The Host record for the local computer cannot be found in the DNS database
Applies to: Exchange Server 2013
Topic Last Modified: 2013-04-10
Microsoft Exchange Server 2013 Setup can’t continue because the Host (A) record for this computer can’t be found in the Domain Name System (DNS) database.
Exchange 2013 Setup requires that the local computer have a valid HOST (A) record registered with the authoritative DNS database for the domain.
Exchange depends on DNS Host (A) records for the IP Address of its next internal or external destination server.
To resolve this issue:
Verify that the local TCP/IP configuration points to the correct DNS server. For more information, see Configure TCP/IP settings.
Use Nslookup.exe to verify that the Host (A) record exists on the DNS server. For more information, see To verify A resource records exist in DNS.
For information about DNS name resolution, troubleshooting, and Host (A) records, see the following:
