I've loaded the server and IIS management using the "Turn Windows Features on and off" in the control panel.Afterwards, attempting to connect returns " unknown error number " from a media center PC and "connection refused" from a Vista Ultimate PC.Disabling Firewall and security software has had no effect.A port scan from a remote host shows port 21 is not available and locally netstatindicates the port is not active/listening or otherwise.Uninstalling and reinstalling the IIS components and server has had no effect.Any ideas?

Hi, Based on my research, I would like to share the following with you: Configuring FTP Firewall Settings If the computer is connecting via a router, please also check the routers settings to ensure that the port 21 is not be blocked. Considering this issue is related to IIS and we have specific support for this, it is recommended that you go to our IIS Forum for help: IIS Forum Thank you for your understanding and cooperation. Hope the issue can be resolved soon!Nicholas Li - MSFT
