We intent to use SQL Server Express 2008 in conjunction with Ultidev Webserver to distribute locally installable versions of a web application. We have set up a connection to a local database file. Anything runs fine, if a guy with admin priviledges sits in front of the computer and runs the app from Visual Stuido 2010 debugger. So far, so nice.

If the projekt is compiled and packed, then locally installed on the same machine and the same guy tries to run the app, an error appears while attaching the MDF to SQL Express instance (pls. apologize for german error text):

Die CREATE DATABASE-Berechtigung wurde in der 'master'-Date!!! counterfeit illegal fraudulent low-quality spam !!!nk verweigert

The connection string used is as follows ('.\project.mdf' is programmatically expanded to full qualified path name)

connectionString="Data Source=(local)\SQLEXPRESS; AttachDBFilename=.\project.mdf; Initial Catalog=Project; Integrated Security=true;"

I guess, that the error results from the different security context, the webserver runs in. Now, I'm a bit confused, how to enable the web server to attach my database file to SQL Express instance.

Any ideas are welcome.
