Installing OpenManage Essentials on a Domain Controller When installing OpenManage Essentials on a domain controller, it is recommend to install OpenManage Essentials with a remote database. For more information, visit http://support.microsoft.com/kb/2032911.

There are specific restrictions when running SQL Server on a domain controller, and given the resources demands of a domain controller, SQL Server performance may be degraded which will impact the performance of OpenManage Essentials. Therefore, it is recommended that you install OpenManage Essentials with an SQL Server instance available on a remote system. While setting up the OpenManage Essentials on a domain controller, ensure the following prerequisites are met:

• The network communication between the OpenManage Essentials system and the remote database system is functioning.

• The SQL Server user has permission to backup, create, and configure databases.

5

http://support.microsoft.com/kb/2032911


• When using SQL Server authentication, ensure that SQL Server & Windows authentication mode is enabled within SQL Server. See Enabling the SQL Server and Windows Authentication Mode in SQL Server.

• Ensure that TCP/IP is enabled in SQL Server using the "SQL Server Configuration Manager" tool. See Verifying the SQL Server TCP/IP status.

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 the installation on a domain controller, but 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.

• After SQL Server is installed on a system, you cannot change the system from a domain controller to a domain member. You must uninstall SQL Server before you change the host system to a domain member.

• 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.

Installing OpenManage Essentials on a Domain Controller With a Remote Database

Prerequisite:

Log on to the domain controller with administrator rights.

Steps

1. Download the OpenManage Essentials package from https://delltechcenter.com/ome, and extract the files to a local drive.

2. The self-extracting zip automatically launches the Autorun.exe window or you can manually launch the Autorun.exe.

5. To install OpenManage Essentials on a remote database, select “No”. On doing so, the installer will follow the Custom installation path where you can select a remote database for installing OpenManage Essentials.

6. To set up the OpenManage Essentials database on the remote system, click “Browse” on the “Database Server” screen, and select the remote system, or type the host name and database instance name in the “Database Server” field.

Perform the installation with one of the following authentication methods:

• Windows Authentication - If you are using a non-domain Windows account, the credentials must exist on both the domain controller and the remote system, and should also be identical.

Note: The windows user account must have the privileges required to create databases in SQL Server.

• SQL Server Authentication
