WindowsFeature Absent should account for 'removed' as well

[ewhitesides]

When I declare a simple resource such as this:

WindowsFeature RemoveTFTP {
    Name = 'TFTP-Client'
    Ensure = 'Absent'
}

I get returned that the resource is not in desired state (from get-dscconfigurationstatus) when applying this to 2016 servers without a GUI, because apparently by default this feature is removed, not available, etc.

To me, if the feature is removed, that also qualifies as absent, so it should return that it is in the desired state.

output from a similar setting I had set on 'PNRP' feature:

Message System.InvalidOperationException: The requested feature PNRP could not be found on the target machine.

I had to do the following to overcome the issue:

#Disabled Features (STIG Requirements) $DisabledFeatures = @( 'Simple-TCPIP' 'Telnet-Client' 'PNRP' 'Web-Ftp-Server' 'Web-Ftp-Service' 'Web-Ftp-Ext' 'TFTP-Client' 'Fax' 'RSAT-Fax' ) Script Remove_Disabled_Features { #Using script resource because some features are not available at all, and windowsfeature resource reports error in configuring #'$.InstallState -match '^Install' covers Install and InstallPending GetScript = { #Do Nothing } SetScript = { $Installed_Features = Get-WindowsFeature | Where-Object {$.Name -in $Using:DisabledFeatures -and $.InstallState -match '^Install'} ForEach ($Feature in $Installed_Features) {Uninstall-WindowsFeature -Name $Feature} } TestScript = { $Installed_Features = Get-WindowsFeature | Where-Object {$.Name -in $Using:DisabledFeatures -and $_.InstallState -match '^Install'} if ($Installed_Features) {return $false} else {return $true} } }
