Hi, I'm very new to web services so I'm not too sure if what I'm trying to do
is possible.

I have a C# windows application that compacts upto 6 MS access databases. A
form is presented to the user who chooses which dbs to compact.

If I wanted to have a common business logic layer that would supply both a
new ASP.Net web page and the existing windows form, is the idea to move the
methods from the windows app into a web service? Or is there an easier way?

Webservices = Interoperability = non .Net clients

You are taking about a .net form and a .net web app sharing logic, all
you need is a .net dll. If the compacting logic needs to run from a
different computer than the one hosting the web page or the web form
then use .net remoting (binary serialization hosted in IIS) for the
dll.
