This occurs because the appropriate drivers have not been installed on the ProLiant 100-Series G5 server running Windows Server 2003 or Windows Server 2008. The Unknown devices should be labeled as "HP Null Management Controller" and "Microsoft Generic IPMI Compliant Devices."
Any ProLiant 100-Series G5 server running Windows Server 2003 or Windows Server 2008.
The Unknown devices displayed in the Other devices section can be safely ignored if there is not a plan to use Windows Management Instrumentation (WMI). One of the Unknown devices should be labeled as "Microsoft Generic IPMI Compliant Device," which is used for WMI.
