Running Vista SP2 (Got 7 on my desk, need to find time to upgrade)
Network guy here told me that my machine is broadcasting M-Search packets.
I go OK disable SSDP Discovery and UPnP Device Host services. The network guy says it's still doing it. So I disable my network connection (maybe getting re broadcast by switches), he did not see any SSDP packets, so definitly my machine. I tried rebooting, nothing. I double checked services and both are disabled.
I ran netstat -a -p UDP, to see if there was a binding to port 1900 there isn't.
I am stuck.
