MORE INFORMATION
The following tables document the NTFS file system permissions, registry permissions, and Microsoft Windows user rights. This information applies if Microsoft ASP.NET is included as part of the installation suite. This article focuses on the World Wide Web Publishing Service and does not consider other components, such as the File Transfer Protocol (FTP) service, the Simple Mail Transfer Protocol (SMTP) service, and Microsoft FrontPage Server Extensions (FPSE).

Note For the purposes of this document, the IUSR_MachineName account is used interchangeably with a configured anonymous account.

Note 1 You must have permissions to this directory when you use Basic authentication or Integrated authentication and when custom errors are configured. For example, when error 401.1 occurs, the logged-on user sees the expected detailed custom error only if permissions to read the 4011.htm file have been granted to that user.

Note 2 By default, ASP.NET is used as the ASP.NET process identity in IIS 5.0 isolation mode. If ASP.NET is switched to IIS 5.0 isolation mode, ASP.NET must have access to the content areas. ASP.NET process isolation is detailed in IIS Help. For additional information, visit the following Microsoft Web site:

Note In a new default installation of Microsoft Windows Server 2003 with IIS 6.0, the Users group and the Everyone group have Bypass traverse checking permissions. The worker process identity inherits Bypass traverse checking permissions through one of these groups. If both groups are removed from Bypass traverse checking permissions, and the worker process identity does not inherit Bypass traverse checking permissions through any other assignment, the worker process does not start. If the Users group and the Everyone group must be removed from the Bypass traverse checking permissions, add the IIS_WPG group to permit IIS to function as expected.

Note In IIS 6.0, when Basic authentication is configured as one of the authentication options, the LogonMethod metabase property for Basic authentication is NETWORK_CLEARTEXT. The NETWORK_CLEARTEXT logon type does not require the Allow log on locally user right. This also applies to Anonymous authentication. For additional information, see the "Basic Authentication Default Logon Type" topic in IIS Help. You can also visit the following Microsoft Web site:
