Can somebody assist. I build this code on a dev laptop and copied across
the entire code to a Windows 2003 server with 1.1 framework. It is basic
ASP.NET that uses web service for SQL Server 2000 DB access.

The code works fine on my dev laptop, just not on the non dev machine.

Here is the full error page:
