FTP

Hi;

I have a PII 300mgz, 256mg RAM ftp server(W2K). When clients log on and download files, the connection drops and gives then this error message "125 Data connection already open; Transfer starting.426 Connection closed; transfer aborted" I doubled the connection time out from 900sec to 1800sec. What do I need to do to solve this problem. Do you think the problem will be taken care of if I use better and faster machine? Is there any hardware requirment for FTP server?
