Microsoft Exchange Server 2013 Setup has detected that the computer you’re attempting to install Exchange 2013 on is an Active Directory domain controller. Installing Exchange 2013 on a domain controller isn’t recommended.
If you install Exchange 2013 on a domain controller, be aware of the following issues:
- Configuring Exchange 2013 for Active Directory split
permissions isn’t supported.
- The Exchange Trusted Subsystem universal security group (USG)
is added to the Domain Admins group when Exchange is installed on a
domain controller. When this occurs, all Exchange servers in the
domain are granted domain administrator rights in that domain.
- Exchange Server and Active Directory are both
resource-intensive applications. There are performance implications
to be considered when both are running on the same computer.
- You must make sure that the domain controller Exchange 2013 is
installed on is a global catalog server.
- Exchange services may not start correctly when the domain
controller is also a global catalog server.
- System shutdown will take considerably longer if Exchange
services aren’t stopped before shutting down or restarting the
- Demoting a domain controller to a member server isn’t
- Running Exchange 2013 on a clustered node that is also an
Active Directory domain controller isn’t supported.
We recommend that you install Exchange 2013 on a member server.
