Limitations and Restrictions

  • SQL Server Agent proxies use credentials to store information about Windows user accounts. The user specified in the credential must have "Log on as a batch job" permission on the computer on which SQL Server is running.

  • SQL Server Agent checks subsystem access for a proxy and gives access to the proxy each time the job step runs. If the proxy no longer has access to the subsystem, the job step fails. Otherwise, SQL Server Agent impersonates the user that is specified in the proxy and runs the job step.

  • If the login for the user has access to the proxy, or the user belongs to any role with access to the proxy, the user can use the proxy in a job step.



Only members of the sysadmin fixed server role can create, modify, or delete proxy accounts.

Using SQL Server Management Studio

To modify a SQL Server Agent proxy

  1. In Object Explorer, click the plus sign to expand the server that contains the SQL Server Agent proxy account that you want to modify.

    -- Disables the proxy named 'Catalog application proxy'.  
    USE msdb ;  
    EXEC dbo.sp_update_proxy  
        @proxy_name = 'Catalog application proxy',  
        @enabled = 0;
