DSC Doesn't seem to restore the configuration

DSC
#1

Hi Everyone!

Recently i started to follow the Powershell:Beginner learningpath and got stuck at the DSC part.
I followed the following steps:

Step 1:

configuration Configname {
Import-DscResource -ModuleName 'PSDesiredStateConfiguration'
    Node $Computername {
        Windowsfeature IIS{
            Name = 'web-server'
            Ensure = 'Present'
        }
    }
}
$computername = 'serverx'
ConfigName -outputpath c:\DSC\Config

Result:

Mode                LastWriteTime         Length Name                                                                                                                                         
----                -------------         ------ ----                                                                                                                                         
-a----       12/05/2017     13:45           1858 serverx.mof

Step 2:

Start-DscConfiguration -Path C:\DSC\Config\ -ComputerName 'serverx' -Verbose -Wait

Result: Installation of the Web-server feature has succeeded.

Step 3:

Invoke-Command -ComputerName serverx {Remove-WindowsFeature -Name web-server -Restart}

Result:

Success Restart Needed Exit Code      Feature Result                                PSComputerName

WARNING: You must restart this server to finish the removal process.

Server rebooted and the feature was indeed removed

Step 4:

Test-DscConfiguration -CimSession nl-wrt-oefen

Result: False

And there is the problem, it doesn’t seem to restore. Not even after about 15 minutes.
Anyone any suggestions on what i’m doing wrong?

Hi There!

Recently i started the PowerShell: Beginner learning path and got stuck at the DSC part.

I followed the following steps:

Step 1:

configuration Configname {
Import-DscResource -ModuleName 'PSDesiredStateConfiguration'
    Node $Computername {
        Windowsfeature IIS{
            Name = 'web-server'
            Ensure = 'Present'
        }
    }
}
$computername = 'serverx'
ConfigName -outputpath c:\DSC\Config

Result:

Step 4:

Test-DscConfiguration -CimSession serverx
False

and there lies the problem, even after 15 minutes or longer i still get the “false” and the web-server feature isn’t restored.

Anyone any suggestions on what i’m doing wrong?

What is the LCM set to “Get-DscLocalConfigurationManager” under ConfigurationMode? In order for it to auto re-run this would need to be set to “ApplyAndAutoCorrect”

What happens if you re-run “Start-DscConfiguration -Path C:\DSC\Config\ -ComputerName ‘serverx’ -Verbose -Wait”
