How to resolve : Agent XPs disabled

You may have seen this sentence in front of your SQL Server Agent in SSMS. and so you can’t start your SQL Server Agent ( maybe only with Network Service account )
You can enable Agent Xp’s in sql server 2005.  I think you’d better first create a Login and give proper roles to the user who run this service ( in my case Network Service with sysadmin role ). Then  run the below query in management studio to enable agent xp’s.

sp_configure 'show advanced options', 1;

GO

RECONFIGURE;

GO

sp_configure 'Agent XPs', 1;

GO

RECONFIGURE

GO

Use the Agent XPs option to enable the SQL Server Agent extended stored procedures on the server. When this option is not enabled, the SQL Server Agent node is not available in SQL Server Management Studio Object Explorer.

When you use the SQL Server Management Studio tool to start the SQL Server Agent service, these extended stored procedures are enabled automatically.

Management Studio Object Explorer does not display the contents of the SQL Server Agent node unless these extended stored procedures are enabled regardless of the SQL Server Agent service state.

The possible values are:

• 0, indicating that SQL Server Agent extended stored procedures are not available (the default).
• 1, indicating that SQL Server Agent extended stored procedures are available.

The setting takes effect immediately without a server stop and restart. You can find more about SQL Server Agent and Agent XPs option here.
