![]() ![]() ![]() ![]() Deploying Group Policy Using Windows Vista. With the introduction of Windows. The number of Group Policy settings has increased from approximately 1,8. Windows Server 2. Service Pack 1 to approximately 2,5. Windows Vista and Windows Server 2. This gives you more than 7. This document will help you sort through the new and updated features available in Windows Vista, and it provides a number of best practices to help you deploy Group Policy. Group Policy allows you to work more efficiently because it enables centralized desktop management. Centrally managing desktops can decrease the total cost of ownership (TCO). Loss of end user productivity is one of the major costs when measuring TCO in a distributed computer environment. The following items contribute to loss of end user productivity. User error: For example, modifying system files, which renders computers inoperable. Combining these policy settings creates desktops specific to a user's job responsibility and level of experience. Group Policy applies not only to users and client computers, but also to member servers, domain controllers, and any other Microsoft Windows computers within the scope of management. By default, Group Policy that is applied to a domain (that is, applied at the domain level, just above the root of Active Directory Users and Computers) affects all computers and users in the domain. Active Directory Users and Computers also provide a built- in Domain Controllers organizational unit. If you keep your domain controller accounts there, you can use the Group Policy object (GPO) Default Domain Controllers Policy to manage domain controllers separately from other computers. Expanding on the foundation established in Windows Server 2. Windows XP, Group Policy is improved with greater coverage of policy settings and extensions, better network awareness and reliability, and easier administration. Defining Group Policy. Client Side Extensions Windows 7Group policy will not allow me to turn on my firewall. I can't turn on my firewall because Group Policy won't allow. Here we will take you from start to finish on how to easily configure the Windows Firewall via Group Policy. Firewall Settings. ![]() You use Group Policy to define specific configurations for groups of users and computers, by creating Group Policy settings. These settings are specified through the Group Policy Management Console (GPMC) or the Local Group Policy Editor and contained in a GPO, which is in turn linked to Active Directory containers, such as sites, domains, or OUs. In this way, Group Policy settings are applied to the users and computers in those Active Directory containers. You can configure the users’ work environment once and rely on the system to enforce the policies as defined. This approach results in Group Policy applying policy settings to users and computers in those Active Directory containers. You can configure the user's work environment once and rely on Windows Vista to enforce policy settings you defined. Group Policy capabilities. You create specific policy settings that determine how Windows behaves and to keep users and computers secure. The following sections describe the key features of Group Policy. Registry- based policy settings. Implementing registry- based policy settings is the most common form of policy setting in Windows. You can define registry- based policy settings for applications and Windows using the GPMC and the Local Group Policy Editor. For example, you can enable a policy setting that adds the Run command to the Start menu for all affected users, in Windows Vista. Security settings. Group Policy provides options for you to set security options for computers and users within the scope of a GPO. You can specify security settings for the local computer, domain, and network. For added protection, you can apply software restriction policies that prevent users from running files based on the path, URL zone, hash, or publisher criteria. You can make exceptions to this default security level by creating rules for specific software. Group policy version = Windows Firewall. If for some reason you can't apply group policies you can use the following commands to configure the windows firewall. I'd like to completely disable any group policy. He also warns of one risk to using Windows Firewall with Group Policy. Managing Windows Firewall through Group Policy. Windows Settings. Software restrictions policy settings. To defend against viruses, unwanted applications, and attacks on computers running Windows XP and Windows Server 2. Group Policy includes new software restriction policy settings. You can now use policy settings to identify software running in a domain and control its ability to execute. Software distribution. You can manage application installation, updates, and removal centrally with Group Policy. Because organizations can deploy and manage customized desktop configurations, they spend less money supporting users on an individual basis. Software can be either assigned to users or computers (mandatory software distribution) or published to users (allowing users to optionally install software through Add or Remove Programs in the Control Panel). Users get the flexibility they need to do their jobs without spending time configuring their system on their own. You can use Group Policy to deploy approved packages. For example, in a highly managed desktop environment where users do not have permission to install applications, the Windows Installer service will perform an installation on the user's behalf. In addition, for highly managed workstations, Windows Installer integrates with the software restriction policy settings implemented through Group Policy to restrict new installations to a list of acceptable software. Computer and user scripts. You can use scripts to automate tasks at computer startup and shutdown and user logon and logoff. Any language supported by Windows Script Host, including the VBScript, Java. Script, PERL, and MS- DOS. ![]() Folder Redirection provides centralized management of these folders and gives you the capability to easily back up and restore these folders on behalf of users. Internet Explorer maintenance. You can manage and customize the configuration of Microsoft Internet Explorer on computers that support Group Policy. The GPMC and the Local Group Policy Editor include the Internet Explorer Maintenance node, which you use to edit Internet Explorer security zones, privacy settings, and other parameters on a computer running Windows 2. What’s New in Windows Vista Group Policy. Disable Group Policy VistaIn Windows Vista, enhancements to Group Policy significantly improve the ability to plan, stage, deploy, manage, troubleshoot, and report on Group Policy implementations. This section describes some of the key new features in Group Policy. Deploying power management settings. All power management settings have been Group Policy enabled, providing a potentially significant cost savings. Controlling power settings through Group Policy saves organizations a significant amount of money. You can modify specific power settings through individual Group Policy settings or build a custom power plan that is deployable by using Group Policy. Restricting device access. You can centrally restrict devices from being installed on computers in their organization. You will now be able to create policy settings to control access to devices such as USB drives, CD- RW drives, DVD- RW drives, and other