Lily,
Part of modern authentication procedures involves use of the clock on the client
(where you are logging in), and the server (which you are trying to login to).
To prevent replay attacks, the clock on both computers is hashed into the
authentication. If the clock on your computer is off by more than 5 minutes or
so, authentication fails.
This frequently is an issue when daylight savings time day rolls around, twice a
year.
Set the clock on your computer. As precisely as possible. That's usually all
that's required.
