New-DSCCheckSum generates checksum files for Desired State Configuration documents and compressed Desired State Configuration resources.

The cmdlet generates a checksum file for each configuration and resource to be used in pull mode. The DSC service uses the checksums to ensure that the correct configuration and resources exist on the target node. Place the checksums along with the associated DSC documents and compressed DSC resources in the Desired State Configuration service store.

Examples

Create checksum files for all configurations in a specific path, skipping any that already exist in the destination:
PS C:\> New-DscCheckSum -ConfigurationPath C:\DSC\Configurations\

Create checksum files for all configurations in a specific path and overwrite any that already exist in the destination:
PS C:\> New-DscCheckSum -ConfigurationPath C:\DSC\Configurations\ -Force
