Configuring NIC settings in Windows

Hi Experts,

I'm installing and configuring a new Windows domain. All servers run Windows Server 2012 R2. When i configure the IP settings i always come accross the settings below. Which of these can be turned off? I do not use IPv6. Do i need the QOS packet scheduler? And what about those Link-Layer settings?

The QoS Packet Scheduler is a Windows platform component that is enabled by default on Windows is designed to control the IP traffic for various network services, including Real Time Communications traffic.

This component must be enabled .

Windows preconfigured good defaults for 99.9% of all deployments. The only reason to change any of these from their defaults is if you are in a large datacenter and specialize in this sort of thing.

I disagree with that. You can tweak so many things in registry. Default always sucks if it comes with Microsoft.

Not in their server OS in regards to the networking stack. It is stable, robust, heavily tested and used from small business to fortune 50 companies, and most of those features are tied to APIs that applications expect to be there and working. So unless you *really* like breaking applications and then blaming Microsoft instead of taking responsibility, you should leave them alone.

We have just over 12,000 users and all options are checked. However, if you are not implementing IPv6 you can uncheck that one. You probably won't need Microsoft Network Adapter Multiplexor unless you are using NIC teaming. If you disable the Link-layer protocols you won't see other devices on your network such as media devices, networked gaming consoles, and things like that.

Link Layer Topology Discovery (LLTD) is included in Windows Vista and Windows 7. It is used by their Network Map feature to display a graphical representation of the local area network (LAN) or wireless LAN (WLAN), to which the computer is connected
