Invalid username or password error when connecting to ISP

I keep getting an invalid username or password error when trying to connect to my ISP. I have had this account for several years and have no problems from Win 98, only W2k. Sometimes it will work fine. I have two machines that exhibit this same problem. I have removed and reinstalled protocols, DUN, etc.
If it works sometimes but doesn't work other times, it's probably the fault of your ISP. It's possible that they have two different types of dial-in servers, and that each type uses different authentication methods. The next time you have a problem connecting, view the properties for your dial-up connection. Select the Security tab, and check the 'Show terminal window' checkbox. This will allow you to watch the conversation between your computer and the server. Watching it may make the problem apparent. Perhaps your computer doesn't recognize the username prompt, or is issuing the wrong command to start the PPP session.
