PDCe不接受外部时间源

Question

我注意到我们的PDCe已经晚了1:20分钟，当然，网络中的其他设备也是如此。我正试图与外部时间源同步，但进展不太顺利。

它是一个虚拟Windows 2008 R2之上的XenServer 6.0.0。主机使用ptbtime1.ptb.de和ptbtime2.ptb.de作为NTP服务器，时间是正确的。PDCe (理论上)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 (我也尝试了ptbtime1.ptb.de,0x1 ptbtime2.ptb.de,0x1而没有结果)，但是当我尝试PowerShell时

PS C:\>w32tm /query /peers
Number peers: 1

Peer:
Status: Pending
Time Remaining: 94.6710000s
Mode: 0 (Reserved)
Stratum: 0 (not specified)
Peer polling interval: 0 (not specified)
Host polling interval: 0 (not specified)

和

我还尝试将HKLM\SYSTEM\CurrentControlSet\services\W32Time\Config\AnnounceFlags从A设置为5，并通过cmdlet再次设置NTP服务器：

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不与外部NTP服务器同步。我不知道XenServer在这个问题上是否扮演了某种角色。在任何情况下，客人的时间与主人的时间不一样。

Answer 1

Type: NT5DS (directive) -告诉我，PDCe与域层次结构同步，而不是与外部时间源同步。

您应该确保您的域连接机器(包括域控制器)都不是与XenServer主机同步的时间。如果在来宾上启用了时间同步集成服务/工具，并与主机同步时间，则应该禁用它。PDCe只应与外部时间源同步，所有其他域客户端都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
