"Failed to read IIsWebSite table. (-2147023728)"

The status of the install is "Status: Committing IIS Metabase Transaction"

This only appears to happen if I have more than one website and each website is configured to use a specific IP address, rather than "(All Unassigned)".

I've tried all sorts of combinations but I just can't seem to find a way to install the Customer Interface onto a second website within IIS.  This is required as we are hosting the portal website on the same machine, on Port 80, but using a second IP address.  I even tried to install it to a website using a custom ip address (8066).

Help!!
