IIS FTP RNTO Overwrites Existing Files

Last reviewed: January 21, 1998
Article ID: Q161067

The information in this article applies to:

Microsoft Internet Information Server versions 1.0 and 2.0

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 overwritting 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 versions 1.0 and 2.0. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
