Securing a Web Site Using NTFS Special Permissions

  • Artigo

Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1

With NTFS permissions, you can assign special permissions to groups or users. Special permissions are permissions on a more detailed level. For better management, you should assign broad-level permissions to users or groups, where it is applicable. For descriptions of permissions, see "Permissions for Files or Folders" in Help and Support Center for Windows Server 2003.

Important

You must be a member of the Administrators group on the local computer to perform the following procedure or procedures. As a security best practice, log on to your computer by using an account that is not in the Administrators group, and then use the runas command to run IIS Manager as an administrator. At a command prompt, type runas /User:Administrative_AccountName "mmc %systemroot%\system32\inetsrv\iis.msc".
