Having an ongoing issue which am edging closer to solving.
If I copy a 1.3gb file from either a windows XP or Windows 7 device to our NAS device running windows server 2003 appliance edition - it copys around 900mb within 45-60 seconds, then the transfer rate slows down to as low as 9mbps and it then takes a total of 7 - 9 minutes to complete the transfer.

Doing the same copy from XP to a Windows 2008 server takes 70 seconds, and from Win7 to Server 2008 takes 25 seconds.

The other comparison is from XP or Win7 to Windows Server 2003 web edition - also takes around 35 seconds.

However - a 650mb file copies from XP or Win7 to any server in under a minute, no issues at all.

The entire network has been replaced, new HP gigabit switches, CAT 6 cables, and all the network cards on the devices have had the latest drivers.

Hope someone can help point me in the right direction.
