Failover Cluster - Error 0x800703eb when creating File Server role

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:

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