1. Open Run box, key gpedit.msc to open Local Group Policy Editor.

2. Navigate to Computer Configuration >> Administrative Templates >> System >> Credentials Delegation >> Encryption Oracle Remediation. Then select  Enable >> Vulnerable >> OK.

3. Finally, open CMD (run as Administrator), run the command: gpupdate /force
to update the policy immediately.

Make sure the firewall of your computer doesn't lock this new port.
