Group Policy Preference and Scheduled Tasks

For some reason it’s always the details in the basics that are the longest hurdle to get over. This particular topic is something that always needs to be re-googled before the last details are sorted out.


To create a schedule task to either run as the system-account or the interactive user via Group Policy Preference.

The detail:

When resolving SYSTEM the normally resolved identity is BUILTIN\SYSTEM. Interactive is normally not able to resolve at all. This normally results in the following error client side when attempting to apply the Group Policy

‘0x80070534 No mapping between account names and security IDs was done.’

What should be done?

Click the Change User or Group and select the domain of your environment, and proceed to select the Builtin-container. This will resolve both Interactive (running in the user context of the logged on user) and system to NT Authority.






ConfigMgr–User collection and direct membership for Security Group

Roger Zander wrote a brilliant article on Collections in Configuration Manager and some knowledge that aids in designing collection structure to reduce the workload of the ConfigMgr hierarchy.

One thing that I remember evaluating a few years back was to leverage direct memberships to a Active Directory Security Groups to reduce the total evaluation time for collections. After a brief discussion I noted that there wasn’t any guide on howto create this manually (found a scripted method on SCUG.BE) for User Collections.


As a prerequisite the AD Security Group has to be discovered resource. You can review the collection members of “All Users and User Groups” and see what groups are discovered – if what you are looking for isn’t there most likely you are required to tweak the AD Discovery methods you are using.

Create the collection

Once the resource is located you can choose to create a new collection and set the limiting collection to “All Users and User Groups”.


All updates (full and incremental) can be removed to avoid any type of load. Choose to add a Direct Rule.


Change the default search for Resource class and Attribute name to User Group Resource and User Group Name. Enter the value you want and search all the resources you want to select.


Once the collection is created only a single resource is a member:


Ups and downs

The alternative that is mostly used when searching the web is to create a query rule that requires that collection to be updated (either a full schedule, incremental or an external trigger). Whats the difference between these methods?

Query rule

A query requires that AD Discovery has updated the group memberships in the database (full or incremental – both will suffice) and once that is completed the collection has to be updated. Quite common (based on all the blog-articles) is to set an Incremental update for all collections that require a fast update. The limit for this is (according to ConfigMgr 2012 documentation) roughly 200 collections depending and inaddition the queue will increase with updates.

Before the collection reflects the AD Security Group change there has passed a few minutes and once all the bells and whistles are done – the deployment is available for the user.

Direct Rule

A direct rule will not require that the collection is updated at all, however if the AD Security Group is recreated it is required to update the collection with a new direct rule (as the resource will have a new ID).

The user will not receive any deployments until their kerberos ticket has the AD Security Group membership update reflected. Most commonly this only happens during a lock / unlock or logoff / logon.

ConfigMgr site restore and WSUS Catalog version

After you restore a ConfigMgr Primary Site Server there are some losses of information that gets annoying.

Sample; WSUS Catalog version is stored in the registry and the ConfigMgr database. It seems that the registry alone is enough to reset the used WSUS Catalog version, however Registry alone is not enough to restore the catalog version with ConfigMgr 1606.

Roger Zander described the behaviour and gave the right path, however some additional steps were required for ConfigMgr 1606.

Step 1. Identify the necessary catalog version that is required (see Roger Zanders previous description)

Step 2. Update the registry (see Roger Zanders previous description)

Step 3. Update the database. Locate the table dbo.Update_SyncStatus within the ConfigMgr database. Choose Edit Top 200 rows (and there – you are now unsupported by Microsoft).


Update the ContentVersion to match your Catalog Version


Step 4. Trigger a new “Synchronize Software Updates”

Copy a ConfigMgr Application DeploymentType

A small function inspired by Fred Bainbridges post on howto append an OS requirement to a deployment type. The purpose of the function is to copy the Deploymenttype within an application, but if someone feels like a spending a few hours to rewrite it to copy between different applications that could possible work aswell.


function Copy-CMAppDT {
Copy a single Deployment Type within an application
This will create a copy of a DeploymentType, with the lowest priority and the name specified
Copy-CMAppDT -appName "PingKing 2.0.0" -DeploymentType "PingKing 2.0.0" -newDTname "PingKing Updated" -siteCode P01 -siteServer CM01
This is the name of the configmgr application that has the deployment type. This accepts input from pipeline.
.PARAMETER DeploymentType
This is the name of the Deployment Type that you want to copy.
This is the name of the new DeploymentType.
This the ConfigMgr site code you are working with. Defaults to LAB
.PARAMETER siteServer
This the site server you are going to working with.  WMI calls are made to this server.  It is most likely your primary site server.

