I originally had trouble and pinned it down to a combination of Microsoft crapness and bad ftp client. Ended up using LeechFTP and forcing the machine I update my empeg from to accept an entire subnet as fully trusted (I know, a heinous crime for a security professional, but then I have it all physically separated from everything else so the risk is nonexistant)

Things just worked then:-)
