Hi,
I've got a win 2000 and 2003 servers, both with gigabit NICs, both plugges into gigabit ports on my Zyxel switch, but when coopying files between then the "network utilisation" only runs at about 10%.
How do I utilise our full availability?

Just because you are only showing 10% of network utilization does not mean you are not transfering at 1gbs. transfer a 1gig file and time it. Also check both NIC's properties. I find that QoS does sometimes slow things down.

Don't forget that your computer's hard drives might not be fast enough to transport data that quickly across the pipe either.

Well, with Ultra 320 scsi drives, you are typically looking at around 40-80MB/sec transfer rate (the 320 rating is for burstable rates for stuff already in its cache).

So 80MBps is 640Mbps...so ideally you'd be getting about 60% utilization on a gigabit NIC.  However, if you are still using regular frame sizes of 1500MTU and not Jumbo Frames, then the NIC is probably sending the 1500 packet quick enough to "leave it and receive it" physically that you aren't seeing much utilization overall.

Try Jumbo Frames, or even something like this: http://www.ibeast.com/content/tools/band-calc.asp to determine the file size and see what a normal transfer time would be.
