Hi,
I get the following eror when I try to call my WebService (on the local
machine) using another Web application (on the local machine)

System.Net.WebException: The request failed with HTTP status 401: Unauthorized

Any insights on this would be helpful.

Thanks

The web service you are attempting to access requires that the caller
provide its credentials to prove that it should be allowed to access the web
service. You can use this code to send the "default credentials" to the web
service:

Dim myProxy As New localhost.Service1()
myProxy.Credentials = System.Net.CredentialCache.DefaultCredentials

I tried this method and Josh's (set web service with anonymous auth) and
cannot bet either to funtion. I am running on Windows XP Pro, all modules
are within same solution.

Please show the code you are using to create the web service instance.

It works for me (c#). Thanks a lot.

    localhost.Service1 ws=new localhost.Service1();
            ws.Credentials = System.Net.CredentialCache.DefaultCredentials ;
            textBox1.Text=ws.HelloWorld();

Also, If you're not interested in using Windows Authentication in IIS
to secure your web service you can just turn Anonymous Authentication
on for your web service's Virtual Directory:

- Right click on the virtual directory in IIS
- Choose properties from the context menu
- Select the Directory Security Tab
- Click the Edit button in the Anonymous access and authentication
control
- Check the anonymous access box

I am getting the same problem running on Windows XP Pro with the anonymous
auth.
