在configure distribution时遇到错误，不能打开sql agent

今天在配置Distribution时，遇到一个错误，不能打开sql agent，详细错误信息如下：

SQL Server blocked access to procedure ‘dbo.sp_set_sqlagent_properties‘ of component ‘Agent XPs‘ because this component is turned off as part of the security configuration for this server. A system administrator can enable the use of ‘Agent XPs‘ by using sp_configure. For more information about enabling ‘Agent XPs‘, search for ‘Agent XPs‘ in SQL Server Books Online. (.Net SqlClient Data Provider)

从网上找到的solution

--To resolve this error, following script has to be executed on the server.

sp_configure ‘show advanced options‘, 1;
GO
RECONFIGURE;
GO
sp_configure ‘Agent XPs‘, 1;
GO
RECONFIGURE
GO

When you run above script, it will give a very similar output as following on the screen.
