Make certain your time, date, and /time zone/ settings are correct.

IE Tools>Internet Options>Privacy>Edit> type in

hotmail.com
passport.net
(msn.com)

and Allow All Cookies for each domain, in turn.

Temporarily disable your firewall, any "system" tools (NSW, NIS, anything by
Norton or McAfee) and pop-up/ad blockers to see if they're interfering.

IE Tools>Internet Options>Advanced>HTTP 1.1>toggle between the two options.

IE Tools>Internet Options>Security>[zone in OE runs; should be Restricted
Sites]>Custom Level>User Authentication>Logon>toggle between Anonymous
Logon, Automatic Logon with Current Username and Password, and Automatic
Logon only in Intranet zone. (Anonymous Logon works for me, but YMMV)

Resetting either or both of the above Tabs to the defaults might help, too.
