DOCUMENT:Q154952 08-AUG-2001 [iis] TITLE :Remote Admin Can Access a File for Which Everyone Has No Access PRODUCT :Internet Information Server PROD/VER:winnt:1.0,3.51 OPER/SYS: KEYWORDS:kbnetwork ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Server version 3.51 - Microsoft Internet Information Server 1.0 ------------------------------------------------------------------------------- SYMPTOMS ======== An administrator from a remote client running a browser that supports NTLM authentication is able to access a file for which 'everyone' has no access. Example: The file \inetsrv\wwwroot\samples\disclaim.htm has permissions set for everyone as no access. The Server is configured for Anonymous Authentication and Windows NT Challenge/Response Authentication. A remote client running the browser can do NTLM authentication. Access the url http://IIS-Server/samples/disclaim.htm Internet Information Server IIS will let you view the file after a sequence of NTLM challenge/response messages, if you are an administrator on the server computer. If the user logged on to the remote client is not an administrator on the server, then access is denied. Also, if you run the browser locally on the IIS computer while logged on as an administrator and try to access the same URL, you get the correct error message: Error: Access is Denied. RESOLUTION ========== Obtain the fix referenced below, or upgrade to Windows NT 4.0. STATUS ====== Microsoft has confirmed this to be a problem in Windows NT version 3.51.
