How do I kill a hung task?

I have looked through these forums for this and so far have been unsuccessful in my search, so I will ask...please forgive if this is a dupe question....

I have copied over a template from another ESX 3 vm farm and deployed a Virtual Machine from the template. When I powered on the VM, the "Power On Virtual Machine" task is hung at "In Progress". I cannot cancel the task. Is there a way to KILL the process without rebooting the ESX server?
