Yes, although, we're still unsure why it worked.
In the posting above, Jakana set the Windows Account for anonymous access to be the Custom Domain Account. This is done in the properties of the Virtual Directory -> Directory Security Tab -> Edit Button -> Anonymous Access Grouping.
By default, a machine is configured to use IUSR_MACHINE. Jakana set this to DOMAIN\CUSTOM.
