Problems calling 32-bit web service from 64-bit client?

P: n/a
I have a web service (.NET 2.0) that defines a method with two input
parameters. Both of these input parameters are defined as "int". This web
service is running on a 32-bit machine. There is a client that is calling
this web service method. The client is running on a 64-bit machine (written
in VB). It declares the two input parameters to be LONGs (64-bit) and is
passing these LONG values into the web service that defines these as int.
Will this pose a problem? The customer (client side) is saying this web
service method is not working, but they do not get any errors and no
exceptions are thrown. I am wondering if the fact that the web service method
defines these parameters as 32-bit int but the client is passing them over as
64-bit longs may be causing the problem.

Can anyone confirm this? What is the expected behavior in this situation?

Thank you for any suggestions.
