DOCUMENT:Q133202 08-AUG-2001 [winnt] TITLE :Windows NT File System Security and WWW Browsing PRODUCT :Microsoft Windows NT PROD/VER: OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Server version 3.51 ------------------------------------------------------------------------------- SUMMARY ======= When you use Windows NT as your HyperText Transfer Protocol (HTTP) Server, you cannot effectively use Windows NT file system (NTFS) permissions to secure access to files when they are accessed from a World Wide Web browser. MORE INFORMATION ================ If your HTTP Server has HyperText Markup Language (HTML) documents on an NTFS-formatted drive, the document files need to have permissions assigned to the SYSTEM account to allow client Web browsers to read the files. If you use a Web browser to access a file that has been given the No Access permission for SYSTEM, or does not have any access permissions, an error similar to the following appears: HTAccess: Error accessing "http://server/file.htm": "HTTP: File/directory does not exist" The exact error message text varies depending on the client browser software. As long as the file has the Read permission granted to the SYSTEM account, which is part of the Everyone group, Web browsers will be able to read the file. This information is based on the HTTP Server version 0.94 from the European Microsoft Windows NT Academic Centre (EMWAC) and NCSA Mosaic for Windows version 2.0 Final Beta.
