What's the difference between IIS_IUSRS and IUSR?

What's the difference between IIS_IUSRS and IUSRS? When I granted permissions for IUSR to web.config it worked, but not when I granted permissions to IIS_IUSRS.

The documentation, Understanding Built-In User and Group Accounts in IIS 7, from Microsoft explains it well.

In summary, IIS 7 and above offer the following:

  • The IUSR built-in account replaces the IUSR_MachineName account.
  • The IIS_IUSRS built-in group replaces the IIS_WPG group.

One thing I noticed is that in order to download pdf file from a url, I need to set security permission to iis_iusrs, not iusr.
