Reset Alarms in vSphere 4.1

I had an alarm trigger recently on a Windows 2000 VM I have in a vSphere 4.1 Cluster, the CPU spike was only temporary and I could see that the actual cpu usage had returned to normal but the alarm was still showing in Vcenter and I could not clear the alarm.

This can be done simply by finding the parent for the alarm and then disabling and re enabling the alarm, it looks like a possible bug in vSphere so this is a quick work around that does not have any effect on the live service.

Thanks to http://www.virtualizetips.com/2010/04/how-to-clear-alarms-in-vsphere-vcenter-4/ for the information.
