DSC and installing Windows Features from CAB file

[Rob Sterenborg]

Hi,

I'm in the process of migrating from old to new DSC modules, and I'm running into an issue when installing Windows Features.

I need feature "NET-Framework-Core" installed (so, .NET Framework 3.5). I'm installing this feature from a CAB file because this doesn't work from "Install-WindowsFeature", and I'm coming from "dsc_windowsoptionalfeature", which had a "source" parameter which "dsc_xwindowsoptionalfeature" doesn't have.

The Puppet code reads:

```
dsc_xwindowspackagecab {'NET-Framework-Core':
dsc_ensure => 'Present',
dsc_sourcepath => 'C:\Temp',
dsc_name => 'microsoft-windows-netfx3-ondemand-package~31bf3856ad364e35~amd64~~.cab',
dsc_logpath => 'C:\Temp\microsoft-windows-netfx3-ondemand-package~31bf3856ad364e35~amd64~~.log',
}
```

I keep getting:

```
Notice: /Stage[main]/Platform::Pre::Windows_features_role/Dsc_xwindowspackagecab[NET-Framework-Core]/dsc_logpath: dsc_logpath changed to 'C:\Temp\microsoft-windows-netfx3-ondemand-package~31bf3856ad364e35~amd64~~.log' (corrective)
Notice: /Stage[main]/Platform::Pre::Windows_features_role/Dsc_xwindowspackagecab[NET-Framework-Core]/dsc_ensure: dsc_ensure changed 'Absent' to 'Present' (corrective)
Notice: dsc_xwindowspackagecab[{:name=>"NET-Framework-Core", :dsc_name=>"microsoft-windows-netfx3-ondemand-package~31bf3856ad364e35~amd64~~.cab"}]: Creating: Finished in 8.88 seconds
```

Powershell shows the feature is installed, when it wasn't before:

```
PS C:\Windows\system32> (Get-WindowsFeature -Name NET-Framework-Core).InstallState
Installed
```

So I checked DSC as derived from the Puppet Agent debug trace output:

```
$InvokeParams = @{
Name = 'xWindowsPackageCab';
Method = 'get';
Property = @{
ensure = 'Present';
sourcepath = 'C:\Temp';
name = 'microsoft-windows-netfx3-ondemand-package~31bf3856ad364e35~amd64~~.cab'
};
ModuleName = @{
ModuleName = 'C:/ProgramData/PuppetLabs/puppet/cache/lib/puppet_x/xpsdesiredstateconfiguration/dsc_resources/xPSDesiredStateConfiguration/xPSDesiredStateConfiguration.psd1';
RequiredVersion = '9.1.0'
}
}

Invoke-DscResource @InvokeParams

ConfigurationName :
DependsOn :
ModuleName : C:/ProgramData/PuppetLabs/puppet/cache/lib/puppet_x/xpsdesiredstateconfiguration/dsc_resources/xPSDesiredStateConfiguration/xPSDesiredStateConfiguration.psd1
ModuleVersion : 9.1.0
PsDscRunAsCredential :
ResourceId :
SourceInfo :
Ensure : Absent
LogPath :
Name : microsoft-windows-netfx3-ondemand-package~31bf3856ad364e35~amd64~~.cab
SourcePath : C:\Temp
PSComputerName : localhost
```

DSC says that LogPath is empty, and that Ensure is Absent. Not what I expected.
The logfile as used in the code is written and contains lots of lines; lines are added with every Puppet Agent run.

I'm using Puppet Agent 6.26 with Puppet Server 6.17.1.

Can anyone hint me to what I'm missing?


Thanks,
Rob
