I have a ftp server (windows 2003) in Arizona with some users created on it. One of my user in California who was using it regularly without any hassles now says that my server does not let him upload files any more. He says that the ftp server connects for a while and then returns with a message that "you do not have permission".
However, if tried from a different location to my ftp server, we are able to log in and upload. I am very confused. We thought it could be a firewall issue and therefore disabled the windows firewall on those systems. Still no luck. Then we thought the ISP must be blocking the ftp protocol. But, when we tried to upload to different ftp servers from those computers, it works!
Can you please advise what could be wrong and how to rectify the situation?
Thanks for your time.
