Only members of the sysadmin fixed server role can execute sp_grant_proxy_to_subsystem.

The following example grants the proxy Catalog application proxy access to the ActiveX Scripting subsystem.

USE msdb ;
GO

EXEC dbo.sp_grant_proxy_to_subsystem
    @proxy_name = 'Catalog application proxy',
    @subsystem_id = 2;
GO

B. Granting access to a subsystem by name.

The following example grants the proxy Catalog application proxy access to the DTS package execution subsystem.

USE msdb ;
GO

EXEC dbo.sp_grant_proxy_to_subsystem
