Troubleshooting Usage and Performance

This section covers troubleshooting networking configuration, graphics, cpu, remote
audio, and remote USB.
Troubleshooting Network Configuration

switches that are present on the local network. The negotiated speed can
vary from 10Mb half duplex (HD) to 10Gb full duplex (FD). Ideally most
modern NICs and switches negotiate the highest possible speed available. In
the real world, unless the network was carefully designed for maximum
throughput, the settings in the NICs and switches will auto-negotiate to a
sub-optimal speed. By understanding this effect, the NIC and switches can be
configured properly such that the highest speed possible is achieved. If the
NICs and switches are configured to auto-negotiate properly, you can leave
the settings to auto-negotiate. If you want to force the network to operate at
a particular speed, the settings in the NICs and switches can be hard-coded.
You must be careful with these settings though. If they are not setup such
that the NICs and switch settings complement each other, the network will
operate with poor performance.
Configuring the NIC on Windows

You change the link speed and duplex on Microsoft Windows by
opening the Device Manager. Open up the Control Panel -> System
-> Hardware Tab -> Device Manager button. Once the Device
Manager dialog is open, click the + next to Network adapters. Then,
right-click on the adapter that you want to change and select
Properties. Click the Advanced tab. Each network adapter has its own
properties/settings that can be changed. The property that affects the
link speed and duplex is usually named "Link Speed & Duplex". Click
that property. If you decide that Auto-negotiation is what you want,
pick the Auto Detect entry in the "Value" box. If you want to hard-
code the speed and duplex, always choose the fastest link your
network can support and always choose the
