when I use asmx service and SSRS report service I am getting "The request failed with http status 401: unauthorised" - asp.net

Question

I was trying to call report related service (asmx) from my asp.net web application by running locally.
Then an exception happened saying. The request failed with http status401:unauthorised.
In my analysis I understood the issue caused due to below code
SSRSWebService.ReportingService2005 rs = new SSRSWebService.ReportingService2005();
rs.Credentials = new MyReportServerCredentials().NetworkCredentials;
and
Uri reportUri = new Uri(ConfigurationManager.AppSettings["ReportServerManagement.ReportingService2005"]);
this.rptViewer.ServerReport.ReportServerCredentials = new MyReportServerCredentials();

Answer 1

In my detailed analysis I understood that the issue was because of the credential set up in serviceObject.credential OR ServerReport.ReportServerCredentials was wrong. This can be rectified in two different way either by setting credential to default with below code
rs.Credentials = System.Net.CredentialCache.DefaultCredentials;//"rs" is report object
Or locate below code and set up proper authenticated user credential in the code
public WindowsIdentity ImpersonationUser
{
get
{
// Use the default Windows user. Credentials will be
// provided by the NetworkCredentials property.
return null;
}
}
public ICredentials NetworkCredentials
{
get
{
// Read the user information from the Web.config file.
// By reading the information on demand instead of
// storing it, the credentials will not be stored in
// session, reducing the vulnerable surface area to the
// Web.config file, which can be secured with an ACL.
// User name
string userName =
<<AccurateUserName;>>
// Password
string password =
<<AccuratePassword;>>
// Domain
string domain = <<AccurateDomainName;>>
return new NetworkCredential(userName, password, domain);
}
}
In order to check whether which user has the access, we need to type service url ending with asmx (http:/MyServiceHostedServer/MyService.asmx) in a web browser. It will prompt a user name and password . Give our username as :Domain\Username and password.If we are able to see wsdl xml file then that user has the access.
