Recently i got this error when trying to enable Cluster Aware Updating in Server 2012, i got this error:
“Unable to create the CAU clustered role because a Network Name resource could not be created. This can occur if a computer account (virtual computer object) for the role could not be created in the domain. Check the event log for more information. If the cluster name account does not have permissions to create the object, you can pre-stage a computer account in Active Directory. Then, use the Add-CauClusterRole Windows PowerShell cmdlet with the VirtualComputerObjectName parameter to create the CAU clustered role. For more information about pre-staging computer accounts, see http://go.microsoft.com/fwlink/p/?LinkId=237624.”
to fix this open Active Directory Users and Computers, go to view and select Advanced Features. Navigate to the OU where your Cluster object will be created and right-click on the OU and choose properties., go to the Security tab. Add your Hyper-V cluster computer object, then choose Advanced. From there select your Hyper-V cluster object and choose Edit. Navigate down to “Create Computer objects” and choose check the check box.
Click Apply and Ok, then try enabling CAU again!
Note: By default the new CAU object will be created where the cluster object is.
