I've finally got rid of the error I was having before, I think it was due to me copying lines from my previous web.config. Now i'm having problems of it not showing any drives in the Extended Version but they show in the basic version. I have double checked that the MIME type has been added correctly.
I'm am using IIS 7.
Can you shed any light?
Are you running on HTTPS?
I did try to get https working but couldn't manage it on IIS7. Do you think there may still be bits left from before?
I've attached a screenshot of what is shown when I click on extended version.
HAP+ needs HTTPS to work with the extended my computer browser/User Card
