    Hello,

    Sorry was reading this as still part of the setup issue. More details on the issue would be helpful. I this is happening during setup there should be another setupact.log file on your system, probably in the \windows\panther folder. The attached ones only apply to the first phase of setup.

    Check this thread for the Event IDS of the join and disjoin of domain.

    Hi Team,

    I have performed In-Place Upgrade after following below steps, but still the issue persist. So request you to provide detailed steps further to upgrade the OS.

    Also tried with below steps but facing with same issue again the server upgrade continues till 60% in VM console and restarted the Oerating system and then Undo the changes performed untill then.

    • Uninstall any third-party antivirus, VPNs, or system-level tools
    • Remove any unused or custom printer drivers, especially tools
    • Disconnect all non-essential peripherals such as USB devices, smart card readers, or external drives.

    Hi Pramod,

    The error you’re seeing is often caused by third-party drivers or software that interfere with the upgrade process especially during in-place upgrades.

    Before digging into detailed log files like setuperr.log or setupact.log, I recommend starting with a few basic cleanup steps. These often help identify and resolve common blockers without much effort.

    Clean up drivers and software

    • Uninstall any third-party antivirus, VPNs, or system-level tools
    • Remove any unused or custom printer drivers, especially tools
    • Disconnect all non-essential peripherals such as USB devices, smart card readers, or external drives.

    Disable non-microsoft services

    • Open an elevated Command Prompt or PowerShell and type: msconfig
    • Go to the Services tab.
    • Check Hide all Microsoft services at the bottom.
    • Click Disable all, then Apply and reboot the system.

    Hope this helps!
