HTTP Error 401.1 - Unauthorized

Answer 1

Somewhat late in coming, but an alternative that I sometimes forget is time difference. In a domain environment, run "Net Time /SET" to synchronise with the AD Box.

For all of this to work and to ensure security, the domain controllers and clients must have the same time. Windows operating systems include the Time Service tool (W32Time service). Kerberos authentication will work if the time interval between the relevant computers is within the maximum enabled time parameters. The default is five minutes. You can also turn off the Time Service tool and install a third-party time service. Of course, if you have problems authenticating, you should make sure that the time is correct for the domain controllers and the client that is experiencing the problem.
