I have pretty good networks guys in my team ( no kidding ! ) If these were my Network guys , they would immédiately suspect settings in the ethernet cards . They would most likely find that the speed is being negociated instead of being "hard coded" to 1 GB full duplex or 100 Mb full duplex They would also remove ( set off ) all offload functions( also called optimisation or whatever) from the cards itself because some brands are incompatible with some routers from another brand standing in the path between your client and server . What you are describing is quite often coming from these settings . a trace would show that the stack is regularly being restarted because of some synch loss problems . But I am no network expert .
