We are operating in an virtual environment with the CRM installed on a server. The development is being done from a workstation with Visual Studio 2003. I have checked the settings in the web.config and c360.config. The code works ok if copied to the server and run from there.

Can anyone provide ideas as to what may be causing this?

I also have an 401 error, but it says that it's not WebException, but LicenseException, so I gather it may not be IIS settings' fault (which I think are OK).
