Points of My Scenario
1. I am admin of a Reporting Services (2008 R2) website that has been working until this morning.
2. Issue: users are now unable to authenticate/access it by its FQDN (fully qualified domain name) - it keeps prompting for credentials
3. When users type IP address instead of the FQDN, they can access the website
QUESTION: How can I resolve this issue so that users can once again access it via the FQDN?
