So I've spent most of the day trying to figure out why a MOSS 2007 site hosted on one of our servers will display fine to some client computers while others get prompted for username/password three times and then dumped to an empty white webpage.
I've already gone through and disabled the loopback checking and that didn't change anything.
I've tried using both Firefox and IE.
I've tried various versions of IE (6 and 8)
I've tried adjusting the security settings for Internet Explorer.
I've tried adding the SharePoint site URL to trusted sites.
I've tried setting IE to use "Automatic logon with current username and password"
I've made sure that the site authentication in IIS has 'Windows Authentication' enabled and 'Anonymous Authentication' disabled.
I've tried every possible solution I have managed to find, but none of them seem to work and it's left me frustrated and desperate.
What can I do to fix this or at least more accurately diagnose the problem?
