Thanks for all the great suggestions everyone. Now that I'm back from<br>
holiday I will monitor registers 0x300 and 0x310 per the suggestions.<br>
<br>

<br>
The drives we are using are Lenze i700 drives.<br>
<br>
I will also try changing the network interface. Currently the network interface giving a problem is reported as a<br>
Intel 82579LM which is just a PHY, so I assume the controller is in the chipset.<br>
<br>
I will try using the additional port on my PC which has an Intel 82574L and see if I have better luck.<br>
<br>
I will keep you posted.<br>
