Outlook using wrong username to authenticate POP3

I have a client using Outlook configured for (Internet
Mail Only) to access my POP3 server, from a Windows2000
Professional workstation.

When he attempts to receive email, he gets the logon popup
and has to enter his password, even through the checkbox
to remember password is set in the account profile.

Looking in the my servers event viewer is see a 680 and a
529 Event with logon failure.

The funny thing is it's trying to logon using his machine
username not his POP3 account username.

What is causing Outlook to try using his machine username
instead of the user name in the internet account?

Logon attempt by:
MICROSOFT_AUTHENTICATION_PACKAGE_V1_0

There have been several issues with passwords not being retained with
Outlook. Here are some of the known solutions:

For Outlook 2000 or 2002 on Win 98, NT, or 2000:

For Outlook 2000 on Windows 2000:

For all Outlook versions on Windows XP (note, this article is written for OE
but the solution applies to Outlook as well. Just ignore the parts that

Does he have Secure Password Authentication (SPA) checked for his POP3
account? That will try to use the machine/domain logon credentials, which
will of course fail.
