SQL Server blocked access to procedure 'dbo.sp_sqlagent_get_startup_info' 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', see "Surface Area Configuration" in SQL Server Books Online.

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

RECONFIGURE

I was getting a "the user cannot access resource due to not having rights on Locked in Memory"

The solution to the problem is:

On the Start menu, click Run. In the “Open” box, type gpedit.msc.
On the “Group Policy” console, expand Computer Configuration, and then expand Windows Settings.
Expand Security Settings, and then expand Local Policies.
Select the User Rights Assignment folder.
In the right details pane, double-click Lock pages in memory.

Add the relevant account to the permissions list on this policy, the account should be the start up account for the SQL Service
