Tool

Domain services for Windows is tightly integrated with DNS. Primary Domain controller typically acts as DNS server for the Domain. Upon adding Domain Controller or Workstation to the domain, DNS zone records for these will be created and updated in “domain.db” file of Forest Root Domain.

This tool validates whether DNS entries for forward lookup and reverse lookup of each domain controller and workstation of the DSfW domain is properly created. This is a health check for DNS to ensure proper functioning of DSfW Domain.

To check the DNS record entry for each domain controller and member server, run the script at command line as:

perl  check-dns.pl

Output of the script states the health of DNS records for each domain controller / member server by listing the records with “OK” / “NOT OK” .
