DNS config for domain server

This is the error I get, can anyone help me with the entry i need to put in the DNS? What is the entry and where do I put it?

DNS was successfully queried for the service location (SRV) resource record used to locate a domain controller for domain ORD.nextiva:

The query was for the SRV record for _ldap._tcp.dc._msdcs.ORD.nextiva

The following domain controllers were identified by the query:

ord_vid_ms_01.ord.nextiva

Common causes of this error include:

– Host (A) records that map the name of the domain controller to its IP addresses are missing or contain incorrect addresses.
