The remote server returned an error: (401) Unauthorized

Vijayakrishna Pondala

Hi,

I am using the following C# code to connect to and download information from
a URL. (The pages are on JBoss server and we are using NTLM authentication
to connect to the server).

----
string url = "http://internal.ourcom pany.com:8010/Page1";
WebRequest wreq = WebRequest.Crea te(url);
//Assign the default logon creadentials.
wreq.Credential s = CredentialCache .DefaultCredent ials;
wreq.Timeout = 1000;
//Get the web response stream
WebResponse wres = wreq.GetRespons e();
----
For some users, this code throws an error saying "The remote server returned
an error: (401) Unauthorized". When the user directly accesses the URL using
IE, he is able to see the information correctly.
Could someone help me out what is causing this error?

Thanks in advance,
Vijaya Krishna P.

This is because the CredentialCache .DefaultCredent ials uses your Windows credentials for authenication which the JBoss server doesn't know anything about

Create a new instance of the System.Net.Netw orkCredentials class (it takes a user id, password and domain) and set the credentials of the web service proxy to that.
