I have been asked quite a few times on forums about linked server, especially on login mapping options of linked server.



* A clear explanation on login mappings can be found here.
* If you are new to linked server,then a good intro on linked servers can be found here.

Also, if you are using Windows authentication, and having problems with logins and authentication, and look some details about SPN registration and delegation settings refer here.
