Performs a configuration check on a computer that is using DSC's Pull refresh mode.


Start-DscPullConfiguration -ComputerName <String[]> [-Credential <PSCredential>] [-ModuleName <String[]>] [<CommonParameters>]
Start-DscPullConfiguration [-CimSession <CimSession[]>] [-ModuleName <String[]>] [<CommonParameters>]


The most frequently a computer's LCM will download new configuration is every 15 minutes; the most frequently it will apply it is every 30 minutes. This function contacts a computer's LCM and tells it to apply and download its configuration immediately.

If a computer's LCM isn't configured to pull its configuration, an error is written, and nothing happens.

If a configuration check fails, the errors are retrieved from the computer's event log and written out as errors. The Remote Event Log Management firewall rules must be enabled on the computer for this to work. If they aren't, you'll see an error explaining this. The Get-DscError help topic shows how to enable these firewall rules.

Sometimes, the LCM does a really crappy job of updating to the latest version of a module. Start-DscPullConfiguration will delete modules on the target computers. Specify the names of the modules to delete with the ModuleName parameter. Make sure you only delete modules that will get installed by the LCM. Only modules installed in the $env:ProgramFiles\WindowsPowerShell\Modules directory are removed.

Start-DscPullConfiguration is new in Carbon 2.0.
