I was wondering if anybody could help me solve this very annoying problem. I have two windows xp pro machines both on sp1a. Whenever i copy files over the network one of the computers will use very little cpu usage while the files are copying, but the other computers cpu usage will jump to 100% usage and the copying of the files will go at about 20 Mbits/s as apposed to 100mbits/s as it should. The network utilization in the windows taskmanager is also only at 10 - 15%.
The motherboard is a gigabyte GA-7N400 Pro2. Link here
The problem occurs when using the onboard 10/100/1000 lan (i then completely disable the onboard lan by uninstalling it from device manager and then disabling it in the bios) and when using a dlink 530TX 10/100 network card link here
Anybody any ideas because it is very frustrating when trying to copy large files over the network and it taking 5 or 6 minutes to copy a 700mb file when it should be nowhere near that long.
