A few weeks back, I removed the Hyper-V role from a server that never should've been configured as a HV host in the first place.
NPM still has this server listed and red under the virtualization summary. When trying to go in and uncheck the Hyper-V resource for polling, the option isn't even available to uncheck, so the best I can do for now is to disable Hyper-V polling.
Short of reinstalling the HV role, rebooting, reconfiguring NPM, then removing the role and rebooting the server again, is there some way to remove this poller from the node?
