FTP conn issue between 2 servers.

Am trying to backup some files using HandyBackup between two win2003 servers
via the internet.

I get a "Socket error = #10060" when I try to FTP from a remote 2003 server
to a local 2003 server .
The local 2003 server works fine all the time from other remote XP pro
clients using CuteFTP.

I tried PASV and non-PASV modes from the remote server but still cannot
connect..

When I restart the RAS at both servers, it works for a short time, but later
fails..

Also tried using Serv-U FTP server at the local server- same thing..

Both servers are using DHCP and RAS w/2 NIC's.

Anyone have any suggestions as to is going on?

Thanks

Jim