removable media. Improvements to security settings. The Windows Firewall and IPsec Group Policy settings are combined into the Windows Firewall with Advanced Security Extension to allow you to leverage the advantages of both technologies, while eliminating the need to create and maintain duplicate functionality. Some scenarios supported by these combined Windows Firewall and IPsec policy settings are secure server- to- server communications over the Internet, limiting access to domain resources based on trust relationships or health of a computer, and protecting data communication to a specific server to meet regulatory requirements for data privacy and security. Expanded Internet Explorer settings management. You can open and edit Internet Explorer Group Policy settings without the risk of inadvertently altering the state of the policy setting based on the configuration of the administrative workstation. This change replaces earlier behavior in which some Internet Explorer policy settings would change based on the policy settings enabled on the administrative workstation used to view the settings. Assigning printers based on location. The ability to assign printers based on location in the organization or a geographic location is a new feature in Windows Vista. When mobile users move to a different location, Group Policy can update their printers for the new location. Mobile users returning to their primary locations see their usual default printers. Delegating printer driver installation to users. You can now delegate to users the ability to install printer drivers by using Group Policy. This feature helps to maintain security by limiting distribution of administrative credentials. Summary of new or expanded Group Policy settings. To review a table that summarizes new or expanded categories of Group Policy settings, see http: //go. Link. Id=5. 40. 20. Scope of Group Policy tools. The Local Group Policy Editor and Group Policy Management Editor. The Local Group Policy Editor and the Group Policy Management Editor are used for configuring and modifying Group Policy settings within a single GPO. The Local Group Policy Editor is used to edit Local Group Policy Objects (LGPOs). The Group Policy Management Editor, which is available from within the GPMC, can be used to edit domain- based policy objects. For information about the GPMC, see the next section. Each Windows Vista operating system has one or more LGPOs. The policy settings are applied to the LGPO manually with the Local Group Policy Editor. LGPOs contain fewer policy settings than domain- based GPOs, particularly under security settings. Also, the Local Group Policy Editor does not provide support for managing Group Policy Preferences. LGPOS do not support Folder Redirection, Windows Deployment Services, or Group Policy Software Installation. Administrators also need to be able to quickly modify Group Policy settings for multiple users and computers throughout a network environment. The GPMC and the Local Group Policy Editor provide you with a hierarchical tree structure for configuring Group Policy settings in a GPO. Windows Firewall GPO's. User Rating: / 2. I'm comfortable on the couch writing this article. Like anyone else nowadays, I want to be able to work anywhere I want. Secure ofcourse. A step in that direction are active directory group policies for Windows Firewall with Advanced Security. This post describes: The network types: Home, Work, Public and Domain. The firewall profiles: Private, Public and Domain. Defining default firewall group policy settings. Creating inbound and outbound rules. Do's & Don'ts. Determine the location. The first important task is to determine the kind of location of the network. I trust my company network more than I trust the one at the local burger company, so it makes sense to tighten the firewall rules there. The Windows (Vista, 7 and 2. NLA - Network Location Awareness - determines the type of network consulting the user. After connecting to a new network, Windows asks the user to define the network. Choices are Work network, Home network and Public network. If Windows can't distinguish the network at all, it chooses Public network automatically. This happens e. g. This option is called Domain network and can not be choosen or changed by hand. Different network types in Windows firewall. Windows Firewall with Advanced Security distinguishes three types of networks instead of four. Public and Domain are available, but Home and Work network are combined to Private. Group policy settings. Now that the types of network are clear, let's take a look at the GPO. The Windows Firewall with Advanced Security settings are found under policies - > Windows Settings - > Security Settings. You can see the inbound and outbound rules here, but first define what happens when no rules are set. To do this open the properties of Windows Firewall with Advanced Security. The tabs show you polices for the three types of networks, each containing the same settings. So, the default behavior is set at network type level. Recommended in the GPO for each type of network is to turn the firewall on, block inbound traffic and allow outbound traffic. Outbound traffic is traffic that you (or your computer) initiate yourself while inbound is initiated by others, so the recommended settings make sense. Set these and your halfway there. I'm slightly more paranoid myself, so in the Public Profile tab, I set the Outbound connections to Block. To make sure I can do anything at a public place I have to create some outbound rules. Inbound Rules. Although it's safe to block all inbound traffic, I want to allow administrators to manage the computers. For the administrators' VLAN 1. I create a rule to allow all inbound access: 1. Right click Inbound Rules en click New rule. A wizard appears to help you create a new rule. I want to allow full access to a certain IP range, but I don't see any predefine option for that, so I choose Custom. The next question is what program to use fro the rule. I choose All programs. I want all traffic allowed so I select Protocol type Any. Next is the part to define the IP- range. I add the network 1. Remote IP addresses. I choose Allow the connection. The administrator's are on the domain netwerk only, so I deselect Private en Public. Give the rule a catchy name and description and finish the wizard. It will be visible in your inbound rules list. Outbound Rules. The same way I created the inbound rule, I create outbound rules for the public profile to allow the computer DNS access and allow the Internet Explorer program to use HTTP and HTTPS traffic. Do's and Don'ts. Last, some things to consider. Don't : Never block all outbound access for the domain and Private profile. At startup the private profile will be used. Only when there is domain connection, will the profile be changed to domain. If the private profile's connection to the domain is blocked, no domain access will be possible, including GPupdate to collect new settings. Do : Start with the recommended settings supplemented with inbound rules for administrator access. Do : Test your settings! Do : Think about acquiring updates (Windows Update, Virus definitions, etc). Do : Think about the freedom you allow the users. Think about internet access, chatting, printing, streaming media, VPN, etc. Especially when they are at home. Don't : Don't get discouraged by these Do's and Don'ts. This post applies to: Windows 2. Windows 2. 00. 8 R2, Windows Vista, Windows 7.
