Allow Anonymous Access to the Password Reset Portal

Question

How do I go about enabling Anonymous Access to the Password Reset Portal?
The following instructions don't seem accurate anymore.  Has this setting changed with Sharepoint Services 3.0 SP2?
When I click on "Settings" in Step 4 the only option displayed is "Permission Levels".
Allow Anonymous Access to the password reset portal
In this procedure you will configure the portal to allow Anonymous Access to users who need to reset their passwords.
To allow anonymous access to the password reset portal
Log on to the password portal (http://<portal hostname/PasswordPortal) as an administrator.
On the top right hand side of the portal homepage click Site Actions, and then click Site Settings.
Under Users and Permissions click Advanced Permissions.
On the Permissions page, click Settings, and then select Anonymous Access.
Under Anonymous users can access, select Entire Web site, and then click OK.

Yes, that was very helpful.  Thanks! 
Just in case that site dissapears and someone else needs this info, here it is:
If you don’t see the “Anonymous Access” menu option in the “Settings” menu, it might not be turned on in Central Admin/IIS. You can manually navigate to “_layouts/setanon.aspx” if you want, but the options will be grayed out if it hasn’t been enabled in IIS
First get to your portal. Then under “My Links” look for “Central Administration” and select it.
In the Central Administration site select “Application Management” either in the Quick Launch or across the top tabs
Select “Authentication Providers” in the “Application Security” section
Click on the “Default” zone (or whatever zone you want to enable anonymous access for)
Under “Anonymous Access” click the check box to enable it and click “Save”
NOTE: Make sure the “Web Application” in the menu at the top right is your portal/site and not the admin site.
You can confirm that anonymous access is enabled by going back into the IIS console and checking the Directory Security properties.
Now the second part is to enable anonymous access in the site.
Return to your sites home page and navigate to the site settings page. In MOSS, this is under Site Actions – Site Settings – Modify All Site Settings. In WSS it’s under Site Actions – Site Settings.
Under the “Users and Permissions” section click on “Advanced permissions”
On the “Settings” drop down menu (on the toolbar) select “Anonymous Access”
Select the option you want anonymous users to have (full access or documents and lists only)
Now users without logging in will get whatever option you allowed them.
A couple of notes about anonymous access:
You will need to set up the 2nd part for all sites unless you have permission inheritance turned on
You must do both setups to enable anonymous access for users, one in IIS and the other in each site
