  1. Hi Anoop,
    The company, I’m working for a global acting company and our site is R&D department so I’m not allowed to send any logfiles or so.
    Our global IT faced an issue: The issue is with client signature validation. The validation fails for (most) new clients.
    Now they have installed Configuration Manager 1910 hotfix KB 4538488 and since this has been done we have to contact global team to delete an existing host from SCCM server before redeploying.
    I’m absolutely no SCCM expert but I won’t believe that. Can you confirm this or is it just a misconfiguration (my gut feeling).

    I would be really happy to get an answer from you.


    • The client signature validation fails for all the new clients of a particular site? Unfortunately, without looking into errors, I can suggest or provide a definite answer. Need to understand why do you have signature issue. Do you have duplicate record issue etc

      • I will try to get some log files from client without any domain / hostnames or IP addresses, if this would help.
        As far as I know all sites are affected since they have upgraded to v1910
