VB.Net 2005 Cannot Login With SQLAuthentication

I have a VB.net windows forms application that is a front-end to a SQL Server databse. Using ado.net 2.0 I am able to login to the database with Windows Authentication no problem. However, when attempting to use SQL Authentication the log in fails with the following message: "Login failed for user 'dan'. The user is not associated with a trusted SQL Server connection"
Here is the connection string being used for SQL Authentication (fails): "Provider=SQLOLEDB;Server=SERVER2006\SQLEXPRESS;Database=TestDB;Uid=dan; Pwd=1111"  I must be able to use SQL Authentication for security reasons. Please help with this problem. Thank you.

BTW:Here is the database connectioon string that works in Windows Authentication (succeeds): "Provider=SQLOLEDB;Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=TestDB;Data Source=SERVER2006\SQLEXPRESS"

One more comment. The above connection string actually should say "User ID" (instead of Uid) and "Password" (instead of Pwd). I believ this does make a difference.

"ADOConnectionString" value="Provider=SQLOLEDB;Persist Security Info=False;Initial Catalog=Database;Data Source=SERVER2006\SQLEXPRESS;User ID=dan;Password=1111"
