I am migrating my project from Biztalk 2004 to Biztalk 2006. I have a pc fresh installed with Biztalk 2006 and VS.net 2005 and my old pc is XP SP2, and Biztalk 2004 SP1 with KB 886903 and KB 890673. The application works in Biztalk 2004 but when I put it in Biztalk 2006. It encounters error in the schemas. What do you think I need to include in the Biztalk 2006 machine?
