SQL Server Error Msg 7416 – Access to the remote server is denied because no login-mapping exists

In this blog post, let’s learn about the error message “7416 – Access to the remote server is denied because no login-mapping exists.” in Microsoft SQL Server, the reason why it appears and the solution to fix it.

SQL Server Error Message

7416 – Access to the remote server is denied because no login-mapping exists.

Reason for the Error

The SQL Server Error Msg 7416 occurs when a user tries to access a linked server, but the user has not been granted access to the linked server. This error message can also appear if there is a misconfiguration in the security settings for the linked server. Specifically, the error message states “Access to the remote server is denied because no login-mapping exists.”

Some examples of what can cause this error message to appear include:

1. The user attempting to access the linked server does not have the necessary permissions to do so.
2. The linked server configuration settings are incorrect or the security settings are misconfigured.
3. The server hosting the linked server is not available, causing a connectivity issue.

Solution

Here are some possible solutions to fix the SQL Server Error Msg 7416:

1. Grant the necessary permissions: Check the permissions of the user trying to access the linked server. Ensure that the user has been granted the necessary permissions to access the linked server. You can do this by adding the user to the security settings of the linked server.
2. Check the linked server configuration settings: Verify that the linked server configuration settings are correct and that the security settings are properly configured. Check to see if the login mapping exists and if not, create one.
3. Verify connectivity: Ensure that the server hosting the linked server is available and that there are no connectivity issues.

To illustrate a solution to this error, here is an example:

Let’s say we have a SQL Server instance named “ServerA” and a linked server named “LinkedServerB” that is hosted on another SQL Server instance named “ServerB”. When attempting to access the linked server from ServerA, we receive the error message:

“Msg 7416, Level 16, State 1, Line 1 Access to the remote server is denied because no login-mapping exists.”

To fix the error, we can try the following steps:

1. Connect to ServerB and verify the login-mapping exists for the user trying to access the linked server.
2. If the login-mapping does not exist, we can create one using the following T-SQL command:

EXEC sp_addlinkedsrvlogin 'LinkedServerB', 'false', NULL, 'username', 'password'

1. Note that the “username” and “password” parameters should be replaced with the actual username and password of the user trying to access the linked server.
2. Verify that the permissions for the user trying to access the linked server have been granted on ServerB. We can do this by checking the security settings of the linked server on ServerB.
