我注意到我们的 PDCe 运行时间晚了 1 分 20 秒，当然，网络中的其他设备也一样。我尝试与外部时间源同步，但进展不顺利。
这是基于 XenServer 6.0.0 的虚拟 Windows Server 2008 R2。主机使用 ptbtime1.ptb.de 和 ptbtime2.ptb.de 作为 NTP 服务器，时间正确。PDCe（理论上）具有相同的 NTP 服务器，但时间大约晚了 80 秒。我说“理论上”是因为HKLM\SYSTEM\CurrentControlSet\services\W32Time\Parameters\NtpServer有值ptbtime1.ptb.de ptbtime2.ptb.de（我也试过，ptbtime1.ptb.de,0x1 ptbtime2.ptb.de,0x1但没有结果），但当我在 PowerShell 中尝试时

我还尝试通过 cmdlet 设置HKLM\SYSTEM\CurrentControlSet\services\W32Time\Config\AnnounceFlagsNTP服务器并再次设置A：5
PS C:\> w32tm.exe /config /manualpeerlist:"ptbtime1.ptb.de ptbtime2.ptb.de" /syncfromflags:manual /reliable:YES /update
PS C:\> w32tm /config /update
PS C:\> w32tm /resync
PS C:\> Restart-Service w32time
我不明白为什么服务器无法与外部 NTP 服务器同步。我不知道 XenServer 是否在这个问题中扮演了某种角色。无论如何，客户机中的时间与主机中的时间不一样。

答案1
Type: NT5DS (directive)- 告诉我 PDCe 正在与域层次结构同步，而不是与外部时间源同步。
您应该确保加入域的计算机（包括域控制器在内的所有计算机）未与 XenServer 主机同步时间。如果来宾上启用了与主机同步时间的时间同步集成服务/工具，则应禁用它。PDCe 应仅与外部时间源同步，所有其他域客户端应与域层次结构同步。
在 PDCe 上尝试以下命令：
W32tm /unregister
Net stop w32time
W32tm /register
Net start w32time
w32tm.exe /config /manualpeerlist: "ptbtime1.ptb.de ptbtime2.ptb.de" /syncfromflags:manual /reliable:YES /update
Net stop w32time
Net start w32time
