This command says to configure the time service to use a manual list of peers NTP servers , to use a manual source that we just gave it , to mark itself as "reliable", meaning that it can serve time to others, and to inform the service that the configuration has changed. I don't know why one would want to update the config but not use the changes However, when setting up the PDC or fixing time issues, I'd rather wait for the call to complete, and then, i restart the service.

But wait, you say, that "shouldn't" be necessary. And you're not wrong. It "shouldn't". I've been doing this IT thing for over 30 years. I restart the service. Configuring the domain members is even easier. Instead of using a manual list of peers, we don't even tell them to use the DC by name. We use the "domhier" flag to sync to the domain hierarchy. This means that if the PDC changes, all is well. I use the exact same script that I do for a domain controller, including the external sources.

However, you could, instead, point them to your PDC. This is a really annoying gotcha. Independent of all this goodness, Hyper-V will attempt to synchronize the Host and the Guests, blissfully ignoring all the hard work you've just done. In theory, this is a good idea. In practice, I'd rather have my domain members behaving like domain members, and my non-domain members being independent.

In the worst case, the two types of synchronization start fighting with each other and Really Bad Things happen to your Windows time-keeping as the clock changes constantly. I choose to disable it via the registry in almost all of my guest VMs, and I also generally de-select it in the Hyper-V integration settings you know, belt and suspenders. If you choose to allow the Integration components to sync the Guest Time, you must make sure that the Hyper-V server is properly sync'd to the domain or an external source.

I use a script for domain members I'm outnumbered. In fact, I'm been known to put such a script in a GPO as a startup script on the server OU to make reasonably sure that time settings never get messed up again!

But where, oh where, could one ever find such a script? When I learned about computer time in computer networks, Microsoft Windows didn't exist. When I used and configured my first networks with Windows time service, that service wasn't compliant to NTP.

That service was using SNTP at that time. That included the implementations up to Windows and Windows XP and claimed accuracy within 5 minutes. Your URL to Wikipedia is outdated. And be aware that translations may either be more outdate or more up to date. That's sufficient for most use cases. And Microsoft recommended to switch to a higher protocol version if an accuracy of 1 second is required.

I don't run a DC. I'm running a workgroup. I changed the configuration of my Internet access point to use two less used public clocks of a neighbouring university according to the university's recommendation and monitoring.

Registers the Windows Time service to run as a service and adds its default configuration information to the registry. Unregisters the Windows Time service and removes all of its configuration information from the registry. Monitors the Windows Time service. Converts a Windows NT system time measured in 10 -7 -second intervals starting from 0h 1-Jan into a readable format.

Converts an NTP time measured in 2 -second intervals starting from 0h 1-Jan into a readable format. Tells a computer that it should resynchronize its clock as soon as possible, throwing out all accumulated error statistics.

Displays a strip chart of the offset between this computer and another computer. Displays the values associated with a given registry key. Displays the computer's Windows Time service information. Enables or disables the local computer Windows Time service private log. Controls whether this computer is marked as a reliable time server.

A computer is not marked as reliable unless it is also marked as a time server. Not a time server 0x Always time server 0x Automatic time server 0x Always-reliable time server 0x Automatic reliable time server The default value for domain members is Controls whether or not the chaining mechanism is disabled.

If chaining is disabled set to 0 , a read-only domain controller RODC can synchronize with any domain controller, but hosts that do not have their passwords cached on the RODC will not be able to synchronize with the RODC. Specifies the maximum amount of time that an entry can remain in the chaining table before the entry is considered to be expired. Expired entries may be removed when the next request or response is processed. The default value is 16 seconds.

Controls the frequency at which an event that indicates the number of successful and unsuccessful chaining attempts is logged to the System log in Event Viewer. The default is 30 minutes. Controls the maximum number of entries that are allowed in the chaining table. If the chaining table is full and no expired entries can be removed, any incoming requests are discarded.

The default value is entries. Controls the maximum number of entries that are allowed in the chaining table for a particular host. The default value is 4 entries. Specifies the smallest local clock adjustments that may be logged to the W32time service event log on the target computer. The default value is parts per million - PPM. Indicates the maximum number of seconds a system clock can nominally hold its accuracy without synchronizing with a time source.

If this period of time passes without W32time obtaining new samples from any of its input providers, W32time initiates a rediscovery of time sources. Default: 7, seconds. Controls which events that the time service logs.

Time jump 0x2. Source change The default value on domain members is 2. The default value on stand-alone clients and servers is 2. Controls the rate at which the clock is corrected. If this value is too small, the clock is unstable and overcorrects. If the value is too large, the clock takes a long time to synchronize. The default value on domain members is 4. The default value on stand-alone clients and servers is 4. Controls the period of time for which spike detection is disabled in order to bring the local clock into synchronization quickly.

Specifies that a time offset greater than or equal to this value in 10 -7 seconds is considered a spike. Maintained by W32Time. Controls the dispersion in seconds that you must assume when the only time source is the built-in CMOS clock.

Specifies the maximum offset in seconds for which W32Time attempts to adjust the computer clock by using the clock rate. Specifies the largest negative time correction, in seconds, that the service makes. Specifies the largest interval, in log2 seconds, allowed for the system polling interval. Specifies the largest positive time correction in seconds that the service makes.

Specifies the smallest interval, in log base 2 seconds, allowed for the system polling interval. Controls the rate at which the phase error is corrected.

Controls the decision to increase or decrease the poll interval for the system. Controls whether or not the DC will respond to time sync requests that use older authentication protocols. Specifies the amount of time that a suspicious offset must persist before it is accepted as correct in seconds.

An unsigned integer that indicates the time jump audit threshold, in seconds. Specifies the number of clock ticks between phase correction adjustments. Value of 1 indicates that W32Time uses multiple SSL timestamps to seed a clock that is grossly inaccurate. Indicates that non-standard mode combinations are allowed in synchronization between peers. The default value for domain members is 1. Specifies a space-delimited list of peers from which a computer obtains time stamps, consisting of one or more DNS names or IP addresses per line.

Computers connected to a domain must synchronize with a more reliable time source, such as the official U. The default value on stand-alone clients and servers is time. Indicates which peers to accept synchronization from: NoSync. The time service does not synchronize with other sources. The time service synchronizes from the servers specified in the NtpServer.

The time service synchronizes from the domain hierarchy. The time service uses all the available synchronization mechanisms. The default value on domain members is NT5DS. The default value on stand-alone clients and servers is NTP.

The default value for stand-alone clients and servers is 0x Determines whether the service chooses synchronization partners outside the domain of the computer.

The default value for domain members is 2. The default value for stand-alone clients and servers is 2. Specifies the location of the DLL for the time provider. Indicates if the NtpClient provider is enabled in the current Time Service. Specifies the events logged by the Windows Time service. Specifies the large sample skew for logging, in seconds.

Specifies the maximum number of times to double the wait interval when repeated attempts to locate a peer to synchronize with fail.
