I'm running a FTP server on my Windows Server 2008 R2, using Filezilla Server to manage accounts. I've had zero problems using it as a client, and most of our clients have no issues either. But it seems like our more "corporate" clients tend to have connectivity problems, where they can't access it at all or can start downloads that get interrupted. I'm guessing this is because of the IT infrastructure of the offices that they are working in, and some sort of firewall issues.
I'm a developer not a sys admin, so I'm at a loss here. I don't know what to tell this client who insists it's been very problematic. Do you have any advise as to what some general issues may be. Thanks,
