Hi Experts,
I have this .NET application to be run in an intranet environment. It is configured so that it requires Windows Authentication before you can access the website (Anonymous access is disabled). This website calls a web service (enable anonymous access) and the web service calls the DB. We do have a token-based authentication between the web application and the web service to secure the communication between them.
The issue I'm facing is that when I deploy this to production, I'm having an intermittent issue whereby the communication between the web application and the web service failed. The 401 issue was thrown. This is actually working fine in our QA environment. Is this an issue with Active Directory? Or could it be an isssue with FQDN as mentioned here: http://support.microsoft.com/default.aspx?scid=kb;en-us;896861?
The weirdest thing is that this is happening intermittently when tested in both on the server itself and a remote workstation in my client's environment. But, this is working perfectly in my environment.
OS: Windows Server SP1
IIS 6
.NET 3.5 Framework
Any idea about the 401 (Unauthorized) issue?? Thx for the help...
This is from the log...
