Windows uses the following Universal Plug and Play services:
SSDP: Method = M-SEARCH
SSDP: Uniform Resource Identifier = *
SSDP: HTTP Protocol Version = HTTP/1.1
SSDP: Host = 220.127.116.11:1900
SSDP: Search Target = urn:schemas-upnp-org:device:InternetGatewayDevice:1
SSDP: Mandatory Extension = "ssdp:discover"
SSDP: Maximum Wait = 3
This issue may occur if Windows Messenger is using the SSDP discovery process to determine if there is a upstream Internet gateway device. Windows Messenger does not use the built-in Universal Plug and Play services. Windows Messenger formats and sends the SSDP discovery messages.
