Failover Cluster Manager failed while managing one or more clusters, the error was unable to determine if the computer exists in the domain


A failover cluster is a group of independent computers that work together to increase the availability and scalability of clustered roles (formerly called clustered applications and services). The clustered servers (called nodes) are connected by physical cables and by software. If one or more of the cluster nodes fail, other nodes begin to provide service (a process known as failover). In addition, the clustered roles are proactively monitored to verify that they are working properly. If they are not working, they are restarted or moved to another node. Failover clusters also provide Cluster Shared Volume (CSV) functionality that provides a consistent, distributed namespace that clustered roles can use to access shared storage from all nodes. With the Failover Clustering feature, users experience a minimum of disruptions in service. and the associated offered by Fiber Channel SAN can not be achieved by iSCSI.

Failover Clustering has many practical applications, including:
- Highly available or continuously available file share storage for applications such as Microsoft SQL Server and Hyper-V virtual machines.
- Highly available clustered roles that run on physical servers or on virtual machines that are installed on servers running Hype.

Reason for the Cluster Registration error: As you can see from the images below, the following error was prompted “Failover Cluster Manager failed while managing one or more clusters, the error was unable to determine if the computer exists in the domain”. This is because I was logged in locally without having the necessary privileges to create the Failover Cluster in Active Directory.
– I was configuring the Hyper-V Cluster using a Local Admin Account. This account didn’t have the right privileges to create a computer account in the organizational unit.

Solution: Your user account must have the correct privileges to create a computer account in the Domain where the nodes reside or the computer account must be pre-staged in that location.
– Login with your Domain account and the error will be eliminated.


Continue with your Cluster creation. Enter the Cluster Name and IP address as shown below. See this article on how to create a Failover Cluster” on Hyper-V.


As you can see, the Cluster note was created successfully in AD and you can continue with the rest configuration steps as shown below.

Like I said before, the node was successfully created in AD.
