Windows 7 计算机无法同步时间

我按照此处的说明将我的 Windows Server 2008 机箱配置为权威时间服务器：http://support.microsoft.com/kb/816042

端口 123 对服务器上的传入和传出连接开放。

但是，域中的其他计算机（均运行 Windows 7）将不会与其同步时间。

我从各种 w32tm 命令（在 Windows 7 机器上运行）获得以下输出：

C:\Windows\system33>w32tm /config /syncfromflags:domhier /update
The command completed successfully.

C:\Windows\system32>net stop w32time
The Windows Time service is stopping.
The Windows Time service was stopped successfully.

C:\Windows\system32>net start w32time
The Windows Time service is starting.
The Windows Time service was started successfully.

C:\Windows\system32>w32tm /query /source

C:\Windows\system32>w32tm /resync /rediscover

The computer did not resync because no time data was available.

我的事件日志中还出现以下错误：

NtpClient was unable to set a domain peer to use as a time source because of discovery error. NtpClient will try again in 3473457 minutes and double the reattempt interval thereafter. The error was: The entry is not found. (0x800706E1)

我怎样才能解决这个问题？

答案1

请记住，组策略可能会覆盖您的本地注册表设置。

w32tm /query /configuration 在 2008 中查找，我找不到 2003 的等效项。

答案2

在您的服务器上，您究竟是如何输入对等服务器的（引用的 Microsoft KB 文章中的步骤 4c）？如果您只是输入单词同侪正如 KB 中所述，这肯定不行。条目应该是这样的：us.pool.ntp.org,0x1 time.windows.com,0x1 some.other.time.server,0x1

您可以使用命令“net time /querysntp”验证这些设置

如果服务器无法从上游对等点获取可用的时间戳，它将不会向您的客户端宣传自己是权威的，并且客户端可能无法与其同步。我发现 time.windows.com 经常无法向我的服务器提供可用的时间戳；因此我不使用它。
