The web service you are trying to consume, is it one you have written? It
looks like it is trying to either read or write a log file in c:\program
files\csorder. If it is a standard ASP.NET web service, with default
credentials, the process doesn't have access to that path. If you need to
give it access, you need to explicitly give the account the worker process
runs under access to that directory.

I'm not sure if this helps, but that is what appears to be happening,
