Detect ConfigMgr Restart countdown

Finding Lost Boundaries

With everyone shifting around boundaries in ConfigMgr, I thought it would be a good idea to give you way to read the logs to see if you missed a boundary, or if a boundary was missed.

MP_Location.log is updated when clients check-in, this is how they know where they are located.
If you are missing a boundary then download files and tickets are generated.

MP_GetAssignedSite  (<ClientLocationInfo OnInternet="0"><ADSite Name="HOUSTON"/><Forest Name=""/><Domain Name=""/><IPAddresses><IPAddress SubnetAddress="" Address=""/></IPAddresses><BoundaryGroups BoundaryGroupListRetrieveTime="0001-01-01 00:00:00.000"/></ClientLocationInfo>, <BoundaryGroups BoundaryGroupListRetrieveTime="2019-02-08T13:34:09.770"><DOINCServers/></BoundaryGroups>)

CHandleLocationRequest::CreateReply failed with error (80004005).
MP LM: Message discarded

The error "CreateReply failed with error (80004005)" is a good indicator of a problem with a boundary.  Look at the line directly above this and you have the missing boundary.  This could be a Subnet or IP subnet missing.  If you are not discovering them automatically then you need to add it manually.  If you are discovering them automatically, review the schedule. 

This log and move very fast the more machines you have on the MP.  Using this information boundaries can be auto create and even a notification sent that a boundary was missing but it was created for you.

Windows as a Service: Forcing machine forward

Do you have a Windows as a Service strategy lined out? 
How do you are going to push the upgrades. 
Are you going to allow everyone to upgrade to any version or control it? 
What are you doing about special machines you cannot force due to software or process control, are they moving at the end of cycle? 
Are you tracking which machines are out of compliance?

I bet that last question made you think.  Many companies have not tracked their end of life for Windows 10 which can be found here:

Now you can create a CI and pull machines into a collection that will soon be end of life, use this to force a popup, Toast Notification, force the upgrade, etc...


CI Discovery script
Data type:String
 $Win10_Life = @(
                 ("1607","1703","1709", "1803","1809","1903","1909"),
                  ("4/9/2019","10/8/2019","4/14/2020","11/10/2020","5/11/2021","12/8/2020","5/10/2022") )

$CurentWindowsVer = (Get-ItemProperty 'HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion' -Name ReleaseID -ErrorAction Stop).ReleaseID

$index= 0..20 | Where { $Win10_Life[0][$_] -eq $CurentWindowsVer }
if ($index -ge 0)
  # grab the end of life date for the OS version
  $EndofLifeDate= $Win10_Life[1][$index]

  #determine number of days left in life
  $EndofLifeDays = (New-TimeSpan -Start (Get-Date) -End $EndofLifeDate).Days


    If ($EndofLifeDays -lt 60) {"Upgrade"}

You can see there is a 2 Dimension array with the build numbers and the end of life date.  If you are running Pro then you will need to change these dates, these are for Enterprise/Education. 

 In the Compliance setting I use 
"The value returned by the specified script:"
Not Equal to

This can be run once a month or every 3 weeks on a machine.  It will pull the machine into the collection if it has less than 60 days. 

How do I create the collection?
In the baseline right click on the deployment
Select the Non-Compliant. 

This will create a collection of machines that are not running a supported version of Windows 10.
