You may want to try lowering your idle timeout on files as well. IIS4
defaults to 900 seconds (15 minutes) so this is way too long if your sites
are busy, and accessed regularly.

Subject: Self deleting files with IIS4 and War FTP daemon
>We've got a very very strange problem with one of our NT servers. We are
>running IIS4 and have around 50 or so web sites on it. We use War FTP
>to let the users upload their files.
>Recently (as of the past couple of days) people have been reporting that
>they are unable to overwrite existing files that are on the server. Their
>FTP clients are giving them access denied messages. When we looked at the
>files via Explorer (logged in as Admin on the NT Server) we were unable to
>open, rename, copy, move or delete the files. Each one gave an Access
>error message. What's more, Disk Administrator showed no files as being
>locked or in use and Event Viewer showed nothing strange.
>We shut down the server and rebooted it. The files vanished. They'd
>literally be deleted from the hard drive with no intervention on our part.
>We played for hours and hours.. the end result being this.. if IIS has a
>file locked open (i.e. someone had viewed the web page and the browser was
>still on that site) and at the same time, the author uploaded a replacement
>file, it trashed it. It's as if IIS has a lock on the directory and the FTP
>software can't override or use it.
>When the web browser was closed down and we knew there was nothing
>that site via IIS, the ftp worked perfectly.
>Does anyone have ANY ideas at all as to what the hell is going on here? I'm
