WinRM on a computer in an AD domain

This guide is an aid to perform basic configuration of WinRM, but you will need to adjust the settings for your environment should you require any particular parameters.

To sum up:

1. Create a Group Policy object for the Active Directory® (AD) domain to which the computer belongs (note the time it may take for changes to propagate).
2. Edit the item created in step 1 with the services required for WinRM.
3. Create rules in the Firewall (of the operating system) to allow the incoming connection.

Creating a Group Policy

• Go to the MS Windows Control Panel and open Administrative Tools.
• Open Group Policy Management and select the domain the computer belongs to.
• Click with the secondary mouse button (secondary-click) and select Create a GPO in this domain.
• Enter "Enable WinRM" and click OK.