$siteCode = "LAB",
$siteServer = ""

$connectionManager.Connect($siteServer) | Out-Null

write-verbose "Number of DT: $numDTS"
$dts = $xml.DeploymentTypes

foreach ($dt in $dts)

Boundary Groups and Secondary Sites

After spending a few hours reading about how-to configure Boundaries and Boundary Groups in regards to Secondary Sites in ConfigMgr 2012 I was yet to find something that really made anything explicitly clear. How does a client know that it’s it should be communicating with the Secondary Site?

So far I gathered that Site Assignment can not be conflicting with other boundaries, but Distribution Points can be assigned all over the place.

And you can associate one or more distribution point with each boundary group. You can also add a single distribution point to multiple boundary groups. The default behavior is to choose the closest server from which to transfer the content from. And remember that ConfigMgr 2012 supports that a client is a member of multiple boundary groups for content location, but not for automatic site assignment

From <>

To further understand the site assignment I read the most quoted blog all over the internet. Something’s became more clear – such as the fact that the Primary Site should always be used as the Site Assignment for a boundary.

Note that none of this implies that MPs are located using Content Location Boundary Groups, just the fact that a client is within the scope of a secondary. MP retrieval in ConfigMgr 2012 is not based on client location, just site assignment. The above also does not imply that clients will fallback to a primary site if the MP in the secondary site is down; when an MP at a secondary goes down, clients within the scope of that secondary are essentially on an island unless you change the Boundary Groups and wait for their 25 hour re-evaluation cycle or the clients detect a network change.

From <>

Yet another thread provided some insight into that MPs are actually evaluated if they are part provided as a preferred management point.

  • They enable clients to find a primary site for client assignment (automatic site assignment).
  • They can provide clients with a list of available site systems that have content after you associate the distribution point and state migration point site system servers with the boundary group.
  • Beginning with System Center 2012 Configuration Manager SP2, they support management points and can provide clients with a list of preferred management points.

From <>

This last quote made it click though… If a boundary group is used for both site assignment and for content location the Management Point (of the Secondary Site) should also be specified in the list of Distribution Points.

Here is the conclusion:

Irrespective of the option “Clients prefer to use management points specified in boundary groups” is selected or not selected, If the hierarchy contains a Secondary Site with multiple Boundary Groups associated with it for site assignment, each Boundary Group “MUST” have the Management Point of that Secondary Site is added.

From <>

Well, how does this actually look?


Now, this has to be the piece of historic GUI that simply has been left behind. Its ugly, and no one truly gets this. In the above case – a client that is a member of the above Boundary Group will be communicating to the Secondary Site. I wonder what happens if there are conflicts with assigned MPs…?

The check-mark Use this boundary for site assignment has been recommended to separate into a separate boundary group (gives clarity I suppose). Secondary Sites should never be used for site assignment.I can only assume (based on the last quote I posted above) that if a Site Assignment and a Site Server System are separated the addition of both a Secondary Site MP and a local DP into the Site Systems Server-part are not necessary. I haven’t confirmed this though…

Incase you want to see how many clients are assigned to a specific Management Point a splendid fella just posted a simple SQL-query to identify this.

ConfigMgr and a backlog in distributions


Do you have a primary site and a few secondary sites in ConfigMgr 2012+?

Do you schedule the legacy Package format to update on a schedule?


Do you have a backlog in the distribution manager?

Well, so far this is known (by Microsoft) defect that apparently is yet to be fixed (until 1606 – nothing confirmed beyond that)


If you review the database where ConfigMgr resides you can see that there is a constant growing amount of DistributionJobs. Sample query to get an overview;

use <database>
select COUNT(*) from distributionjobs

The problem grows the more packages you have set to update on a schedule. The frequency of the schedule is not relevant, the package will loop into a forever updating loop. Most likely the primary site will handle this efficiently, however the sending to secondary sites will cause a backlog that is not just an annoyance but causing severe problems as the backlog will continue to grow.

Repeating this: The frequency of the schedule is not relevant. Just check the above checkbox and the issue will occur.

SQL query to locate relevant packages

use <database>
select pkg.PkgID, pkg.Manufacturer, pkg.Name, pkg.Version, pkg.Language, pkg.RefreshSchedule from SMSPackages as pkg
where datalength(pkg.RefreshSchedule) !=0


Easy – uncheck all these check-boxes that updates packages. If you still want to update packages on a schedule use a powershell script to trigger the update and use the task scheduler to run the update.

