Trust Conecction

I have a project in visual basic express that It connect with a sql 2005 express database. When I execute the project in the pc that have installing the sql, there´s no problem with it, but when I use a virtual machine to execute, there´s a problem with the sql connection.

The follwing is my sql connection:

Data Source=USERSQLEXPRESS;Initial Catalog=WORKFLOW;Integrated Security=True;Persist Security Info=True;User ID=sa

and y try with this:

Data Source=USERSQLEXPRESS;Initial Catalog=WORKFLOW;User ID=sa; password=admin13;



This connection are usable for the local machine but when I execute the program in other virtual pc there´s the following error: The user 'sa' is not associeted with a trusted connection SQL Server

System.InvalidOperationException was unhandled
Message="An error occurred creating the form. See Exception.InnerException for details. The error is: Error de inicio de sesión del usuario 'sa'. El usuario no está asociado a una conexión de SQL Server de confianza."
