DNS_ERROR_LOAD_ZONESCOPE_FAILED

DNS_ERROR_LOAD_ZONESCOPE_FAILED means the DNS server could not load data for a named zone scope. The problem can involve the scope data, file access, or an inconsistent configuration between the zone and the scope.

What to check

  • Review the DNS Server event log at service startup or the time the scope was loaded.
  • Verify the parent zone is healthy before treating the scope as an isolated failure.
  • Compare the configured scope list with the files or directory-backed zone data that should provide it.
Get-DnsServerZoneScope -ZoneName "example.com"
Get-DnsServerQueryResolutionPolicy -ZoneName "example.com"
