Microsoft® Exchange Server 2007 setup cannot continue because the Host (A) record for this computer cannot be found in the Domain Name System (DNS) database.

Exchange 2007 setup requires that the local computer have a valid HOST (A) record registered with the authoritative DNS database for the domain.

Microsoft 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.

    To verify the local TCP/IP configuration
    1. Review the local TCP/IP configuration. For more information, see "Configure TCP/IP to use DNS" (http://go.microsoft.com/fwlink/?LinkId=68094).

  • 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" (http://go.microsoft.com/fwlink/?LinkId=63001).

For information about DNS name resolution, troubleshooting, and Host (A) records, see the following:
