Create a Linked Server Using a Windows Account in SQL Server

Question

There are multiple applications on SQL Server which I am trying to connect to from a Single SQL Server. Instead of creating multiple SQL User ID we thought of creating a single Windows Service Account and use that to connect to other SQL Servers.

The issue is I dont know if I can configure a Linked Server to take the credentials of a Windows Service account.

Points:

1. Access has been given to the Windows user account
2. SQL Servers are on Different domains

Is there a best approach to read from multiple sources within the organization other than linked servers?

Update:

Please find below code I am trying to use to create a Linked Server:

USE [master]
GO

EXEC sp_addlinkedserver     
     @server=N'serverinstance',   
     @srvproduct=N'',  
     @provider=N'SQLNCLI',   
     @datasrc=N'serverinstance.domain.local'; 

GO

EXEC master.dbo.sp_addlinkedsrvlogin @rmtsrvname = N'serverinstance'
                                , @useself = N'TRUE'
                                , @locallogin = N'Domain\NTAccount' 
                              --, @rmtuser = N'user'
                              --, @rmtpassword = N'pass'
GO

The linked server still fails. I do not want to use any SQL Server User Auth.

Answer 1

我认为您需要在两个域之间建立信任关系，并确保防火墙允许您访问链接的服务器。

Answer 2

It can be either.

Authentication works the same regardless of if you use Sql or NT Domain authentication.
