Unable to call the SharePoint Custom web service from another SharePoint Farm

Question

I have deployed a custom SharePoint Web service on Farm A. I am trying to access this Web service from a SharePoint timer job on Farm B. On Farm B, I am creating Class Library project, packaging it (wsp) and then deploying to GAC. The problem is I'm unable to access the Web Service using the following code. TodaysNewSVC is a service reference

      TodaysNewSVC.GetTodaysnewsfromInsite objGetNews = new TodaysNewSVC.GetTodaysnewsfromInsite();
      objGetNews.PreAuthenticate = true;
      objGetNews.Credentials = CredentialCache.DefaultCredentials;
      objGetNews.Url = "http://insite-dev.portal/_vti_bin/todaysnews.asmx";
      DataTable dt2 = objGetNews.getNewsFromInsite(true, true);

//getNewsFromInsite is a WebMethod which returns the DataTable.

Note: Both farms use the same active directory authentication. I have also done the debugging for Timer Job and feature activation and they are working fine. The problem occurs during the call i.e. getNewsFromInsite

The asmx and wsdl files are accessible from Internet Explorer and also from Windows Console application. Here is the code which I use from console application:

            GetTodaysnewsfromInsiteSoapClient objWSClient = new GetTodaysnewsfromInsiteSoapClient();
            objWSClient.ClientCredentials.Windows.ClientCredential = System.Net.CredentialCache.DefaultNetworkCredentials;
            objWSClient.ClientCredentials.Windows.AllowedImpersonationLevel = System.Security.Principal.TokenImpersonationLevel.Impersonation;
            DataTable dt = objWSClient.getNewsFromInsite(true, true);

Here is the error message:

The request failed with the error message:

What is problem-with-page.aspx ? Is it a login or a custom error page ?

If its login page, then your authentication is failing. I doubt if its login page because you mentioned Active Directory authentication.

If its custom error page, the target code is throwing the exception. Are you able to step in to the target code ?
