great book! i've learned a lot of techniques already and it just continues from chapter to chapter.

however, on chapter 6 (C# Ed.) I get this message when I run the Windows Application:

(An unhandled exception of type 'System.Net.WebException' occurred in system.web.services.dll
Additional information: The request failed with HTTP status 401: Access Denied.)

has anyone encountered this?

I haven't used the web service yet, but you might be seeing a conflict in the authorization setting in web.config.

Try putting the web service in a different IIS application, and give it an authentication mode of None in web.config. Also give it this in the authorization section:
  allow users="*"

A Web service can't use Forms authorization.

i got the idea. what i did was in IIS under Directory Security, i clicked on Anonymous Access (just to test the web service client), then run the application and it worked.

thanks a lot eric.
