sign-in name does not exist or incorrect password

I am having the exact same message pop up when Windows
Messenger (which came with WinXP) tries to sign-in when I
go online. After auto sign-on doesn't work, I try to sign
in again. After that doesn't work, a box pops up and I
retype my password (and ask it to save it) and then it
usually lets me on. However, when I go online the next
time, I have the same problem. It would be appreciated if
someone could help us on this. Thanks
