Error (2927) - (Unknown error (0x803380e4)) when trying to add a Host or Cluster to System Center Virtual Machine Manager

SYMPTOMS
Adding a Hyper-V Host or Cluster to a System Center Virtual Machine Manager (SCVMM) server generates the following error message:

Error (2927)
A Hardware Management error has occurred trying to contact server <FQDN_Name>. 
(Unknown error (0x803380e4))
 
Recommended Action
Check that WinRM is installed and running on server <FQDN_Name>. For more information use the command "winrm helpmsg hresult".
CAUSE
This can occur when the WinRM Trusthost policy of the SCVMM server is set to blank. The default is TrustedHosts = *. To determine the WinRm Trusthost setting, run the following command on the SCVMM server from an elevated command prompt:

winrm g winrm/config

Here is a snippet from a Host where the WinRM Trusthost policy is set to blank:

DefaultPorts
HTTP = 5985
HTTPS = 5986
TrustedHosts
Service
RootSDDL = O:NSG:BAD:P(A;;GA;;;BA)S:P(AU;FA;GA;;;WD)(AU;SA;GWGX;;;WD)

Here is a snippet from a Host where the WinRM Trusthost policy is set to the default setting:

DefaultPorts
HTTP = 5985
HTTPS = 5986
TrustedHosts = *
Service
RootSDDL = O:NSG:BAD:P(A;;GA;;;BA)(A;;GA;;;S-1-5-21-2210657229-244641257.
RESOLUTION
To resolve this issue, run the following command from an elevated command prompt with Administrative rights on the SCVMM server:

winrm/config/client @{TrustedHosts="*"}
MORE INFORMATION
The issue described above can be created by deploying a Windows Remote Management (WinRM) AD Group Policy and then removing it, leaving the server in an unknown state once the policy is removed.
