There are a few things that we highly recommend you to have in place in order for DSC to work.

• All nodes that will be used to author, push, or receive configurations are running WMF version 5.1 or later.

• WS-Management (WS-MAN) traffic is permitted on the network. It will be enabled by default on nodes that have PowerShell version 5 installed, but you must ensure it’s not being blocked by firewalls or other network elements. Read further for more information.

• Authoring nodes that are used to write configurations need to have internet connectivity to download new DSC-related resources.

• The nodes that are connected to config.XO need to have internet access via port 443 to our backend.
