Windows domain account permissions

Limitation 1: Using non-administrative accounts for multiserver administration

Enlisting target servers to a principal server may fail with the post-obit fault bulletin: "The enlist operation failed."

To resolve this mistake, restart both the SQL Server and the SQL Server Agent services. For more information, see Outset, End, Break, Resume, Restart the Database Engine, SQL Server Agent, or SQL Server Browser Service.

Limitation 2: Using the Local Arrangement account for multiserver administration

Multiserver administration is supported when the SQL Server Agent service is run nether the Local System account only when both the master server and the target server reside on the same computer. If yous use this configuration, the post-obit bulletin is returned when you enlist target servers to the primary server:

"Ensure the agent start-up account for <target_server_computer_name> has rights to log on as targetServer."

You can ignore this informational bulletin. The enlistment functioning should consummate successfully. For more than information, run into Create a Multiserver Environment.

Limitation iii: Using the Network Service account when it'due south a SQL Server user

SQL Server Agent may neglect to start if you run the SQL Server Agent service under the Network Service account, and the Network Service account has been explicitly granted admission to log into a SQL Server instance as a SQL Server user.

To resolve this, reboot the computer where SQL Server is running. This simply needs to be done in one case.

SQL Server Agent may fail to start if you run the SQL Server Agent service under the Network Service account and Reporting Services is also running on the aforementioned reckoner.

To resolve this, reboot the figurer where SQL Server is running, and then restart both the SQL Server and the SQL Server Amanuensis services. This only needs to exist washed once.
