Symptoms: You may notice that when you try to run the Sync command DirectorySyncClientCmd it doesn’t do anything and just closes right away.
If you open your Event viewer you may notice that you are getting the following event
Failed while Purging Run History
at System.Management.ManagementException.ThrowWithExtendedInfo(ManagementStatus errorCode)
at System.Management.ManagementScope.InitializeGuts(Object o)
at Microsoft.Azure.ActiveDirectory.Synchronization.DirectorySyncClientCmd.Program.PurgeRunHistory(TimeSpan purgeInterval)
at Microsoft.Azure.ActiveDirectory.Synchronization.Framework.ActionExecutor.Execute(Action action, String description)
at Microsoft.Azure.ActiveDirectory.Synchronization.DirectorySyncClientCmd.Program.Main(String args)
This happens when the WMI object had unregistered itself which might be caused by another tool installed or uninstalled at the time when the problem started to occur.
To resolve the issue, you ‘ll have to run few command lines… each are explained below
mofcomp “D:\Program Files\Microsoft Azure AD Sync\Bin\mmswmi.mof”
As it shows in the command screenshot below the ‘mofcomp’ parses the MMS (FIM) wmi file and goes through the process of adding the classes to the WMI repository.
regsvr32 /s “D:\Program Files\Microsoft Azure AD Sync\Bin\mmswmi.dll”
Registers the WMI mmswmi.dll file to the server.
net stop winmgmt /y
net start winmgmt
net start “IP Helper”
net start “User Access Logging Service”
net start “Microsoft Azure AD Sync”
D:\Program Files\Microsoft Azure AD Sync\Bin\DirectorySyncClientCmd.exe”
