Creating a cluster without Domain Admin permissions

If you’ve ever watched a presentation when someone sets up a cluster you’ve probably noticed that it goes pretty smoothly. The reason for this is because the account which the presenter uses is a domain administrator.

But what about the real world?

In the real world unless you are a systems administrator you probably won’t be a Domain Admin when creating your cluster. There’s a couple of ways to get the cluster setup.

The first way is to be created the permission to create objects within the domain. This is the easiest option. If this isn’t an option then you have the second option available to you.

Pre-staging the objects is option #2. This option requires that a member of the systems administration team create the computer objects for the cluster (and any clustered resources like Availability Groups and Failover Clustered Instances). You also need to have the Domain Admin disable the accounts. This step is critical because if the computer accounts are enabled the Failover Cluster Manager won’t be able to use the computer account, and neither with the cluster when it comes to creating the computer objects for the FCI and/or the AGs.

You’ll also need to configure the computer objects for the actual cluster to be managed by the user who is configuring the cluster. For the other computer accounts (for the FCIs and the AGs) you need to setup the computer account for the cluster to be able to manage these other computer accounts.

    No, you don't assigned IP addresses in AD. You'll need the IPs to create the cluster, but you don't need them to create the accounts.
