HCW8100, HCW8084, or HCW8083 error when you run the Hybrid Configuration Wizard
Original KB number: 3185373
The Hybrid Configuration Wizard that's included in the Exchange Management Console in Microsoft Exchange Server 2010 is no longer supported. Therefore, you should no longer use the old Hybrid Configuration Wizard. Instead, use the Microsoft 365 Hybrid Configuration Wizard that's available at https://aka.ms/HybridWizard. For more information, see Microsoft 365 Hybrid Configuration wizard for Exchange 2010.
When you run the Hybrid Configuration Wizard, you receive one of the following error messages:
HCW8100 = The connection to the Remote PowerShell server was disconnected. Please try again.
HCW8084 = The connection to the Remote PowerShell server was disconnected. Please try again.
HCW8083 = WinRM cannot complete the operation. Verify that the specified computer name is valid, that the computer is accessible over the network, and that a firewall exception for the WinRM service is enabled and allows access from this computer.
This is usually a transient issue that is caused by a network connection or device.
Close the Hybrid Configuration Wizard, and then run it again. You can download the wizard from https://aka.ms/HybridWizard. Rerunning the wizard starts a new connection and should resolve this issue.
