I've got a bog standard NT4 Server with a small registry, but that is holding lots of frequently accessed data. Ghost images, archives etc. amounting to around 70GB. The NIC is 100MB, it's patched to a dedicated 100MB port on a switch etc and is running at full duplex. However, access to the server (when ghosting, attaching etc.) has gone extremely slow. The server has been rebooted, latest drivers for the NIC have been applied along with the latest service pack. I want to run perfmon because even At the server it's slow. Does anybody know what counters would be best to monitor to check to see what is causing this sudden slowdown?
