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...


I would put the .mdf file in the default DATA directory, it will probably be something like:

 C:\Program Files\Microsoft SQL Server\MSSQL11.INSTANCE_NAME\MSSQL\DATA 


C:\Program Files\Microsoft SQL Server\MSSQL11\MSSQL\DATA

The sever probably can't find the log file, this script rebuild the log (.ldf) file.

CREATE DATABASE AdventureWorks2012_Data
ON (FILENAME = N'C:\Program Files\Microsoft SQL Server\MSSQL11.INSTANCE_NAME\MSSQL\DATA\AdventureWorks2012_Data.mdf')

While creating a new database provide database path outside users folder . So , lot of permissions related issue are solved
