Troubleshooting Client that has NO SCCM Agent in Console BUT still receive deployments



Colleague mine has asked me , why is he getting applications /updates on his computer that he hasn't requested for. When i heard of this ,i  verified in SCCM , based on the computer  name provided and found ,the PC has no SCCM agent .

If the PC has no SCCM agent ,there is no way to receive the deployments. So i asked him to check if these deployments are coming through SCCM/Configmgr or other methods .He confirms that, they are coming from SCCM and his PC has SCCM agent and also apps in Software center.

Screenshot for PC has no SCCM agent installed :


When it was confirmed that ,PC has SCCM agent and is receiving the deployments ,i have decided to take this up further and help to troubleshoot.


When PC has SCCM agent and is healthy , where should we look to fix the issue ? Can we simply uninstall the client and install it back ? does this work ?

I started troubleshooting on the client side by looking at client logs.

1. Review ClientIDManagerStartup.log  --> Records the creation and maintenance of client GUIDS and also the registration status of the client computer.This Can help to troubleshoot scenarios where the client changes its GUID after a hardware change or after Windows activation.

So from this log, i can get the GUID of the computer and check in SCCM,which computer this GUID is assigned to.


you can also get the GUID from smscfg.ini located in C:\windows folder.


Copy the GUID ID and go back to your SQL management studio to find out which computer has this GUID ID.

select name0,SMS_Unique_Identifier0
From v_R_System
where SMS_Unique_Identifier0='GUID:F43BD203-2466-4284-BF28-3A62860C958A'

Run the above Query ,replace GUID ID that you get from log or smscfg.ini file.

This GUID ID assigned to different computer as you can see from below query:


All the deployments that are targeted to this PC are actually hitting problem computer.This is where duplicate or GUID mismatch leads to wrong deployments. you always  need to have operation Collections to identify the duplicate GUID or GUID assigned to multiple computers to avoid these kind of issues.

How do we fix it without reinstalling client ?

Here is simple batch script to stop SMS Agent host ,delete SMSCFG.INI and certificates and start SMS Agent host service to create new GUID (this is not computer GUID).

@echo Off
net stop CcmExec
sleep 5
Reg Delete HKLM\software\Microsoft\Systemcertificates\SMS\Certificates /f
DEL c:\Windows\SMSCFG.ini
sleep 5
net start CcmExec

Open command prompt as administrator and run the above script or command lines .

After you run this script ,monitor ClientIDManagerStartup.log .

After a while ,you will see that, client is now with SCCM client installed and whatever the false deployments on this PC will get disappear from software center in the next machine policy cycle also collection membership update .


Until next time!
