Multicast support is enabled by default.
In the Show Binding For drop down list, select All Protocols . The bindings for all installed networking protocols can be displayed and modified in this dialog box. Note that WLBS Driver appears in the list of protocols. For each protocol, you can see the network interface cards, also known as adapters, to which each protocol is bound. WLBS registers itself with Windows NT as both a protocol and as a virtual network adapter.
