If you are having problems with the SQL Server Agent you might want to check if Agent Xps are enabled.
Run the following:
sp_configure ‘show advanced options’, ‘1’
This will reconfigure sp_configure to give you a little more detail for the options you want to change
So run: sp_configure
Check the config_value of the Agent Xps, if it is not 1 simply run:
sp_configure ‘Agent Xps’, ‘1’
