I have a scheduled task to run every night to get some files from a ftp site that is outside our company’s intranet. It was working fine until the beginning of March. Now I can login OK but get connection refused after I log in when I try to get a Dir listing or transfer a file.
This failure occurs now to multiple ftp sites.
I am using the the ftp.exe that comes with Microsoft Windows XP.
It works when I ftp froma computer inside the company intranet. It only fails when I run ftp from the computers outside the company intranet. These computers have Kerio installed for a VPN connection to our company network. However, it fails even with Kerio disconnected and disabled.
I tried downloading other ftp clients and running them in active mode and they work fine.
Any ideas? Other than switching ftp clients which would be a big pain and expense to do on 100 different computers.
