I am having the same problem, and so are most of the
employees here... I have three guys out of 20 than can
get in, so what gives?  I am getting an MSN error:
[We were unable to sign you into .NET Messenger Service,
possibly because of a problem with the service or with
your Internet connection.  Please make sure that you are
connected to the Internet.  0x81000301  Click the Help
button to chec the current service status.]  And when I
do click on the help button it doesn't take me
anywhere... It's like that service page is down as
well...  But I'm not seeing millions of posts here
either, so I assume that it isn't down for the world,
just me.  Any help would be GREATLY appriciated.  Thanks,
guys!
