In my list of devices, I have purged all devices on a particular subnet. If I do an auto discovery, or a manual discovery, the devices cannot be found. But, if I ping the device, it can be reached. If I manually add a device on that subnet, The Dude will auto discover services for that device. Furthermore, if I sniff packets, I see that the devices are communicating with SNMP data being properly passed and read. But, the devices are not added to The Dude

HELP.

I am guessing that I have lingering DB records that are messed up. Can I purge them somehow?
