wan

We have two scanners in our branch office which upload images to the head office via FTP. In the last week, both scanners have started delivering a lot of corrupted images.

I suspect that the problem may be with the WAN link, and that TCP might not be detecting/correcting all errors. Is there any software for Windows that allows me to test the integrity of the connection by sending packets with an embedded CRC?
