Need to monitor all windows services in LM

You should be able to clone the existing WinService- DataSource (which is what the wizard uses) and implement an AD WMI method to pull ALL the services then use the filter to remove disabled services and special cases. You may also want to not delete any instances immediately because once a instance gets deleted, you lose all historical/performance data for that service. You can still delete it manually if it's really gone or set to 30 days before delete.
