SSDP Discovery

The SSDP Discovery (SSDPSRV) service discovers networks devices and services that use the simple service discovery protocol (SSDP), such as Universal Plug and Play (UPnP) devices. For example, the UPnP Device Host service uses SSDP to locate and identify UPnP-certified network devices and service. The SSDP Discovery service also announces SSDP devices and services that are running on the local computer.

The service is started only when the computer attempts to locate and configure UPnP-certified devices. If you disable this service, the computer is cannot find UPnP-certified devices on the network and the UPnP Device Host service cannot find and interact with UPnP-certified devices.
