In VB (VS2005), I have developed a web service that represents my business
and data layers. I have a written a windows client that consumes the web
service. I am having trouble, on my customer's network, handling some
properties of a class returned by the web service while debugging.

My development machine is Windows XP, VS2005, SQL Server 2005. Running the
web service as localhost on my machine everything works great.

On my customer's network, the client application is installed on Windows XP
and consumes the web service that sits on a Windows Server 2003 box and,
again, everything works great.

However, when I attempt to step through the code, or even just run the client
application from the VS IDE on the server (terminal server box) this
particular object is returned with some of the properties populated but a
couple of the properties not. I suspect they are not being serialized.

The class in question represents a comprehensive view of a person with
typical properties like last name, first name, effective date, etc but a
couple of the properties are datatables of addresses and phone numbers. These
properties, when running from the VS IDE, are returned as nothing even though
the PCs with the client app actually installed and that point to the same web
service instance are receiving the addresses and phone numbers just fine.
What's the deal. In addition, I am not able to step into the web service when
debugging although I have no difficulty when debugging on my own machine.
This last issue may or not be related to the first. Please help!
