DOCUMENT:Q161067 21-FEB-2002 [iis] TITLE :IIS FTP RNTO Overwrites Existing Files PRODUCT :Internet Information Server PROD/VER::1.0,2.0,3.0,4.0 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Internet Information Server versions 1.0, 2.0, 3.0, 4.0 ------------------------------------------------------------------------------- SYMPTOMS ======== In the FTP Service included with Internet Information Server (IIS) versions 1.0 and 2.0, if you have write permissions you can overwrite an existing file with the FTP RNTO command. NOTE: This issue will also occur on the Microsoft FTP Server Service in Windows NT version 3.1 through version 3.51. WORKAROUND ========== Create an automated process to copy existing FTP upload files to a separate directory that is not available to the FTP client. This would eliminate the overwriting of existing files through the FTP clients' use of the FTP RNTO command. STATUS ====== Microsoft has confirmed this to be a problem in Microsoft Internet Information Server.
