Summary
The documentation is heavily focused on Windows-based Active Directory and DNS disaster recovery, with all examples, tools, and troubleshooting steps referencing Windows Server, Windows command-line tools (e.g., dcdiag, nltest, dnscmd), Windows registry edits, and Windows-specific concepts (FSMO, SYSVOL, DFSR, FRS). There are no examples or guidance for Linux-based domain controllers (e.g., Samba AD DC) or DNS servers, nor are cross-platform considerations addressed. The documentation assumes the use of Windows Server throughout.
Recommendations
  • Add sections or notes for environments using Samba Active Directory Domain Controllers on Linux, including replication and failover considerations.
  • Provide equivalent Linux-based DNS server disaster recovery steps (e.g., BIND, dnsmasq), including example commands for zone backup and restoration.
  • Include Linux command-line equivalents for key operations (e.g., checking DNS/AD health, updating DNS records) where possible.
  • Clarify early in the document that the guidance is specific to Windows Server AD/DNS, and provide links or references for Linux-based alternatives.
  • If Azure Site Recovery supports Linux-based AD/DNS, explicitly document the supported scenarios and any differences in procedure.
