As a part of our Server Management Services, we help our Customers to fix SQL related errors regularly.

Let us today discuss the possible causes and fixes for this error.

What is SQL server error 7416 ?

Altering the level of access and permission of logins at times changes the way in which they worked earlier. Likewise, it may trigger the 7416 error message while accessing data through linked servers with some logins which was working earlier. A typical error message looks like:

SQL server error 7416

This error occurs due to a number of reasons including those given below:

1. Windows operating system is corrupted
2. Unrestricted startup entries
3.Registry mistakes
4.Hardware decline
5.Shattered files
6.Needless program installations
7.Linked server security settings

How to fix SQL server error 7416 ?

The most common reason for the no login-mapping error is the settings in the security tab for the linked server. It generally triggers when the settings for the not defined logins is set to be “not be made” as shown in the screenshot below:

Changing this to the second or third option will help to fix this error.

Another scenario that triggers this message is using a username instead of a login to execute commands. This can cause the error when the user is not mapped to any login. The solution here would be to provide the user id with the connection string.

Further, when we have several applications running, you may observe crashes and freezes. At times adding a new login to the linked server could help to fix the error. A sample script for the same is given below. Replace username in place of ‘myUser’ and appropriate server/instance name.

Use master
GO
EXEC master.dbo.sp_addlinkedserver
@server = N’LinkedServerName’,
@provider=N’SQLNCLI’,
@srvproduct = ‘MS SQL Server’,
@provstr=N’SERVER=ServerName\InstanceName;User ID=myUser’
EXEC master.dbo.sp_addlinkedsrvlogin
@rmtsrvname = N’LinkedServerName’,
@locallogin = NULL ,
@useself = N’False’,
@rmtuser = N’myUser’,
@rmtpassword = N’*****’
