Machines with Duplicate SMS UI GUIDs

I hope that someone can help me with my issue.

I started to notice that some of the machines that I have were not installing the configmgr client and that some were showing up in the all devices pool twice, one entry showing installed and active and the other as not installed. I have used a lot of the links and help articles that I have found to try to correct the duplicate SMS UI GUID's and nothing helped. I think that my issue is the amount of Client licenses that my network purchased, but I am not sure how to confirm that.

Do you happen to know how to find out the amount of CML's that are in use and the total that can be allocated from a PS command?

My reasoning that I think that it is a license issue or CML issue is that I have 3 different device pools and adding up the three pools I get 20 windows 7 machines with correct and working configmgr installs. I have a total at this time of 50 windows clients.

What I noticed is that if I run these steps that SMS UI GUID will change, but it will then revert to a SMS UI GUID that is in use by the 20th machine.

Delete the SMSCFG.ini

Run ccmdelcert.exe

Stop SMS service then restart the SMS service

run Tranguid.exe /R

When this happens I can see that it will create a new SMS UI GUID, but then when the service is restarted again or if I wait long enough the SMS GUID will change the new SMS UI GUID to the previous SMSUID and create a new SMS UI GUID with the same number as the 20th workstation.

Now to the point where I think that it is a licensing issue is that if I uninstall Configmgr from a working client I can then add one more existing machine and it will work without an issue. When I try to add in a 21th machine it will not install with its own SMS UI GUID it will use the 20th machine SMS UI GUID.

All of the machines are from a image. I did not install the configmgr client in the image and the image does complete a sysprep after the image completes and I have verified that the machines SID and GUID's are different.

Thank you for any help.

This is totally unrelated to an amount of licenses. The ConfigMgr client (or even server) is not aware of that. 
Have you already examined the logs (e.g. ClientIDManagerStartup.log) when this issue happens?

This is what I am seeing, but I am not sure what the root cause is at the moment.

I have two machines with the same SMS UI GUID and then my machine that is working fine. The two machines that share the same SMS UI GUID have the following line in the log that you said to check.

<! [LOG[ [RegTask] - Client is not registered. Sending registration for GUID: 76FF4C21-75CA-4611-A612-E9F522CBA830 ... ]LOG] !><time='07:01:51.231+240' date="04-27-2015"

My machine:

I am also getting this error on the duplicate clients as well as my machine which is working. Unable to find PKI certificate matching SCCM certificate selection criteria 0x87d00280

How was the OS deployed on these systems?

Do you have HTTPS client communication enabled in the site? Specifically, do you have the check box to enable client certificate use checked?

looking at the settings on the SCCM server for the site I have HTTPS or HTTP selected

Both use PKI Client Certificate (client authentication capability) when available and Clients check the certificate revocation list (CRL) for site systems are checked.

I am going to test with both of the above unchecked to see if that happens to make a difference. what is odd is that the initial 20 machines installed and are working fine with the above selection its just when I get over 20 it runs into the issue of a duplicate SMS UI GUID.

Do you clients have PKI client auth certs on them?

What about my first question?

Sorry about that.

Image was done with MDT and WDS.

At this point we do not have a CA for the windows side. But to answer your question on PKI client auth certs I want to say no. if you have a specific location for me to check I will and let you know the result.

Also my machine that is working with SCCM 2012 was imaged from the same image

Could it be a firewall issue? I noticed another thread that pointed to that. The machines are in other locations with routers and other devices that we cannot manage. 


I am going to update the SCCM server to CU4. I happened to notice that the application has not been updated since it has been installed. May not correct the issue, but it needs to be updated any way.
