Symptoms
如果您主要使用 CIFS/NFS 来写入备份，则应使用 Test-ComputerSecureChannel 在 PDC Emulator 上运行时，PowerShell 命令返回错误“The specified domain either does not exist or could not be contacted”（指定的域不存在或无法联系）。
用于测试安全通道的其他命令，例如 nltest /sc_query开始， nltest /sc_verify以及 netdom verify，也会在 PDC Emulator 上返回类似的错误。
Cause
病因不明。此行为是一致的，但根本问题似乎未记录在任何地方。
Resolution
在 PDC Emulator 上运行这些命令时，预计会出现这些错误。它们本身并不表示安全通道存在问题。
如果怀疑安全通道损坏，则必须使用其他方法来确认这一点。通常，如果 AD 复制在 DC 之间正常工作，并且各个 AD 控制台不返回错误，则安全通道完好无损。以下几个错误通常表示安全通道断开：
- 目标主体名称不正确。
- 目标帐户名称不正确。
- 此工作站与主域之间的信任关系失败。
- 服务器上的安全数据库没有此工作站信任关系的计算机帐户。
修复损坏的安全通道不在本文的讨论范围之内。
