SQL Server blocked access to the process ' dbo.sp_set_sqlagent_properties ' of component ' Agent XPs ' because this component was shut down as part of this server's security configuration.

SQL Server 2008 reported the following error when configuring the Distribution Wizard:

Use the agent XPs option to enable SQL Server Agent extended stored procedures on this server. If you disable this option, SQL Server Management Studio Object Explorer will not display the SQL Server Agent node.

These extended stored procedures are automatically enabled when you start the SQL Server Agent service by using the Surface Area Configuration tool.

Attention:
SQL Server Management Studio Object Explorer does not display SQL Server Agent nodes unless these extended stored procedures are enabled in any state of the SQL Server Agent service.

The following example enables SQL Server agent extended stored procedures.

The possible values are:
0, which indicates that the SQL Server agent extended stored procedure is not available (the default).
1, which indicates that the SQL Server agent extended stored procedure is available.
This setting takes effect immediately, without stopping and restarting the server.
Example

sp_configure ' show advanced options ', 1; Goreconfigure; Gosp_configure ' Agent XPs ', 1; Goreconfigurego
