What's the size of the .mdf?<br />
You can always try to detach and attach it again. Maybe something went wrong at the first time.

Very small database with 2 tables and less than 100 rows each.<br />
In the Security, my login, User Mapping, I can't give my self any permission except fore &quot;Connect Sql&quot;. &nbsp;<br />
Why this so? &nbsp;Is it because this database wasn't originally created on my PC?

I attached to a database that was sent to me in form of mdf and log files. &nbsp;I put these 2 files in the sql 2012 express' data folder. &nbsp;I then was able to attach to the file. &nbsp;It's just odd that the database would show up with name as c:\.....\its-database-name<wbr /> in Sql Management Studio. &nbsp;It doesn't just show the database name. <br />
<br />
I am able to open the database tables in Management Studio.<br />

where can I enable remote connection? &nbsp;I am not able to use C# code to open this database.

Is there access restriction to attached database?
