duplicate guid in SCCM 2012 R2

[taylormcc]

Hi, I am running SCCM 2012 R2 and I have an issue with duplicate GUIDs. At any given time, only one of this group of machines appear in the SCCM console.

The machines were unfortunately made from the same image that already had a SCCM client installed on it.

I have tried the following on the client:

stop the sms agent host service

delete smscfg.ini

delete the certificates from the sms certificate store

run ccmdelcert on the machine

run tranguid /r

uninstall the client

reinstall the client

 

 

After this, the machines still have the same:

SMS Unique Identifier

SMS Hardware Identifier 2

 

And they still only one of them shows up at a time in the console

 

Please help me to resolve this issue

Thanks

After some testing I found that I can cause the client to generate a new GUID, but the moment it connects to the server, the GUID in smscfg.ini is replaced with the bad common GUID.

Hi, can anyone help me with this?

Thank you very much.

Stop the SMS Agent Host service. Run CMD as admin and run "c:\windows\ccmsetup\ccmsetup.exe resetkeyinformation=true"

Hi Jorlando,

Thank you so much for your suggestion. I tried this on 4 of the 17 computers that are having this problem.

 

Unfortunately, after the ccmsetup completes, the computers still have the same guid. They do not uniquely show up in the console.

 

Do you have any other suggestions?

 

Thanks,

Taylor

This is what shows up in the ClientIDManagerStartup log

I can make the client think that it should have a new GUID, but as soon as it communicates with the server, the server assigns it the old bad common GUID.

I have deleted all of the clients from the SCCM console, but they seem to be lingering in the server database.

Hi, can anyone please help me with this? Any insight would be deeply appreciated.

If I am not supplying enough information then please let me know.

Thank you

have you tried the below:-

 

Identify the systems with a duplicate GUID

1. Delete the c:\windows\smscfg.ini file from the client
2. Run CCMDELCERT on the client (*)
3. Restart the SMS Client agent (SMS Agent Host)
4. A new GUID will be generated

Hi, thank you for your suggestion. When I do this, the client temporarily gets a new GUID. Once it has contacted the server, the server assigns it the old common GUID.

The ClientIDStartupManager.log shows the following:

<![LOG[[RegTask] - Client is not registered. Sending registration request for GUID:45E5384F-3D9F-4C0F-B40A-9C14EA574785 ...]LOG]!><time="10:13:59.626+240" date="09-03-2014" component="ClientIDManagerStartup" context="" type="1" thread="3488" file="regtask.cpp:1609">

Where 45e53... was the new GUID

and 19ce60... was the bad old common GUID.

 

Thanks again.

Does anyone else have any insight on this? We are going to be opening up a support case with Microsoft for this but I would like to try everything possible before making the call.

Thank you in advance.
