Description

The Uninstall-HgsServer cmdlet removes a local node from a Host Guardian Service (HGS).

This cmdlet makes the following configuration changes in order to remove the HGS configuration from the additional HGS node:

  • Unregisters the Attestation Service web application with the IIS service.
  • Unregisters the Key Protection Service web application with the IIS service.
  • Disables Just Enough Administration on the local node.
  • Removes the local node from the existing failover cluster.
  • Removes the local node from being a domain controller.

This cmdlet makes the following configuration changes in order to remove the HGS configuration from the last HGS node:

  • Unregisters the Attestation Service web application with the IIS service.
  • Unregisters the Key Protection Service web application with the IIS service.
  • Removes the distributed network name (DNN) resource corresponding to the HGS name.
  • Disables Just Enough Administration on the local node.
  • Destroys the cluster on the local node.
  • Removes the local node from being a domain controller and removes the HGS domain.

For more information about the scenario terms, see Security and Assurance.

Examples

Example 1: Remove the node from HGS

PS C:\> $Cred = Get-Credential
PS C:\> Uninstall-HgsServer -HgsDomainCredential $cred -LocalAdministratorPassword $secureString

This example removes the node from an existing HGS setup. If the second command removes the final node, then it also destroys the cluster.
