DataSource Controls :: Completely Stuck / Trying To Deploy It To WS 2k3?

I've written a desktop application using VB.NET and SQLEXPRESS. Now I am trying to deploy it to WS 2k3. But getting positive results wiht SQLE is proving difficult. Here is the connection string I am using:

connectionString = "Data Source=.SQLEXPRESS;" + "AttachDbFilename=" + DBPath + ";" + "Integrated Security=True;" + "Connect Timeout=30;" + "User Instance=True"

The problem is the results I get from the setting of 'User Instance'. Like it is, it loads a unique stance of SQLE, which is fine. But the instance just keeps eating memory. I tried limiting memory with sp_configure, but nothing happened. It just keeps growing. If I exclude 'User Instance', it uses the SQLE service running on my machine. It ignores the memory limitation, but eventually settles and stops growing.

Those results came from working on my local machine.When I put it on 2k3, I get the same results with User Instance = True; runaway memory. With User Instance = False, I start getting the 'attempt to attach an auto-named database failed' message. So now I am stuck. I would like to go with the 'User Instance = true' option, but I don't know how to deal with the runaway memory. If all else fails, I could use the =False option, but I just can't get 2k3 to allow.
