calling Business layer

hi

in my ASP.NET project presentation tier is located in machine1 and i want to call businesslayer and DataAccessLayer from machine2 (which are not webservices) in my project.

How to call the this two tier in machine1?

is there any way to call like this?

No. You must either place the BL and DAL on the same machine as your project (because then you'd open up a few flaws on machine 2 when trying to access from machine 1). OR, better, make them web services.
