Prolly not what you want to hear, but MSN Network Status reports everything available with no known issues. The email clients on my machines have had no trouble polling my Hotmail accounts, and I was able to access all of them via several different browsers, with no difficulties whatsoever just now. It would seem the problem, for once, is not on Micro$oft's end. Have you made any changes to your security settings or to your connection settings, and are you able to access other websites, including
MSN, OK?
