This is being on a Win 2008r2 host, running as DC (hyperV enabled). On attempts to add the HOST this process fails on setp 1.2 [Install Virtual Machine Manager Agent] with the below error.
The agent & SCVMMService services are running.
Error (2912)
An internal error has occurred trying to contact an agent on the WinServ.ServDomain.com server: NO_PARAM: NO_PARAM. Cannot perform this operation on built-in accounts (0x8007055B)
Recommended Action
Ensure the agent is installed and running. Ensure the WS-Management service is installed and running, then restart the agent.
