Proxy authentication failure

[John]

Hi

I am trying to access a web service from a vb.net 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 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

John,

Did you ask this question in the newsgroup

Microsoft.public.dotnet.framework.aspnet

Not that you have here nochange on an answer however in my opinion do you
have in that newsgroup a better change.
