    Hi @Md. Mohsin Reja ，

    Regarding this Event ID: 4627, multiple users report experiencing the same issue:

    event id 4768 - Microsoft Q&A

    Event ID 4768 with error "0x6" - Microsoft Q&A

    From the discussion, it can be seen that the error will not affect the environment. Therefore, if the server does not have other errors that affect usage, it is recommended that you can ignore this event.
