HTTPWebRequest timeout

Our application is written in C# and uses http remoting technology.
Server and client utilizes http channel for communications.

On some win2k sp4 machines with .Net 1.1 sp1 the client is unable to access
the server even when the server is located on the same machine.

The error does not occur when using tcp channel instead of the http channel.

We traced the problem to HTTPWebRequest using a small test application (see
attachment) that uses the HTTPWebRequest class to get the html content of a
web site page.

When running the project following lines threw an exception (see below)
HttpWebResponse loWebResponse = (HttpWebResponse) loHttp.GetResponse();


The stacked trace for JIT debugger:
************** Exception Text **************
System.Net.WebException: The operation has timed-out.
at System.Net.HttpWebRequest.GetResponse()
at wwHTTP.SimpleHttpWebRequest.cmdGo_Click(Object sender, EventArgs e)

at System.Windows.Forms.ControlNativeWindow.WndProc(Message& m)
at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg,
IntPtr wparam, IntPtr lparam)



Extra details:

No proxy is defined.

All updates from the Microsoft Windows Update website are installed.

We installed Visual studio.Net on the machine and ran the sample project,
the following error was recived:
An unhandled exception of type 'System.ArgumentException' occurred in
mscorlib.dll.
Additional information: Invalid or unsupported code page type.


Any help resolving this issue will be appreciated.
