I am running SQL Server 2012 on a server (server 1) and have set up a job to run a stored procedure which will summarize data from a series of tables and update a table on a linked server (server 2) which is also SQL Server 2012. I can successfully run the stored procedure on it's own, but when the scheduled job runs, I get the following error:

Executed as user: NT AUTHORITY\NETWORK SERVICE. The OLE DB provider "SQLNCLI11" for linked server "" reported an error. Authentication failed.
[SQLSTATE 42000] (Error 7399) Cannot initialize the data source object of OLE DB provider "SQLNCLI11" for linked server "".
[SQLSTATE 42000] (Error 7303) OLE DB provider "SQLNCLI11" for linked server "" returned message "Invalid authorization specification".
[SQLSTATE 01000] (Error 7412). The step failed.,00:00:00,16,7412,,,,0

I suspect this is a security issue, but cannot find the settings that will let me run this.

    Check which account the SQL Server Agent Service is running under (using SQL Server Configuration Manager on the server).

The SQL Server 2012 builds that were released after SQL Server 2012 was released. You must apply a SQL Server 2012 hotfix to an installation of SQL Server 2012. The fix for this issue was released in Cumulative Update 1 for SQL Server 2012. For more detail please read: https://support.microsoft.com/en-in/help/2652582/fix-invalid-authorization-specification-error-message-when-you-run-the


Include the local login "NT AUTHORITY\NETWORK SERVICE" enter image description here

  • Doing that will allow any remote service running as the Network Service account on the same domain to run anything including a DROP DATABASE command against the linked server. I would highly recommend not adding the NT AUTHORITY\Network Service to your SQL Server like this.
