So this guys VPN's in from the field and FTP's a bunch of files to a shared folder..sometimes it works sometimes it doesnt. Originally we were using windows ftp server, I tried switching to ServU ftp and the same thing. If I just connect to the box from the office it works fine, but VPN'ing in it gets messed up. Now I think the NIC card on the box is going cause there are checksum errors but could that cause this problem? Not sure what else to try at this point. Cliffs: FTP works fine locally, when VPN'ing in it only works half the time. What should I try next?
