Yes you are right, you can request more M-SEARCH from the UPnP Tester developed by us while this process is going on my upnp event listener is > registering and wants to know the status. > And maybe thats the cause for the "lost" stati? In fact, I asked you in my previous e-mail if you can receive the notification on the "exporting" computer and if you have a network connecting only the two computers. In general the problem is that the event notification is transported by means of UDP packet, hence the OS may discard it if it receives too many packet at the same time. The "Too many packets" event be caused by the following reason: anytime the UPnP Driver receive a packet it have to process it in the same thread before reading the next packet, hence the OS buffer the other request, but the buffer may not be enough if the number of packet is big. At the end, my opinion the way to check where is the problem is: 1 - Check if you can receive event on the exporting computer 2 - If you receive packet try to test the overall architecture with less sensor Ciao, Stefano "Kismet" Lenzi --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
