ConfigMgr 2007: Clients not installed - RegTask: Failed to get certificate. Error: 0x80004005

  • Article

We're starting to see a couple of these issues roll in so I thought a heads up might be in order.  This solution comes from Brian Shaw, one of our top gun support Engineers our in Charlotte, NC:

========

Issue: Some clients may not show as being installed when viewed through the System Center Configuration Manager 2007 admin console.  From the target computers themselves the agents appear to function properly. When viewing the ClientLocation.log file you may also see the following error:

RegTask: Failed to get certificate. Error: 0x80004005

Cause: This is caused by an issue with the RSA machine keys on the client.

Resolution: To resolve this issue complete the following steps:

  1. Backup all files in the C:\Documents and Settings\All Users\Application Data\Microsoft\Crypto\RSA\MachineKeys folder (or the corresponding folder on your specific clients).
  2. Restart the SMS Agent Host Service to recreate these certificates.
  3. At this point the clients should start showing up in the console.  If not, remove and push the client agent to the affected computers again.

========

I hope you don't get this issue yourself but if you do then at least know you'll know how to fix it.  Thanks Brian!

Enjoy!

    I'm not sure I purchased the Reg Task but if I did, please cancel it at once.  I'm having health problems and moving into a nursing home soon.  Please refund my money if I purchased this plan as I won't be able to use it.  If it shows on the my credit statement, I'll have to have them cancel it.   Thank you, Barbara

    Brilliant fix - I had a client with the same issue and deleting those RSA keys fixed the problem. Thanks again! Chris.

    regtask found almost 2000 errors in my PC and when I bought the product and received the key it didn't work! That key cost me 41 dolars and I can use it because of this problem. regtask wants me to spend another 40 d0llar in order to get another key.

    This is an irresponsible post. true, this will work on some servers....but it is a barbaric way to go about it and can result in serious certificate issues w/ IIS servers,lync servers,etc. What you're advising here does not account for any private keys. The CORRECT was to go about this would be as follows: Open MMC Add certificates snap-in manage certs for computer find SMS cert and delete it re-start SMS agent host This will achieve the desired result w/o trashing your other certificates in the process. This post should either be amended or removed. Bad advice.

    ¡Brillante! Respaldé toda la carpeta MachineKeys y después la eliminé; Reinicié el servicio SMS Agent Host y el problema fue resuelto. Gracias, llevaba dos días con esto.

    U.R. Wrong's flamboyance aside, they are correct that this is not the correct solution. The steps U.R. gives are the correct ones, and the SMS cert that should be deleted is: 19c5cf9c7b5dc9de3e548adb70398402_f985961b-8296-47d8-8148-6cd13ba897aa Then restart the CCM agent service and the certificate will be recreated.

    It worked for me but, in my case the GUID has been missing in the SCCM 2007 client and I have tried to backup the Machine keys first and then reinstalled the client again. The client was started showing again on the SCCM console.
    Thanks for your help.
