1. Why is Shared Backup Storage Necessary for the RMAD Server?
To confirm why the RMAD server requires a shared folder for backup storage. In some environments security configuration inherently disallows shared folders.
2. Why is the DNS Client Windows Service Required?
To understand why the DNS Client service is necessary. In online recovery and similar operations fail if the DNS Client service is stopped. In some environments security configuration also inherently disallows the DNS Client by default.
To provide better explanation and clarification on above questions, why those are require by RMAD:
1. Why is Shared Backup Storage Necessary for the RMAD Server?
Quest RMAD requires a shared backup folder because, during forest recovery, domain controllers boot into DSRM mode and must connect to a network-accessible location to retrieve backup data and recovery configuration files. This access cannot rely on Active Directory authentication, so a secure SMB share is used as the most reliable method to deliver recovery data in an offline state. The share can be secured with strict access controls, firewall rules, and SMB encryption to meet high-security standards.
2. Why is the DNS Client Windows Service Required?
The DNS Client (Dnscache) service is required by Quest RMAD to perform essential hostname resolution during online Active Directory object recovery, agent deployment, and forest recovery tasks. Without it, the system cannot resolve domain controllers or the RMAD server name, which causes recovery workflows to fail. While disabling the DNS Client service may align with certain security hardening practices, it breaks Windows' standard name resolution APIs. For RMAD to function correctly, this service must be enabled and running on both the RMAD server and the domain controllers involved in recovery.
