Yeah I am in a similar situation.
Traps seem to work just fine, but it screws up my collections since a lot of systems end up as 'unknown'. I also use the daily ID task to find broken agents or servers that are no longer responding to polls.. now the ID task takes 15+ hours and doesn't complete properly, so I can't really tell what servers really have issues since ALL the SNMP servers (Windows) come up as major failures..
I will open a case with HP on this one and post something if I hear back. We're not ready to use WBEM with Windows yet since we have a lot of legacy systems, so that really isn't an option right now. Same goes for agentless, can't do that due to IRSA in case anyone suggests that.
Thanks
