Windows Server 2008 R2 – IIS7.5 – Web site permissions

iis-7.5windows-server-2008-r2

Why when I remove the MACHINENAME\Users group permission set from a websites physical folder and and grant a similar permission set to MACHINENAME\IIS_IUSRS group my website will not start.

Why do I have to grant Read & Execute, List folder contents and Read to the MACHINENAME\Users group physical website folder?

Windows Authentication was enabled on website. Clients who visited the intranet site were granted access via MACHINENAME\Users
