We are having a problem where one user is unable to authenticate using Windows Authentication. The site is configured to allow "All Users" to access the website and I have confirmed that this user is a member of the "Domain Users" group in AD.
Looking at this users group membership side by side another user, they are identical. However if I copy the user and test with the new account, it also can't use the windows auth.
Any help at all in figuring out why just this one user can't authenticate would be greatly appreciated.
I apologize if I left any important details out; I'm a developer and I don't know much about server administration or networking. The biggest problem is that I don't know the right question to ask to debug this thing I'm sure.
Update, from the server log on this failure:
Failure Information: Failure Reason: Unknown user name or bad password. Status: 0xc000006d Sub Status: 0xc000006a
I am 100% certain the username/password are correct.
