Answer 1

This problem occurs for one of the following reasons:

You are using IIS 7.0 on a computer that is running Windows Vista. Additionally, you configure the Web site to use UNC Passthrough authentication to access a remote Universal Naming Convention (UNC) share.

The IIS_IUSRS group does not have the appropriate permissions for the ApplicationHost.config file, for the Web.config file, or for the virtual/application directories of IIS.
