What Is The Default Login Of Mdf Database Created In WVD Express?

Hi,

I have created an asmx web service that deserializes a JSON string and should execute stored procedures in SQL Server Express 2005, the database is a mdf file. I have created a System DSN which works fine, I have allowed the remote connections and TCP/IP and created the firewall exceptions for sqlserver and sqlbrowser. I believe there's an issue with my connection string, I have tried everything and it still won't connect.

I had another running example but that was on a previous install of Windows XP Pro SP1 with login and this asmx web service worked fine. I run Windows XP Pro SP2 without a login now so I guess I can't use Integrated Security=true or Trusted Connection=yes but does anybody know the default login of a database created in Windows Visual Developer Express?

Here's my connection string:

Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|
antanplan.mdf;Integrated Security=SSPI;User Instance=false;UID=sa;PWD=sa"

And here's the error:

System.Data.SqlClient.SqlException: An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections.
