Can't remove mystery folders

Posted on 2004-11-26

We're running Win2k Server with IIS.

In some of the web sites it appears we have been tagged. There are some mystery folders (non system, non user) that have appeared with such names as "_tagged by chris" or similar. Some of the folders are unnamed, and appear to be empty.

There are a couple of problems here.

1) We block all ports except 21,22,110,80,443. I think they're being created via the FTP port as when we block this port no new folders appear, and they only appear in the root directory of the FTP folder. Problem is that we need the FTP port open. We change the password frequently, but no luck. Any suggestions?

2) Folders can't be deleted from Windows Explorer or from a command prompt. The OS reports "Cannot delete file: cannot read from source file or disk". Not sure if it's creating any further problems or if it's just simply annoying. I'd like these folders gone.

Thanks for your help. Any suggestions would be appreciated.

    You mention that you need port 21 open.  Is this an internal reason, i.e. for staff, or an external one, i.e. for customers?  It is perfectly possible to change the FTP port to something less obvious.  You could also use a secure ftp server such as SafeTP (

    These solutions only work if you can dictate to the users what ports and clients they use!

    Thanks to both of you for your input. I'll be cleaning up the FTP folder and changing the port based on your suggestions. Thanks again.
