DNS Error | A new record cannot be created

DNS Error | A new record cannot be created

DNS Error | A new record cannot be created. An alias (CNAME) record cannot be added to this DNS name. The DNS name contains records that are incompatible with the CNAME record.

If you are trying to create a new alias (CNAME) record in Windows DNS server and gets the DNS error “A new record cannot be created. An alias (CNAME) record cannot be added to this DNS name. The DNS name contains records that are incompatible with the CNAME record” then below can be the causes for this

 

This error comes mostly due to conflict between DNS records. so one has to verify that same name shouldn’t be use anywhere in your DNS

  • Host A Record:- There are very high chances that there is an Host A record already created for the same DNS entry for ex:- you are trying to create CNAME record of “www” in abc.com zone that points to www.xyz.com but abc.com zone is already has “www” Host A record that points to any IP address in this case you will encounter with this error. if this is the case then delete the Host A record and then create a alias (CNAME). There is no point to have both records. Sometime register DNS might auto creates a Host A record kindly remove this setting and do the setting accordingly.
  •  Wildcard Domain:- Make sure you don’t have this record created as wildcard (*.abc.com) Host A record or make sure there is no Zone is created of same fqdn in your local DNS or any first hop DNS for non-recursive queries.
