DSC Troubleshooting

If you want to troubleshoot DSC (Desired State Configuration)… You can easily run a DSC config script locally on your computer, apply the MOF manually on-demand and watch it apply in realtime as per the below.

The below are the lines of PowerShell code you need for testing. First though, make sure you run the entire DSC Configuration block of code – so it’s in memory, similar to how a function behaves. In the example below, my DSC configuration file is called ‘Main‘.

################################################################################
################## Compile the DSC Configuration & Generate the MOF file
################################################################################
$ComputerName = $env:COMPUTERNAME
Main nodeName $env:COMPUTERNAME OutputPath "$env:USERPROFILE\Desktop"
################################################################################
################## Apply the MOF file to the local computer
################################################################################
# DSC – Watch as it applies the MOF
Start-DscConfiguration Path "$env:USERPROFILE\Desktop" ComputerName $ComputerName Wait Verbose Force
# LCM – Apply
<#
LCM stands for: (Local Configuration Manager) this congured the local machine for DSC,
You could probably skip the LCM part in testing
#>
Set-DscLocalConfigurationManager Path "$env:USERPROFILE\Desktop" ComputerName $ComputerName Verbose Force
# LCM – Check
Get-DscLocalConfigurationManager
################################################################################
################## Troubleshooting DSC Application

################################################################################
