HTTP in the Event Log on XPSP2


Thoose who are really looking might have found the following event in your event log:

Reservation for namespace identified by URL prefix http://*:2869/ was successfully added.

This is just UPNP reserving it’s port and namespace in http.sys.

    What about UDP and Multicasted traffic? Doesn’t UPnP use HTTP via UDP and multicasted Discovery notifications? Does UPnP use it’s own protocol stack for these functionality?

    Second questions: the url http://*:2869 is a weak reservation; if some application uses a stronger url for the binding, UPNP will never receive any packets?

    Yes, I believe that it is using it’s own protocol stack for thoose parts.

    The second part sounds correct as well.
