  • Server Manager refresh failed error

    Server Manager refresh failed error

    When opening Server Manager on the server, in the notifications you will see an error stating Refresh Failed.

    At this stage, you will not be able to add any features to the server and you will not be able to add or remove windows features.

    A pop-up about collecting inventory data and a refresh error saying “Configuration refresh failed with the following error: Invalid class” will show.

    Before proceeding you can take a backup of this by using the command below
    winmgmt /backup %computername%_MM_DD_YEAR.WMI_backup

    To fix the problem you would need to do the following in a command prompt as Administrator.

    winmgmt /verifyrepository
    winmgmt /salvagerepository
    winmgmt /resetrepository

    This will resolve the problem and when you relaunch the Server Manager, you will be able to add the features with no issues.

    Install Module with PowerShell: NuGet Unable to download, check your internet connection

    While installing the NuGet PowerShell module, you will get the following error

    WARNING: MSG:UnableToDownload «https://go.microsoft.com/fwlink/?LinkID=627338&clcid=0x409» «»
    WARNING: Unable to download the list of available providers. Check your internet connection.

    To resolve the problem open a PowerShell window as Administrator and enter the following command.
    [Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12

    This will resolve the problem temporarily as if you would run the command again, it will still prompt the same problem. To resolve the issue permanently, you need to update the registry by running the below command to update the registry.

    Set-ItemProperty -Path 'HKLM:\SOFTWARE\Wow6432Node\Microsoft\.NetFramework\v4.0.30319' -Name 'SchUseStrongCrypto' -Value '1' -Type DWord

    Set-ItemProperty -Path 'HKLM:\SOFTWARE\Microsoft\.NetFramework\v4.0.30319' -Name 'SchUseStrongCrypto' -Value '1' -Type DWord

    Close all PowerShell windows and try again with the following command to confirm that the protocol has been updated.

    [Net.ServicePointManager]::SecurityProtocol
