Occassionally the above message also end with "the specified user does not exist" or ". The change is scheduled to be done next week so I'm hoping to get things as much in line as possible before then. So what are these That means your PDCE is not getting tim from external at all. Secondly, if those I am only at this client on a limited basis so I don't have a lot of details but it is my understanding that those two servers -the I have asked them to verify that UDP port is open.
Those two servers are not technically external since they are obviously on the internal LAN but those servers do sync to an external source and are the servers they want to be the time servers for the PDC. Does it matter that they are not on an external network? In other words, as long as they are 'external' to the PDC and are truly reliable time servers, shouldn't that work just fine?
Is there a way I can tell if those time servers are the 'right' sort of time servers? They obviously show up in the registry but are they giving the right sort of reply to the PDC? I will be making this change today. Turns out the time source is a Cisco appliance.
I believe it is a Cisco switch. I suspect the issue might be how this device and the Windows servers are communicating. I'll have to see what comes of it when I make the changes above, reset everything and try to resync things up.
Upon further investigation, I find that this client has a setting in the Default Domain policy to apply sntp settings. I originally looked for this in the default domain controller policy and didn't find it per article KB, then found it in the default policy.
So, I will remove those settings and retry syncing the time again. Unfortunately this client has fairly strong change management requirements so it will probably be a week before I can perform the changes.

Sync Your Server Time. Computers , Windows. Attention: This content is 13 years old. Please keep its age in mind while reading as its contents may now be outdated or inaccurate. It contains reserved data that is used by the Windows operating system, and any changes to this setting can cause unpredictable results. MaxAllowedPhaseOffset All versions Specifies the maximum offset in seconds for which W32Time attempts to adjust the computer clock by using the clock rate.
When the offset exceeds this rate, W32Time sets the computer clock directly. The default value for domain members is The default value for stand-alone clients and servers is 1. 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.
