Cluster Network Name failing to come online

[Balaji]

I am installing a server cluster. The cluster network name is failing
to come online with the following error.


Cluster resource 'Cluster Name' failed to go online because its
associated computer account (INGBTCPIC5XX093) exists in Active
Directory and the Kerberos authentication is not enabled for the
resource. Client applications that are using Kerberos based
authentication (either directly or through the Negotiate security
package) will fail to authenticate when contacting a service by this
network name.

To bring the resource online, either enable Kerberos authentication or
delete the computer account.

Any help to resolve the issue will be highly appreciated.

So, did you delete the computer account?

No, the network name is registered in the DNS.

The error, to me, seems to be stating that the account exists in AD but the
Network Name is not enabled to use the account. So, back to my statement,
did you try to delete the computer account in AD? After all, that is what
the error is pointing out as a possible solution, or to enable Kerberos
authentication for the Network Name resource.

Sorry for not responding to the conversation.

I am restarting this conversation as I am facing the same issue again.
Yes I did delete the computer account from the AD.

If you delete the computer account does it also delete the A_Record
associated with it? Try deleting that also.

When SQL Server is installed on a cluster, kerberous authenication is
disabled by default.

If kerberous authenication needs to be enabled for the SQL Server
network resource, then the cluster service account needs to have
permissions to update the active directory. If the cluster service
account doesn't have the required permission then the SQL Server
network name fails to come online.

If you don't want to use the kerberous authenication and the cluster
service account doesn't have permission to update the active directory
then the workaround is delete the computer object from the AD and
bring the SQL Server Network Name.
