in my opinion i would check two things:

* check any routers/switches hubs for collisions, if so then check cables 
etc... and maybe change network cards to stop them (some makes are just crap 
via?)

* if no collisions then look at port activity or at the back of the machine, 
the activity light should flickering damn fast when transferring data if 
everything is working ok. if not change the network cards used.

I have had a similar problems using FTP and samba on a lan. The causes were:

*via onboard network cards are crap -> replaced with 3com and the problem went 
away
* old d-link hub was knackered -> replaced and the problem went away.

Also check the duplex states of the cards, one could be in full duplex and the 
other in half duplex.
