HTTPWebRequest.request.GetResponse fails: remote server re..

I have an asp.net web application which posts a request to another
asp.net web application. I am coding in C# using Visual studio 2003,
with .Net Framework 1.1 on a Wiondows 2003 server (running IIS 6.0.).
In order to have all code running as managed code, I changed existing
code which uses MSXML ServerXMLHTTPClass to post requests to code
using the .Net HTTPWebRequest class. When migrating the application to
the Test web server, IIS appears to prevent access (=no record of the
request in the Windows\System32\Logfiles\W3SVC1 files). I am using
impersonation in the web.config file of the client and 'server' web
applications. The Application needs to be configured in IIS to
'Windows Authentication' only. The impersonated account is a member of
IIS_WPG group an has NTFS permissions to the Applications physical
folder. Even if I open up security (allow everyone). There is no web
proxy issue. Both client and Server applications are at this point
both on the same Test server with the same specs as the development
machine (above).

THE ONLY WAY IT FUNCTIONS IS IF IIS FOR THE APPLICATION ON THE SERVER
HAS 'ENABLE ANONYMOUS' TICKED.

I see a lot of posts on the internet highlighting this problem without
any difinitive answer. Surely, Microsoft wishes the Managed classes to
be used. Why then does there appear to be such a hassle for coders to
use the class to achieve the same result as the MSXML classes?

The code below is what I am using to make the call. Tracing shows that
the call fails when the request is made (GetResponse()).

HttpWebRequest request=null;
Uri uri = new Uri(requestTargetAndQuery);
request = (HttpWebRequest) WebRequest.Create(uri);
request.Method = "GET";
request.Credentials = new NetworkCredential(this.m_User,
this.m_Password);
string result=string.Empty;
using (HttpWebResponse response = (HttpWebResponse)
request.GetResponse())
{
request response.",traceSwitch);
using (Stream responseStream = response.GetResponseStream())
{
using (StreamReader readStream = new StreamReader
(responseStream, Encoding.UTF8))
{ result = readStream.ReadToEnd();
}
}
}

Hopefully someone can point me in the right direction (or let me know
if the Framework class does not have the capability to achieve what I
am trying)

Thanks Grant_S

Hi Grant,

Have you tried using BASIC Authentication and / or Windows Integrated
Authentication to see if this works?
