windows 2003 server slow access
I have a Windows 2003 server which has RAID 5 storage which I have set up in the disk management of the motherboard and hard drives use sata 3 which is meant to be 6Gb per second. It also has 8GB RAM and a 6 core 3.3MHz AMD processor with 2 1Gb ethernet PCI cards, which is connected to a 1Gb switch. We run and application from the server which works fine on most workstations but 2 are causing time out problems. They are in totally different parts of the factory the are both on 100Mb ethernet and I think they are connected to the same switch as the server.
I am totally stuck on what could be causing the problem. Do you have to do anything to enable the sata to work at 6Gb?
