy Object Editor console, the Published option is unavailable, because packages can only be assigned to computers, not published.
Q Assigned, to allow users in the selected site, domain, or OU to receive this application the next time they log on (for assignment to users) or when the computer restarts (for assignment to computers).
In the Deployment Options area, select one of the following:
a Auto-Install This Application By File Extension Activation, to use the application precedence for the filename extension as determined in the File Extensions tab of the Software Installation Properties dialog box. If this is an application under the Computer Configuration node of the Group Policy Object Editor console, the check box appears dimmed and selected, because by default the application is installed automatically.
The following are the best practices for implementing folder redirection:
Allow the system to create the folders If you create the folders yourself, they may not have the correct permissions set.
Use fully qualified UNC paths, for example: \\servername\sharename Although paths like C:\Foldername can be used, it is not advisable because the path might not exist on the target computer.
Plan Group Policy settings sparingly—justify the selection of each setting as you would the creation of a domain or OU. Choose settings based on their ability to help you to simplify the administration of computers and users.
Build GPOs by using a decentralized or a centralized design. A decentralized design uses a base GPO applied to the domain, which contains policy settings for as many users and computers in the domain as possible. Then this design uses additional GPOs tailored to the common requirements of each OU and applied to the appropriate OUs. A centralized design uses a single GPO containing all policy settings for the associated site, domain, or OU.
Administrative control of GPOs can be delegated by using a centralized, decentralized, or task-based administrative control design. In the centralized design, administration of Group Policy is delegated only to top-level OU administrators. In the decentralized design, administration of Group Policy is delegated to top-level and to second-level OU administrators. In the task-based design, administration of specific group policies is delegated to administrators that handle the associated specific tasks.
You are one of several network administrators for Contoso Pharmaceuticals. One of your network users tells you that they’ve attempted to log on several times, but they keep getting the same error message telling them that the domain controller is down. You know that the domain controller is fine, so you go to the user’s desktop to see the error message.
Before you can see the error message, you need to create the problem. Perform the following steps to create the problem:
1.Log on to Server2 using the domain administrator user name and password.Demote Server2 to Member Server using Dcpromo and the DemoteContoso.txt
answer file. The answer file is located on the Supplemental CD-ROM in the \70-294\Labs\Chapter09 folder.
2.Log on to Serverl using the domain administrator user name and password.
3.Open Active Directory Users And Computers. Click on the Computers container.You should see SERVER2 in the right windowpane.
Select and right-click the SERVER2 icon and click Reset Account. When prompted about resetting the computer account, click Yes, and then click OK.
Go to Server2. Try to log on to the domain using the contoso.com domain administrator user name and password. You should see the following error message:
“Windows cannot connect to the domain, either because the domain controller is down or otherwise unavailable, or because your computer account was not
found. Please try again later. If this message continues to appear, contact your system administrator for assistance.”

When you install Active Directory on your network, it becomes the main database for finding resources in your organization. The resources in your network are represented by Active Directory objects. You should be familiar with the common Active Directory objects listed in Table 9-1.
The information that allows a user to log on to Microsoft Windows Server 2003, such as user logon name.
The information about a person who has a connection to the organization.
A collection of user accounts, computers, or other groups that you can create and use to simplify administration.
A pointer to a shared folder on a computer. A pointer contains the address of certain data, rather than the data itself. When you publish a shared folder or printer in Active Directory, you are creating an object that contains a pointer to the shared folder or printer.
A pointer to a printer on a computer. Windows Server 2003 automatically adds printers that you create on domain computers to Active Directory. A printer on a computer that is not in Active Directory must be manually published.
The information about a computer that is a member of the domain.
The information about a domain controller including an optional description, its Domain Name System (DNS) name, its preMicrosoft Windows 2000 name, the version of the operating system loaded on the domain controller, the location, and who is responsible for managing the domain controller.
Contains other objects, including other OUs. Used to organize Active Directory objects.
Objects are either container objects or leaf objects. A container object stores other objects and occupies a specific level in a subtree hierarchy. A leaf object does not store other objects and occupies the endpoint of a subtree. When you attempt to locate objects in Active Directory, you enter criteria for the system to use in the search. These criteria must be previously included in the properties for the object when the object is created. This is why it is a best practice to complete all attributes that are important to your organization when you create Active Directory objects. The more attributes you include, the greater the flexibility when you search for objects.
A security or distribution group often used to assign permissions to related resources in multiple domains. You can use a universal group to assign permissions to gain access to resources that are located in any domain in the forest. In domains with the domain functional level set to Windows 2000 mixed, universal groups are not available. In domains with the domain functional level set to Windows 2000 native or Windows Server 2003, universal groups can contain user accounts, computer accounts, global groups, and other universal groups from any domain in the forest.
The Ifmember utility is commonly used in batch files and logon scripts to determine group membership before running a command. You can see how the Ifmember utility works by performing the following steps:
1. Insert the Supplemental CD-ROM and run the \70-294\Labs\Chapter08\Lab8.bat batch file if you have not already. This batch file creates several groups and makes Amy a member of those groups. When the batch file runs, it will leave the commands it runs on-screen for you to review. Press the spacebar when you are finished reviewing what happened.
Run the IfMember_Setup.exe program from the \70-294\Labs\Chapter08 folder on the Supplemental CD-ROM. The Microsoft Web Installation Wizard appears.
3- Click Next to proceed.
4.Read the license agreement. If you do not agree, you cannot continue. If you agree, click the I Agree option button. Then, click Next to proceed. The Destination Directory opens.
5.Adjust the installation location if necessary, and click Install Now.
6.Click Finish.
7.In the new command prompt window, type and press Enter.
Type notepad c:\membership.txt and press Enter. You’ll see a list of your current group memberships displayed in Notepad.
Group scopes allow you to use groups in different ways to assign permissions. The three group scopes are global, domain local, and universal. Global security groups are most often used to organize users who share similar network access requirements. Domain local security groups are most often used to assign permissions to resources. Universal security groups are most often used to assign permissions to related resources in multiple domains.
Use the following strategy for planning groups: place user accounts into global groups, create a domain local groups for a group of resources to be shared in common, place the global groups into the domain local group, and then assign permissions to the domain local group.
The following scope changes are allowed in domains with the domain functional level set to Windows 2000 native or Windows Server 2003: global to universal, as long as the group is not a member of another group having global scope; domain local to universal, as long as the group being converted does not have another group with a domain local scope as its member; universal to global, as long as the group being converted does not have another universal group as its member; and universal to domain local.
You should avoid running your computer while logged on as an administrator because running Windows Server 2003 as an administrator makes the system vulnerable to Trojan horse attacks and other security risks. If you frequently need to log on as an administrator, use the Run As program, which allows you to run specific tools and programs with permissions other than those provided by the account with which you are currently logged on.
