error 7416 access to remote server is denied

hey guys i am getting this error on my link server it is sqlsqever to sqlserver link

error 7416 access to remote server is denied because no loggin mappings exists

How did you map db user to remote sql login in linked server?

I got it the problem was the connection not to be made if you are not on the list of the mapped users.

Solution:I choose the option connection be made using the following security context: and i created a log in with permissions she wanted on the that server.

Thank u guys.
