Why is Windows DSC LCM running every 5 hours - windows

Question

I have two servers running Windows DSC that should both be running every 15 min but one is running correctly and the other is running ever 5 hours for some reason yet to be discovered. Here are the two LCM configurations:
The one that works:
PS C:\WINDOWS\system32> Get-DSCLocalConfigurationManager
ActionAfterReboot : ContinueConfiguration
AgentId : 420E62A0-FE64-11F5-9732-003ADC065DC3
AllowModuleOverWrite : False
CertificateID :
ConfigurationDownloadManagers : {}
ConfigurationID : 82xx1e91-4bz8-4fe4-b8dc-o73bc77c8756
ConfigurationMode : ApplyAndAutoCorrect
ConfigurationModeFrequencyMins : 15
Credential :
DebugMode : {NONE}
DownloadManagerCustomData : {MSFT_KeyValuePair (key = "ServerUrl"), MSFT_KeyValuePair (key =
"AllowUnsecureConnection")}
DownloadManagerName : WebDownloadManager
LCMCompatibleVersions : {1.0, 2.0}
LCMState : Idle

StatusRetentionTimeInDays : 10
PartialConfigurations :
RebootNodeIfNeeded : False
RefreshFrequencyMins : 30
RefreshMode : Pull
ReportManagers : {}
ResourceModuleManagers : {}

The one that is not:
PS C:\WINDOWS\system32> Get-DSCLocalConfigurationManager
ActionAfterReboot : ContinueConfiguration
AllowModuleOverWrite : False
CertificateID :
ConfigurationDownloadManagers : {}
ConfigurationID : 814b8ec2-7c1b-2359-8342-4ec23a4e576b

Not sure why the second one is running ever 5 hours as it looks to be configured for every 15 min.... any ideas?

Answer 1

If it is WMF 5.0 RTM, you can check the configuration frequency settings as seen by the timers itself using:
get-winevent -LogName Microsoft-Windows-DSC/Operational | where {$_.Id -eq 4309}
This event contains information about the frequency of the timer as seen by the timer that triggers the consistency.
If the value is not 15 min, perform Set-DscLocalConfigurationManager again on the affected node and check the event again.
If the value is 15 min, look for 2 more events indicating a consistency run( you want the one with flag 1 for consistency check):
get-winevent -LogName Microsoft-Windows-DSC/Operational | where {($_.Id -eq 4343)-or ($_.Id -eq 4312)}
