cannot delete orphan_1 after upgrade (new install) to HPSIM 4.1

[topuli]

after uninstalling hpsim 4.0 and installing hpsim 4.1 which worked fine, i have a problem with my Managementserver (ntwatch1 W2K/SP4). the server shows up in "all system" with ip 127.0.0.1 and i have an orpahn_1 system claiming to be my management server showing up critical with no ip. if i search for the name of my management server the result schows the above mentioned servers(ntwatch1 and orphan_1).
if i try to delete orphan_1 i get the message "The HP Systems Insigtht Manager Server cannot be deleted"

is the connection between this two servers the hostguid ? Will it help if i change it on the managementserver ?

suggestions welcome :)

solved my problem.
i set the key \HLM\Software\Compaq Insight Agent\UseASMBIOSGuid to 0, removed the key hostGUID,restarted the Insight Server Agents and restarted the HPSIM. now i was able to delete the orphan_1 system.
finally i set the key \HLM\Software\Compaq Insight Agent\UseASMBIOSGuid back to 1 restarted both the server agents and the insight manager.
