FTP in internet explorer not working

I’m not able to run FTP in internet explorer anymore. (ftp.dlr-now.com). My clients use it to copy files over.

It doesn’t bring up the username/password combination, just the message about going to 'page/view in explorer). I’m fine getting to it with an ftp program so I know it’s running okay.

Is there something I can change to fix it back?

Jeez, nothing at all? does anyone even look at this board anymore?
