Like all Windows software, DSC records errors and events in logs that can be viewed from the Event Viewer. Examining these logs can help you understand why a particular operation failed, and how to prevent failure in the future.
In Event Viewer, DSC events are in: Applications and Services Logs/Microsoft/Windows/Desired State Configuration
Maybe you can also try using the Get-DscConfigurationStatus cmdlet to get information about configuration status from a target node and see if are some issues there. You can dig into the object to discover details about the configuration run such as:
-All of the resources that failed
-Any resource that requested a reboot
-Meta-Configuration settings at the time of configuration run.
Hope this resolves your Query!!
