Having created a new cluster today I received the following error when trying to configure the File Server role: Cannot complete this function. Ox800703eb

The Solution:

I had forgotten to give the Cluster Name Object (CNO) the permissions it requires in Active Directory.

On the OU that contains your cluster Server nodes \ CNO perform the following steps:

  • Right-click the OU -> Properties -> Security -> Advanced
  • Change the object type to ‘Computer’ and select your CNO.
  • Grant it the following permissions: ‘Create Computer Object’ and ‘Read All Properties’
  • Then delete the role from cluster manager and re-add it.
