Bug? If so, who 'owns' bug?

Weird problem.

If I upload larger files (40+ mb) to our company ftp site, I almost always (80% or better) get a corrupted file. The only way I can check the validity of the file is to download it and then do a binary compare.

I'm pretty sure the errors happen in the upload because the downloaded files are always the 'same' (if I download a file 2-3 times, it will always compare fine with the other downloads).

Typically there are only 4-10 bytes different, almost always near the end of the file (these are all 'zipped files, by the way); thus the reason why larger files fail more often, I suppose.

I have tried WS_FTP, IE-FTP and FlashFXP; all give similar errors.

I use WinZip v10.0 (latest build), and FlashFXP v3.4.0.

I have unloaded my virus scanner (Trend SMB), and all other background programs I can find.

I talked to our host techies, and they (and the winzip people) say it has to be in the file transfer software but I ain't so sure. I'm kinda pointing my finger at our host ISP but I really don't know how to go about 'proving' it.

Anyone have a clue about what's going on?

Thanks.

do you have this corruption problem with that one specific site? try to upload these files elsewhere and see if the problem still exist.
what firewall/router are you using?
