DC降級失敗
將DC降級為member時發生錯誤,錯誤訊息如下:
作業失敗,因為:
Active Directory 網域服務無法傳輸目錄分割區中的剩餘資料
DC=DomainDNSZones,DC= < DNS domjain name > to Active Directory 網域 Controller
\\ < DNS 用於服務降級的協助程式 DC 名稱>
「目錄服務遺漏必要的設定資訊,無法判斷浮動單一主機作業角色的擁有權。」
建立 fixfsmo.vbs
‘——-fixfsmo.vbs——————

End if
End if
執行
cscript fixfsmo.vbs DC=DomainDnsZones,DC=contoso,DC=com
ldifde -f Infra_DomainDNSZones.ldf -d “CN=Infrastructure,DC=DomainDnsZones,DC=domain,DC=com” -l fSMORoleOwner
執行下列指令確認結果
cat .\Infra_DomainDNSZones.ldf
測試後,仍然有錯誤,參考:Demoting a Domain Controller Error (microsoft.com)
將 DC=DomainDnsZones 改為 DC=ForestDnsZones,再次執行
cscript fixfsmo.vbs DC=ForestDnsZones,DC=contoso,DC=com
ldifde -f Infra_DomainDNSZones.ldf -d “CN=Infrastructure,DC=ForestDnsZones,DC=domain,DC=com” -l fSMORoleOwner
執行下列指令確認結果
cat .\Infra_ForestDNSZones.ldf
再次進行降級程序,順利完成
