Directory lookup failed when adding sample database to SQL Server 2012 I am trying to add the AdventureWorks sample database to SQL Server 2012, but I get an error message:


  Msg 5133, Level 16, State 1, Line 1
  Directory lookup for the file "C:\Users\A\Documents\SQL Server Management Studio\Data\AdventureWorks2012_Data.mdf" failed with the operating system error 5(Access is denied.).
The error message seems pretty straightforward: Access is denied. You need to make sure the SQL Server service account has adequate permissions on C:\Users\A\Documents\SQL Server Management Studio\Data\, or better yet, move the MDF (and LDF, if it exists) to the default data/log folders for the instance (where this shouldn't be a problem, and which is a better home for your database files anyway).

You can find the default data/log folders by inspecting:

SELECT physical_name FROM sys.master_files;


Any of the paths presented here should be a valid location to use...
