You can download the script from here
After running the script my client’s became back Healthy.
Note:
You need the enable the Remote Server Management on the client servers you want to manage. I took the following steps to enable remote PowerShell on my remote servers:
- Start the “Group Policy Management” console
- Right click on the “Organizational Unit”than you are going to use and click “Create a GPO in this domain, and link it here…”
- In the “New GPO” wizard give the Group Policy “Name” and click “OK”
- Right click on the created Group Policy and click “Edit”
- Navigate to the following path “Computer Configuration\Policies\Administrative Templates\Windows Components\Windows Remote Management(WinRM)\WinRM Service”
- On the “Group Policy Management Editor” screen double click “Allow automatic configuration of listeners”
- Double click on the “Allow automatic configuration of listeners”, “Enable” the policy and set the IPv4/IPv6 “(*)”
- Navigate to the “Computer Configuration\Policies\Windows Settings\Security Settings\System Services”
- Double click “Windows Remote Management (WS-Management)” service and set it for automatic startup.
- Navigate to “Computer Configuration\Policies\Windows Settings\Security Settings\Windows Firewall with advanced Security\Windows Firewall with Advanced Security\Inbound Rules”
- Right click on “Inbound Rules” and click “New Rule”
- On the “New Inbound Rule Wizard” page, on the section “” select “Predefined” and from the pull down menu select “Windows remote Management” and click “Next”
- On the “New Inbound Rule Wizard” page, on the “Predifined Rules” section click “Next”
- On the “New Inbound Rule Wizard” page, on the “Action” section, select “Allow the connection” and click “Finish”
