Implement Group Policy in Microsoft Entra Domain Services

Manage Group Policy Objects in Azure AD DS

What Group Policy Objects Do

Group Policy Objects (GPOs) are a way for administrators to manage settings and configurations across computers in a network. In traditional on-premises Active Directory, GPOs control things like password requirements, software installation, and security rules. Azure Active Directory Domain Services (Azure AD DS) brings this same capability to the cloud, allowing organizations to apply consistent policies across hybrid environments where some servers run on-premises and others run in Azure.

The Sysvol Share Path

When you need to work with GPOs, you must understand where they are stored. The sysvol share path follows a specific format: \\\sysvol\\Policies. This path lives on the domain controller and contains all the policy files that define rules for your network. Administrators use this path to search for specific terms within policy files, such as registry.pol, which stores registry-based settings. When organizational needs change, administrators can modify or delete rules directly in these policy files to update how computers behave across the domain.

Creating and Managing Policy Settings

Configuring GPOs involves three main tasks. First, you create rules within policies that define what settings should be enforced, such as requiring complex passwords or blocking certain applications. Second, you delete unnecessary rules that no longer serve the organization, keeping policies clean and focused only on needed configurations. Third, you update policies when security requirements change or when the organization adopts new procedures. Each of these actions helps ensure that the policies applied to computers match the current needs of the business while maintaining security standards.

How GPOs Affect Network Configuration

Group policies can control how computers handle network connections. In some cases, connections might fall back to direct internet access or become blocked depending on how policies are configured. GPOs can also set geolocation settings that determine how traffic is routed and detected by services. When services need accurate location information, administrators may need to ensure that the original source IP address is preserved rather than being translated, so that traffic routing works correctly and services can identify the user's actual location.

Virtualization Considerations

When running virtual machines in environments like Hyper-V, there are specific GPO considerations. The Global Secure Access client must be installed on virtual machines to enable certain policies, but it should not be installed on the host device itself. This means traffic is handled separately for the host machine versus the guest virtual machine. For Hyper-V configurations, administrators need to account for this separation when applying policies, ensuring that each virtual machine receives the appropriate settings while the host remains unaffected.

Proxy Settings Through Group Policy

Organizations can control proxy behavior through GPOs by configuring a proxy auto configuration (PAC) file. This file tells computers which traffic should go through the proxy and which traffic should bypass it. Administrators can exclude specific Fully Qualified Domain Names (FQDNs) and IP addresses from proxy tunneling, ensuring that certain requests reach their destination directly. For example, if an organization uses forwarding profiles, HTTP requests for specific FQDNs or IPs can be configured to bypass the proxy entirely, improving performance and ensuring proper connectivity for critical services.
