If FTP doesn't work but HTTP does work, it's obviously an upper-layer problem, as someone else mentioned. One possibility is an access list somewhere, a firewall, personal firewalls.
Are the affected users on different types of computers, operating systems, applications? That would be my guess. Or could those users not know to use active versus passive FTP (or the other way around, depending on your set up) while the other users do know to use it? FTP is infamous for having problems with firewalls, proxies, NAT gateways, etc. because of the way active and passive FTP work, and other issues, including the inclusion of an IP address in some of the FTP commands.
