I am not used to work with SQL Server(usually I just use express). I run it on windows server 2008, iis7.

I have attached the database to my sql server. I made a web site in iis7 but I get this error message. 

> 
> Cannot open database "Phaeton.mdf" requested by the login. The login failed.
>  Login failed for user 'NT AUTHORITY\NETWORK SERVICE'.

Connectionstring I use

```
<add key="PhaetonConnectionString" value="Data Source=.;Initial Catalog=Phaeton.mdf;Integrated Security=True"/> 

```

Thanks
