Hi Brian, try this: First that all make a Backup of you ISA server configuration, the go to extensions in the ISA console, and disable the FTP Filter, then you must create a protocol rule to FTP, try this configuration, FTP Filters send the reques of FTP clients to NAT server, and open ports on demand (FTP Filters its more secure). In some cases you must disable(Restar ISA services) and Enable(Restart ISA Services)the FTP Filter. -----Mensaje original----- De: Rogers, Brian [mailto:RogersB@xxxxxxxxxxxxxx] Enviado el: Vie 03/05/2002 02:41 p.m. Para: [ISAserver.org Discussion List] CC: Asunto: [isalist] Published FTP site doesnt allow "LS" command http://www.ISAserver.org Ok...what gives We have published a dozen or so FTP sites from an internal IIS box through the ISA server. Until yesterday they were all working fine. Now two of them allow users to log on, however no longer allow the LS command to work. Upon executing LS after logging in freezes up the FTP session and eventually it times out. Anyone seen anything like this? Brian W.
