Troubleshooting - Getting Error Invalid authorization specification in SQL Server.

Problem Description:

I am trying to create Linked Server on SQL Server.

QODBC Test Tool connects successfully to QREMOTE on QuickBooks Server.

Setting up the Linked server - I get this error:

An exception occurred while executing a Transact-SQL statement or batch. (Microsoft.SqlServer.ConnectionInfo)

The OLE DB provider "SQLNCLI10" for linked server "QREMOTELINK" reported an error. Authentication failed.

Cannot initialize the data source object of OLE DB provider "SQLNCLI10" for linked server "QREMOTELINK".

OLE DB provider "SQLNCLI10" for linked server "QREMOTELINK" returned message "Invalid authorization specification". (Microsoft SQL Server, Error: 7399)

So, I'm out of ideas.

Please tell me how to get rid of this issue. 

Solution:

The message “Invalid authorization specification” means that linked server settings to connect to the server are incorrect.

Please verify the below listed linked server property & test again.

1. Please ensure that you have selected the correct provider, Microsoft OLE DB Provider for ODBC Drivers instead of any other providers.

2. In the security tab, please make sure that you have selected Be made without using a security context option.
