Hi

I am trying to access a web service from a desktop app which is running
behind an ISA Server (Windows 2003 network). The desktop app fails with the
message 'The request failed with HTTP status 470: Proxy authentication
required (The ISA Server requires authorization to fulfil the request.
Access to the Web Proxy Service is denied).

The client app is in vb.net and the second line below gives the error;

Dim ws As New com.mydomain.www.MyService
Dim ds = ws.MyWebMethod ' <== This line gives error

Where am I to provide the authentication for the calling app?

Thanks

Regards

Hi John,

I have the same problem, trying to connect to a web service behind a
ISA-Server.

But there is a little hint given when pressing the help button on the
Dialog "Add Web Reference": There is said that you need to "specify
the proxy-server within the URL".
Does anyone know what there could be meant? Do I have to put the url
of the asmx/wsdl-file AND the url of the proxy server together in one
big url ???

Does the site require client authentication? If so add this:

proxy.Credentials = System.Net.CredentialCache.DefaultCredentials;

Second I believe there's also proxy setting if you're behind a firewall. But
if you have the ISA firewall client I don't think you need to set anything.

I have ISA Firewall client but I still seem to need to provide ISA
authentication. I have tried it both from server (no firewall client) and a
client pc (firewall client).

The site does not require authentication.
