There was an Authentication problem the other day but it did not interupt my Messenger but supposedly did effect quite a few people. Since I turned my computer on this morning around 10:00 it's been down completely. The .NET Service is down obviously and this effects any .NET log in sites and effects both the Windows Messenger and MSN Messenger log ins not to mention several other sites on the net that use the .NET Services... Could it be an upgrade to the system? Maybe finally and upgrade for us Windows Messenger folks instead of that MSN Messenger crap? Just a few thoughts... LOL.
