Could not connect to server

[jimmytop]

Have tried SmartFTP and FileZilla and can't connect to home.comcast.net ftp server.... Pretty sure its a problem on my side. I disabled Kaspersky Internet Security but that doesn't help. It's the only software firewall running. Tried some things in my Router setup but nothing worked there either.

I get the following:
Resolving IP-Address for home.comcast.net
Status: Connecting to 216.87.188.20:21...
Error: Could not connect to server
Status: Waiting to retry...

I double and triple checked user name and password. What could be causing this?

fyi smartftp gives this:
[20:06:19] Resolving host name "home.comcast.net"
[20:06:19] Connecting to 216.87.188.20 Port: 21
[20:06:20] No connection could be made because the target machine actively refused it.
[20:06:20] Cannot login waiting to retry (30s)...

Also, I am able to login fine to this user account on the comcast.net web site, and have web access to email, etc so I know the username and password are ok... Personal Web Page is enabled, and I can use comcast's crappy web based site editor to do stuff. But FTP no go.

There doesn't appear to be a server running under the given address.
