File corruption while transferring via Intranet...

We have seen some file corruption when transferring large files from within our Intranet. It seems that the speed at which the files are being transferred are causing corruption within the file.

The same large files, when transferred from outside our Intranet, albeit at much slower speeds, seem just fine.

Is it the speed of transfer that is the problem? Should I throttle down the speed?

Any ideas?

There are no know problem related to high transfer speeds. Most likely something else in your network is causing the problems.

Here are some possible reasons I can think of:
- outdated or broken drivers (especially ide and network card drivers)
- broken hardware (network card, harddisk, switches, even cables)
- virus scanners
- viruses, trojans, spyware
- firewalls
- routers

All the above mentioned possible causes are very sound.

But you might want to check the cable type first. If files ARE being transferred and fast, but there is a constant need for resending tcp packets because of file corruption, then it is fairly safe to assume something is changing the contents of the packets while they are being send through te cables. Everything magnetic and unshielded that is.
Shielded cables can fix that. You are probably not using category 5 for 100MBit, or not category 5e or even category 6 for 1000MBit.
If there are no magnetic interference sources nearby, you can use unshielded cables, but should still mind the speed limit the different cable types are designed for.
