Windows XP includes support for Universal Plug and Play (UnPnP) which allows UnPnP devices to be connected over a network. There are currently limited UnPnP devices available and due to a recent security flaw it may be advisable to disable these services.

Disable Universal Plug and Play Device Host
Open your registry and find the key [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\upnphost]. Set the value of "Start" to "4" to disable the service, or "3" to enable it.

Disable UnPnP Discovery Service
Open your registry and find the key [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SSDPSRV]. Set the value of "Start" to "4" to disable the service, or "3" to enable it.

Restart Windows for the change to take effect.
