Unable To Attach SQLExpress Database

This is by FAR, the most frustrating problem I have dealt with for a while.

I have a project containing a SqlExpress database that I created in Visual Studio 2005. Everything works perfectly on my development machine. However, upon copying the site up to the webserver, I get an error stating:


An attempt to attach an auto-named database for fileD:ContentwwwFMakerApp_DataClassAd.mdf failed. A database with thesame name exists, or specified file cannot be opened, or it is locatedon UNC share

I have read almost every article/forum post that resulted from a search with google. I also searched these forums, to no avail.

Note - SQLExpress had just been downloaded and installed on the server, so it wasn't being used yet. Server is Windows Server 2003.

Here are the following steps I have already taken:

Used SSEUTIL.EXE to verify that another database of the same name was not already attached
Uninstalled & reinstalled SQLExpress multiple times
Temporarily granted 'Full Control' permissions to 'Everyone' on the site folder to verify that it was not a permissions issue.
Created a very simple website, with a new database, one page - with one listbox control, and a sqldatasource. Got the exact same error. Should rule out a problem with my application.
Tried various flavors of the web.config connection string.
Probably other stuff that I forgot about, but will add if I remember.

The only things I could imagine being wrong are either a problem with my connectionString, or the fact that SQLExpress is installed on C:, and webstuff is on D: (Wasn't able to install SqlExpress to D: for some reason)

Connection String
<connectionStrings>
<add name="ClassAdConnectionString" connectionString="Data Source=.SQLEXPRESS;
AttachDbFilename=|DataDirectory|ClassAd.mdf;Integrated Security=true;User Instance=True"
providerName="System.Data.SqlClient" />
</connectionStrings>




So I have had like 12 strokes today. If anybody could help me get this fixed, I will spread tales of your awesomeness throughout the lands


I have included some extra info below in case it is needed.
Thanks, Adam.
