Installing Sniffer Portable
Uninstalling the QoS Packet Scheduler Service
The QoS Packet Scheduler service supports the 802.1P traffic prioritization
system, allowing for the implementation of best-effort Quality of Service by
conforming 802.1P equipment. The service is optional on Windows 2000.
However, on Windows XP, the service is automatically bound to each installed
adapter driver. To improve analyzer performance, Network General
recommends that the QoS Packet Scheduler service provided with Windows
XP and Windows 2000 be unbound from any adapters used with Sniffer
Portable.
Sniffer Portable can only check for the existence of the QoS Packet Scheduler
Service during installation. If you rebind the QoS Packet Scheduler Service to
a Sniffer adapter at a later time, that adapter will experience decreased Sniffer
performance.
IMPORTANT: Uninstalling the QoS Packet Scheduler service removes it from
all installed adapters. Unbinding from individual adapters allows you to
preserve the service for use with any non-Sniffer adapters. See
Unbinding the
QoS Packet Scheduler Service from Selected Adapters on page 9.
To uninstall the QOS Packet Scheduler Service:
1 At the conclusion Sniffer Portable installation on Windows XP or
Windows 2000, you are provided the option to completely remove the
QoS (Quality of Service) Packet Scheduler service from the target
system (
Figure 1-1).
2 To uninstall the QoS Packet Scheduler service completely, enable the
Uninstall the QoS Packet Scheduler Service option shown in
Figure
1-1 and click Finish.
