無法聯繫域的 Active Directory 域控制器 ad dc

我在 Windows Server 2019 中創建了一個域，但客戶端無法連接。兩台電腦都通過 VPN 連接。

server  have vpn ip **10.8.0.6**
client  have vpn ip **10.8.0.7**

我得到了這個錯誤

將您的客戶端（和伺服器）DNS 伺服器（TCP/IP 設置）指向正確的伺服器。DNS 是 ActiveDirectory 中一切的基礎，您的客戶端使用“1.1.1.1”作為 DNS，這是一個 cloudflare DNS-Server。我懷疑 cloudflare 是否有您的私有 AD DNS 區域的副本。

所有 AD 客戶端（包括 AD DC）都必須具有有效的 DNS 基礎設施，在您的情況下適用於 zone m1.local。
