	// The CleanUpEvictedNode method removes all persistent artifacts that exist on the
	// server after it is evicted from a cluster.
	//
	// This method is idempotent. After it is invoked, the target server can no longer be
	// a server for the Failover Cluster: Cluster Management Remote Protocol (ClusAPI) ([MS-CMRP])
	// until the server is reconfigured as a member of a cluster by using implementation-specific
	// methods between servers.
	//
	// Return Values: A signed 32-bit value that indicates return status. If the method
	// returns a negative value, it has failed. Zero or positive values indicate success,
	// with the lower 16 bits in positive nonzero values containing warnings or flags defined
	// in the method implementation. For more information about Win32 error codes and HRESULT
	// values, see [MS-ERREF] sections 2.2 and 2.1.
