Save costs and operate more efficiently with managed domain services
Azure AD Domain Services enables you to use managed domain services—such as Windows Domain Join, group policy, LDAP, and Kerberos authentication—without having to deploy, manage, or patch domain controllers.
Increase operational efficiency
Enable managed domain services for virtual machines and directory-aware applications deployed in Azure with a click of a button. Reduce operational and maintenance costs associated with managing identity infrastructure for your virtual machines and legacy applications.
Run legacy applications in the cloud
Easily migrate on-premises apps to a managed domain. Streamline management of all applications from your legacy, directory-aware apps alongside your modern cloud apps with a single identity solution.
Rely on a managed, highly available service
Azure AD Domain Services includes multiple domain controllers to provide high availability for your managed domain. Ensure business continuity with guaranteed service uptime and resilience to failures.

Frequently asked questions about Azure AD Domain Services
Can I create multiple managed domains for a single Azure AD directory?
No. You can create a single managed domain serviced by Azure AD Domain Services for a single Azure AD directory.
Can I enable Azure AD Domain Services in an Azure Resource Manager virtual network?
Yes. Azure AD Domain Services can be enabled in an Azure Resource Manager virtual network. Classic Azure virtual networks are no longer available when you create a managed domain.
Can guest users invited to my directory use Azure AD Domain Services?
No. Guest users invited to your Azure AD directory using the Azure AD B2B invite process are synchronized to your Azure AD Domain Services managed domain. However, as passwords for these users aren’t stored in your Azure AD directory, Azure AD Domain Services has no way to synchronize NTLM and Kerberos hashes for these users to your managed domain, so they can’t sign in or join computers to the managed domain.
Does Azure AD Domain Services include high availability options?
Yes. Each Azure AD Domain Services managed domain includes two domain controllers. You don’t manage or connect to these domain controllers—they’re part of the managed service. If you deploy Azure AD Domain Services into a region that supports availability zones, the domain controllers are distributed across zones. In regions that don’t support availability zones, the domain controllers are distributed across availability sets. Learn more about availability options for virtual machines in Azure.
How long does it take for changes I make to my Azure AD directory to be visible in my managed domain?
Changes made in your Azure AD directory using either the Azure AD UI or PowerShell are automatically synchronized to your managed domain. This synchronization process runs in the background. There’s no defined time period for this synchronization to complete all the object changes.
Can I pause an Azure AD Domain Services managed domain?
No. Once you’ve enabled an Azure AD Domain Services managed domain, the service is available within your selected virtual network until you delete the managed domain. There’s no way to pause the service. Billing continues on an hourly basis until you delete the managed domain.
