i have a problem,i have a db was made on sql server 2000 with a user called 'mattya',and a password.and my application was made in windows NT,with ASP.NET 2003.

the problem is i install windows xp,ASP.NET 2005,SQL SERVER 2005 and i want to publish my application on local iis but there is a message appear to me that 'mattya is not associated with trusted sql server connection' and i do not know why?
