This server is a basic file server that started to run 90-100 CPU. After checking the task manager it is the System process that is doing it.
The CPU does settle down in the evenings when staff go home but the System process is still a bit high but the server is atleast manageable. It runs in the 25-35% spiking in the 70-80 for short bursts.
After extensive testing, changing out hardware EG Raid Controller, NIC, we think have narrowed the issue down to the Network.
We have found out if we disable the NIC or unistall it, the server runs normally. As soon as we install or enable the NIC the System process CPU usage jumps way up.
