i am writing code for a UPnP device to announce itself. i have no interest in it being able to discover other UPnP devices on the network. i am sending out the following messages (taken from wireshark)

the device will not discover (either on the Win 7 page where i see my other UPnP devices or on Intel's Device Spy for UPnP Technologies -- see update). i have 2 questions. first, are all of these messages necessary? and second, can anyone see why my device would not be discovered?
other info:
my rdd2.xml device description file

and some info from wireshark (a view down one msgs frame list)
+ Frame .....
+ Ethernet II, Src: my device , Dst: 239.255.255.250
+ Internet Protocol, Src Port: ssdp (1900), Dst Port: ssdp (1900)
- Hypertext Transfer Protocol
... msgs from above are here...
UPDATE: i CAN see the device on intel's upnp utilities. that was a mistake writing that. the device was running under a debugger, and once rebooted with no debugger, it DID discover in the utilities. i still cannot see it on windows 7 though? any thoughts?
