In this blog, we are going to discuss an error that we have recently encountered while using a linked server. Moreover, we will discuss fixing Linked Server ERROR 7416 – Access Denied as No Login-Mapping Exists.
What do we understand by SQL Server?
SQL Server is a Relational Database Management System by Microsoft. It is used as a central location to save and get the data needed for applications. This product is made for the basic function of storing recovering data as required by other applications. It can be run either on the same system or on another across a network.
There are different flavors of SQL Server, which offer various features as per user requirements. These products, also called Editions, include:
- Enterprise: Usually Built for large organizations with complicated data requirements.
- Standard: It is helpful for departments within organizations.
- Workgroup: This usually Includes a reporting module for synchronizing data remotely.
- Developer: This is Single-use installation, meant for development and testing of applications
- Web: This is usually for small businesses looking to build web applications
- Express: This is a free edition meant for learning and education
- Compact: Another free option which is suitable for stand-alone applications
- Evaluation: This is a Trial version that is only valid for a short time period.
A remote access server (RAS) is a type of server that gives a suite of services to remotely connected users over a network or the Internet. Remote server functions as a remote gateway or central server that connects distant users with an organization’s internal local area network (LAN).
A RAS contains specialized server software which is used for distant connectivity. This software is developed to provide authentication, connectivity, and resource access services to connecting users.
A RAS is installed within an organization and directly linked with the organization’s internal network and systems. Once linked with a RAS, a user can fetch his or her data, desktop, application, print and/or other supported services.
SQL Server Management Studio
SQL Server Management Studio permits you to generate and control your databases as well as administer your SQL Server configuration.
Tasks you can perform with SSMS include:
- Generate, modify & delete databases and database objects such as tables, views, stored procedures etc
- Query your databases
- Generate and maintain user accounts and roles
- Generate and maintain backups (either manual or scheduled)
- Allows to import and export data from/to other databases
- Allows to replicate databases across multiple machines
SSMS permits you to do most tasks either systematically or via the GUI. For example, you can generate a database by right-clicking and selecting New Database, or you can run a SQL script to generate it by clicking.
Receiving Linked Server ERROR 7416 – Access Denied as No Login-Mapping Exists
While dealing with security and after altering some level of access and permission of some logins, we have received an error message while accessing data through linked servers with some logins which was working earlier. Here is the text of the error message.

How are we supposed to Fix Linked Server ERROR 7416 – Access Denied as No Login-Mapping Exists?
Finally, we were able to find the solution to this error. We have made a few changes in the linked server and used the following script to fix this error. We have added a login to linked server which has an issue to access it. Below is the following script and you just need to change your username in place of ‘myUser’ and appropriate server\instance name.
@server = N’LinkedServerName’,
@srvproduct = ‘MS SQL Server’,
@rmtsrvname = N’LinkedServerName’,
@locallogin = NULL ,
@useself = N’False’,
@rmtuser = N’myUser’,
@rmtpassword = N’*****’
