Installing OpenManage Essentials on a Domain Controller
When installing OpenManage Essentials on a domain controller, it is recommend that you install
OpenManage Essentials with a remote database. There are specific restrictions when running SQL Server
on a domain controller, and considering the resources demands of a domain controller, SQL Server
performance may be degraded which will affect the performance of OpenManage Essentials. For more
information on the restrictions when running SQL Server on a domain controller, see the Microsoft
Knowledge Base article ID 2032911 at support.microsoft.com.
NOTE: For security reasons, it is recommended that you do not install SQL Server 2012 on a domain
controller. SQL Server Setup will not prevent you from installing SQL Server on a domain controller,
however, the following limitations apply:
• You cannot run SQL Server services on a domain controller under a local service account.
• After SQL Server is installed on a system, you cannot change the system from a domain member
to a domain controller. You must uninstall SQL Server before you change the host system to a
domain controller
• SQL Server failover cluster instances are not supported where cluster nodes are domain
controllers.
• SQL Server Setup cannot create security groups or provision SQL Server service accounts on a
read-only domain controller. In this scenario, Setup will fail.
When setting up OpenManage Essentials on a domain controller, ensure that the following prerequisites
are met:
• Ensure that network communication between the system on which OpenManage Essentials is
installed and the remote database system is functional.
• Ensure that the SQL Server user has permission to backup, create, and configure databases.
