Very nearly completed my installation of HAP but I am encountering a small issue.
When I logon to the system, I get an error message saying error 403 forbidden access, however I can navigate manually to the .aspx pages and it says I am logged in and appears to work fine. If I enable Directory Browsing I can see the file structure and load up the .ASPX files from there with no issues.
With Directory Browsing enabled I see no error messages and occasionally I can login fine and get redirected to the default.aspx page with no issues or Directory Browsing, but when I click on the button to access my files I get redirected to the /hap folder and not the \MyFiles\Default.aspx
Make sure that you've set the default file type in IIS to default.aspx
Brilliant, that fixed it!! Spot the IIS Noob, lol!!
