Our server that hosts SBS 2011 experienced a hardware failure and has been moved to a 100% identical server chassis. The server is the exact same model (IBM x336) - Same exact specs.
The RAID 1 HDs were moved into the new server and everything went as expected. I needed to reactivate the OS, as it detected a hardware change, and everything is up and running.
Of course, I didn't expect to see what I'm experiencing now with it. It appears that 3 services are in a knock-down drag-out battle to the death on CPU usage.
w3 - IIS
Ever since the change, (Approx 30 hours ago) - CPU usage on the SBS box has been 100% from a mix of those services. Of course, this makes performance of the server itself absolutely horrible.
Nothing was out of the ordinary before the failure. (And on note - the failure was attempting to upgrade RAM in the old chassis). I shut the old server down, and tried to mount the memory, where the old server coul no longer POST after that point (Ebay purchase). - So move everything over to a 100% identical chassis, and it fires up no problem.
Would anybody happen to know why the CPU usage would be as horrible as it is on this server?
