2
Enable SMB delegation on Active Directory using either of the following approaches:
•
Run the following command on Active Directory. Visit Enable-SmbDelegation for details.

Foglight for Hyper-V WinRM GPO script

The GPO script is provided to allow for a streamlined deployment, including how to configure Windows Remote Management (WinRM). Users must run the script as the Administrator on the AD controller which is enabled on Windows Server 2008 R2, Windows Server 2012 or Windows Server 2012 R2. They must enable WinRM for all the Hyper-V® servers through one time setup at Domain Controller, login to just one Domain Controller, and change the group policy by running an automation script.

The script creates a group policy object and links it to the specific OU (specified by running the script). The policy has the following settings:

•
Create a firewall rule “Allow WinRM for FglAM Requests” which allows port 5985 on all network.
•
Allow WinRM basic authentication.
•
Allow WinRM unencrypted traffic.
•
Set WinRM IPv4 and IPv6 filter to “*”.
•
At the end of the script, users can chose to force the policy update. It runs an “Invoke-GPUpdate” method on all members in the specific OU.

These settings can be observed in the Group Policy Management console by selecting the policy object.

To undo the changes made by the script:
•
Delete the group policy object.
OR
•
Remove the linked OU from the GPO scope.
