Error while creating Windows 2016 Cluster at "Find a suitable Domain Controller"

Description:

You want to create Windows 2016 cluster on Windows 2012 R2 Domain. You run the Wizard, however encountered error and the cluster cannot be created. 

During investigation, you saw several error message such as:
"Check whether the computer object "clustername" for node "hostnameFQDN" exists in the domain. More data is available".

At event viewer (after enabling Debug Log) you could see:
"Failed to find suitable DC. Error 234"
"Searching for object "clustername" on first choice DC failed. Error 234"
"Couldn't resolve RPC binding to cluster, Status = 1753"

You then try to run the Cluster Validation wizard but everything seems to pass. You validated that the required AD permission for the User Account creating the Cluster are already meet. You also verify the Group Policy setting for "Deny Access to this computer from the Network" is correct. You check the network port requirement and verify all the necessary port are open.

Resolution:

First, verified the DNS record in your DNS Server. Especially the record for all of your Domain Controllers. Make sure the Active Directory required Zones has the correct NS records, CNAME records, A Records, and also SRV DNS records. Remove the stale records for old or unknown broken Domain Controllers.

Second, check the Application partition (DomainDnsZone and ForestDnsZone) in your Active Directory. Use ADSIedit to connect to the application partition and try to browse the content. If you encountered error, you may need to delete the application partition using NTDSUtil.
You should be able to create the Windows Cluster afterwards.
