Hi, sorry for the x-post and thanks in advance for any help you can
provide.

I'm attempting to call a .NET 3 web service from a .NET 1.1 rich
client. I've successfully consumed the service in Visual Studio by
adding a static web reference. Unfortunately at runtime I get the
horrible exception attached below.

Is there something I've done that is obviously wrong? Which tools can
I use to investigate this problem further?

Many thanks,

Nick
