IIS 6 and windows 2003 anonymous access problem

If you find yourself having the problem where accessing an IIS site from another machine is prompting you for a user/password and you have tried everything here and here and here. Then you could have my problem, which is I changed the password on the IUSR_ account. In this case you need to go and reset the password on the user for windows to something you know, then you need to go each iis website and click properties, directory security, then click edit, where you have checked "enable anonymous access" you need to put your new password in here and click ok. Magically it all works now (only cost me 4 hours of my life)