Run the command-line;

powershell -executionpolicy bypass -file SCCM.UpdatePkg.ps1 -packageid <PACKAGEID>

(I honestly don’t know if I have stolen / copied this from somewhere – if I have give me a ping and I will remove this)

Quick test of WDS

Just a quick-test of a TFTP server – just to validate if it is responsive…

These commands be run from any client (screenshots are from Win7)

Step 1

Install the TFTP Client


Step 2

Run the command in a folder where you have permissions to write in

tftp -1 <servername> GET \boot\x86\

If the TFTP-client is not installed the below error message will be received


If it is successfull, you will have downloaded a small file


Parallels Software Update Point–selfsigned certificate

As a continuation of the previous post on howto setup the Parallels Software Update Point (introduced in Parallels Mac Management for SCCM 4.5) – here comes a minor hack howto enable WSUS for selfsigned certificates and leverage this within Parallels SUP

Step 1.

Enable Selfsigned certificates for WSUS

Set the following registry key

HKLM\Software\Microsoft\Update Services\Server\Setup
DWORD: EnableSelfSignedCertificates – 1

Step 2

Open certmgr.msc where WSUS is installed and export the WSUS selfsigned certificate

Export the WSUS Publishers Self-signed certificate from Trusted publishers to a file. Remember to choose to export the private key…


…and all the extended properties…


… and set a password…


Step 3

Run some code provided by Parallels to set the certificate you just exported as the signing certificate. Replace CERTFILE and CERTPW


$updateServer = [Microsoft.UpdateServices.Administration.AdminProxy]::GetUpdateServer()

$config = $updateServer.GetConfiguration()

$config.SetSigningCertificate("CERTFILE", "CERTPW")

Step 4.

Complete the setup wizard. As you already followed all the previous steps.


Software Center can not be loaded

Regardless of what version of the ConfigMgr agent (2012 –> 1602) you get – there still seems to be a possibility to have left-overs from ConfigMgr 2007.

within the SCClient log-file the following error would be generated;

Exception Microsoft.SoftwareCenter.Client.Data.WmiException: Provider load failure       (Microsoft.SoftwareCenter.Client.SingleInstanceApplication at OnGetException)

The following is presented to the user when starting Software Center


Software Center can not be loaded. There is a problem loading the required components for Software Center.

It seems that this is due to a reference no longer in use – the dcmsdk.dll, located under SysWOW64 (on 32-bit systems). Sample output using reg query:

(Default)    REG_SZ    Configmgr Desired Configuration WMI Provider

(Default)    REG_SZ    C:\WINDOWS\SysWOW64\CCM\dcmsdk.dll

End of search: 2 match(es) found.

Fix? Delete the registry key – sample command line;

reg delete HKLM\Software\Wow6432node\classes\CLSID\{555B0C3E-41BB-4B8A-A8AE-8A9BEE761BDF} /f

App-V 5 and publishing error code: 040000002C.

A minor defect that causes a publishing failure for any packages (only tested for publishing towards a user though. The error code looks like this;

Publish-AppvClientPackage : Application Virtualization Service failed to
complete requested operation.
Operation attempted: Publish AppV Package.
AppV Error Code: 040000002C.
Error module: Virtualization Manager. Internal error detail: 4FC086040000002C.

There seems to already be a few discussions online that assists in resolving the with a few different methods – one seems to suggest to delete a registry key and there is a one that contains a more granular approach by resetting the registry values under LocalVFSSecuredFolders.

A correct view is that each SID under this registry key references the %USERPROFILE%.


and incorrect (and the cause of the error) references the Default-user profile


A quick script (which you can wrap in a Compliance Item or a script – or whatever the preference is..) to remediate this. The actual fix (Set-ItemProperty) is prefixed with # – please test it before you deploy it.

$return = 0
$users = ($k = gi HKLM:\SOFTWARE\Microsoft\AppV\client\Virtualization\LocalVFSSecuredUsers).GetValueNames() | % {

New-Object PSObject -Property @{

Name = $_

Type = $k.GetValueKind($_)

Value = $k.GetValue($_)

} | select Name, Type, Value


foreach ($u in $users) {
if ($u.value -eq 'c:\users\Default\AppData\Local\Microsoft\AppV\Client\VFS') {
$return = 1
#Set-ItemProperty -Path 'HKLM:\SOFTWARE\Microsoft\AppV\client\Virtualization\LocalVFSSecuredUsers' -Name $($u.Name) -value '%USERPROFILE%\AppData\Local\Microsoft\AppV\Client\VFS'



Per the above forum post this should be resolved within App-V 5.0 SP3, however I have still seen minor occurances for later releases – so I wouldn’t call that a  confirmed fix.
