エラー: DNS に接続してドメイン コントローラを検出できませんでした
環境
- ONTAP 9
- CIFS/SMB
- Microsoft Active Directory (AD)
- Microsoft Active Directory ドメイン コントローラ(DC)
問題
- 特定の操作では、ONTAPがActive Directoryのドメイン コントローラに接続する必要があります。
- AD DCに接続するための前提条件として、ONTAPは既知のすべてのAD DCについてDNSサーバーに問い合わせます。
- ONTAPがDNSサーバーに接続できない場合、操作は失敗し、ONTAPは次のログを記録します:
