This is a pretty quick and easy solution for setting that up. Verify your account to enable IT peers to see that you are a professional. I completely agree. There are plenty other external time servers to choose from. Feanor May 8, at UTC. Thanks All! Thanks Alex, for the detailed steps. Your method worked for me on r2. Glad it worked out for you brianm3. Mel was a great help with his earlier post. Also, make sure you open port on your routers in the dmz to accept time protocol from the outside.

Hi, i made some progress, the script can be used from Computer Client like Win10, and he dont need to import Active Directory modules, also dont need to enter config.

I always install NetTime as a service Freeware and easy to isntall. Tim Warner 10 years ago. Hi Allen, Can you please be more specific as to what "isn't right" about my article? Pete 10 years ago. Max 9 years ago. The default value for stand-alone clients and servers is MaxNegPhaseCorrection All versions Specifies the largest negative time correction, in seconds, that the service makes.
If the service determines that a change larger than this is required, it logs an event instead. This value means that the service always corrects the time. The default value for domain controllers is , 48 hrs.
The default value for stand-alone clients and servers is 54, 15 hrs. MaxPollInterval All versions Specifies the largest interval, in log2 seconds, allowed for the system polling interval. Note that while a system must poll according to the scheduled interval, a provider can refuse to produce samples when requested to do so. The default value for domain controllers is MaxPosPhaseCorrection All versions Specifies the largest positive time correction in seconds that the service makes.
MinPollInterval All versions Specifies the smallest interval, in log base 2 seconds, allowed for the system polling interval. Note that while a system does not request samples more frequently than this, a provider can produce samples at times other than the scheduled interval. The default value for domain controllers is 6. PhaseCorrectRate All versions Controls the rate at which the phase error is corrected. Specifying a small value corrects the phase error quickly, but might cause the clock to become unstable.
If the value is too large, it takes a longer time to correct the phase error. The default value on domain members is 1. The default value on stand-alone clients and servers is 7. Note Zero is not a valid value for the PhaseCorrectRate registry entry. PollAdjustFactor All versions Controls the decision to increase or decrease the poll interval for the system. The larger the value, the smaller the amount of error that causes the poll interval to be decreased. RequireSecureTimeSyncRequests Windows 8 and later versions Controls whether or not the DC will respond to time sync requests that use older authentication protocols.
If enabled set to 1 , the DC will not respond to requests using such protocols. This is a boolean setting, and the default value is 0.
SpikeWatchPeriod All versions Specifies the amount of time that a suspicious offset must persist before it is accepted as correct in seconds. The default value on stand-alone clients and workstations is TimeJumpAuditOffset All versions An unsigned integer that indicates the time jump audit threshold, in seconds.
If the time service adjusts the local clock by setting the clock directly, and the time correction is more than this value, then the time service logs an audit event. UpdateInterval All versions Specifies the number of clock ticks between phase correction adjustments. The default value for domain members is 30, The default value for stand-alone clients and servers is , Note Zero is not a valid value for the UpdateInterval registry entry. The default value on stand-alone clients and servers is 1.
The default value on stand-alone clients and servers is 0x1. The NtpServer is a time server that responds to client time requests on the network by returning time samples that are useful for synchronizing the local clock.
LargeSampleSkew All versions Specifies the large sample skew for logging, in seconds. Events will be logged for this setting only when EventLogFlags is explicitly configured for 0x2 large sample skew. The default value on domain members is 3. The default value on stand-alone clients and servers is 3.
ResolvePeerBackOffMaxTimes All versions Specifies the maximum number of times to double the wait interval when repeated attempts to locate a peer to synchronize with fail.
A value of zero means that the wait interval is always the minimum. The default value on domain members is 7. ResolvePeerBackoffMinutes All versions Specifies the initial interval to wait, in minutes, before attempting to locate a peer to synchronize with.
SpecialPollInterval All versions Specifies the special poll interval, in seconds, for manual peers. When the SpecialInterval 0x1 flag is enabled, W32Time uses this poll interval instead of a poll interval determined by the operating system. The default value on domain members is 3, The default value on stand-alone clients and servers is , It contains reserved data that is used by the Windows operating system. It specifies the time, in seconds, before W32Time will resynchronize after the computer has restarted.
Any changes to this setting can cause unpredictable results. The default value on both domain members and on stand-alone clients and servers is left blank. The following registry entries are not a part of the W32Time default configuration but can be added to the registry to obtain enhanced logging capabilities.
By default, the Windows Time service logs an event every time that it switches to a new time source. These are the global Group Policy settings and default values for the Windows Time service.

Any additional feedback? Caution Don't use the Net time command to configure or set a computer's clock time when the Windows Time service is running. Note If you have a computer with multiple network adapters is multi-homed , you cannot enable the Windows Time service based on a network adapter.
Important Windows Server has improved the time synchronization algorithms to align with RFC specifications. Note In this case, if you want to set the clock back slowly, you would also have to adjust the values of PhaseCorrectRate or UpdateInterval in the registry to make sure that the equation result is TRUE.
Note When you remove a Group Policy setting, Windows removes the corresponding entry from the policy area of 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.
