    I have a DSC partial configuration script that I am trying to develop. It fails at the point of configuring the LCM.

    Here is the meta config block and script to configure SRV2.

    [DSCLocalConfigurationManager()]
    Configuration SRV2WebPullPartial {
    Node Srv2 {
      Settings
          {  RefreshMode          = 'Pull'
             ConfigurationModeFrequencyMins = 30
             ConfigurationMode    = 'ApplyandAutoCorrect'
             RefreshFrequencyMins = 30 
             RebootNodeIfNeeded   = $true 
             AllowModuleOverwrite = $true }
      ConfigurationRepositoryWeb DSCPullSrv
         {   ServerURL = 'https://SRV1:8080/PSDSCPullServer.svc'
             RegistrationKey = '5d79ee6e-0420-4c98-9cc3-9f696901a816'
             ConfigurationNames = @('NetworkConfig','ServiceConfig')  }
      PartialConfiguration NetworkConfig
         {  Description = 'Network Configuration'
            Configurationsource = @('[ConfigurationRepositoryWeb]DSCPullSrv')}
      PartialConfiguration ServiceConfig {
            Description = 'Service Configuration'
            Configurationsource = @('[ConfigurationRepositoryWeb]DSCPullSrv')
            DependsOn   = '[PartialConfiguration]NetworkConfig'}
      } 
    }
    
    # 8. Create MOF to config DSC LCM on SRV2
    Remove-Item C:\DSC\* -Rec -Force 
    Remove-Item '\\srv2\c$\Windows\System32\Configuration\*.mof'
    $Guid = '5d79ee6e-0420-4c98-9cc3-9f696901a816'
    SRV2WebPullPartial -OutputPath C:\DSC -Guid $Guid
    
    # 9. Config LCM on SRV2:
    $CSSrv2 = New-CimSession -ComputerName SRV2
    Set-DscLocalConfigurationManager -CimSession $CSSrv2 `
                                     -Path C:\DSC `
                                     -Verbose
    
    
    
    When The last step runs, I get an error:
    
    
    VERBOSE: Performing the operation "Start-DscConfiguration: SendMetaConfigurationApply" on target "MSFT_DSCLocalConfigurationManager".

    I'm sure I'm making a silly mistake, but I just can't see it., Clues??

    Hello!

    Why do you use both GUID and Configuration names ?

    Try to run this directly on your node:

    [DSCLocalConfigurationManager()]
    Configuration SRV2WebPullPartial {
    Node Srv2 {
      Settings
          {  RefreshMode          = 'Pull'
             ConfigurationModeFrequencyMins = 30
             ConfigurationMode    = 'ApplyandAutoCorrect'
             RefreshFrequencyMins = 30 
             RebootNodeIfNeeded   = $true 
             AllowModuleOverwrite = $true }
      ConfigurationRepositoryWeb DSCPullSrv
         {   ServerURL = 'https://SRV1:8080/PSDSCPullServer.svc'
             RegistrationKey = '5d79ee6e-0420-4c98-9cc3-9f696901a816'
             ConfigurationNames = @('NetworkConfig','ServiceConfig')  }
      PartialConfiguration NetworkConfig
         {  Description = 'Network Configuration'
            Configurationsource = @('[ConfigurationRepositoryWeb]DSCPullSrv')}
      PartialConfiguration ServiceConfig {
            Description = 'Service Configuration'
            Configurationsource = @('[ConfigurationRepositoryWeb]DSCPullSrv')
            DependsOn   = '[PartialConfiguration]NetworkConfig'}
      } 
    }
    SRV2WebPullPartial
    Set-DSCLocalConfigurationManager localhost –Path .\SRV2WebPullPartial –Verbose -Force
