I have just set up a SharePoint server. I need to change the URL for the site to the FQDN from the hostname. When I do this, the site immediately begins prompting me for credentials. Nothing works. Not even the Farm admin account. I have added the new URL to IE as a trusted site. I have reset IIS. Again, nothing has helped.
When I change back to the original URL, everything works fine. Obviously something is hung up on the old URL, but what? Where??
I have spent two days on this and counting. I am VERY frustrated. This is an ASININE problem. Any help would be appreciated.
