I need to campus-wide disable the Microsoft LLDP Protocol Driver using Group Policy / SCCM / or any other means of centralized management, because I've written my own LLDP broadcast service I plan on using instead of the crippled MS implementation. I tried googling but wasn't able to come up with a working solution. EDIT: I took two registry snapshots and compared them, the three keys that change when the checkbox is toggled are located under HKLM SYSTEM CurrentControlSet Services MsLldp Linkage The keys are Bind / Route / Export The problem is when these keys are deleted / emptied, the checkbox turns itself back on.

The LLTD protocol enables applications to quickly discover devices at the data-link layer, and it enables a central, graphical view of everything that is connected to the network. Any device that implements LLTD appears on the Network Map with a rich icon that represents the device, allowing users one-click access to the device’s Web user interface (UI). LLTD provides the added benefit of enabling quality media streaming experiences, even on networks with limited bandwidth. Devices that provide audio or video playback or that are bandwidth sensitive can implement the QoS Extension portions of the protocol to ensure that they receive prioritized streams and that changes in available bandwidth have little or no impact on the user experience. Specification link: Network Topology and QoS Extensions: LLTD The specification for Link Layer Topology Discovery describes how the LLTD protocol operates over wired (802.3 Ethernet) and wireless (802.11) media. As the protocol name suggests, LLTD enables device discovery via the data-link layer (Layer 2) and determines the topology of a network. Driver Dell Floppy Disk Drive Module.
