Description and service settings under Windows XP

QoS RSVP:
Provides the network signalisation and installation functionality to control the local traffic for QoS programs and control services.
QoS RSVP (Quality of Service Resource ReServation Protocol) is used to reserve the network bandwidth when QoS services are active. Leave this service on automatic. The quantity of the Windows bandwidth is 20% and it is highly recommended to change this!
Click on Start, Run and type “gpedit.msc”. In the left column, select “Computer Configuration”, “Administration Models”, “Network” and select “QoS Packet planner”.

In the right column, double click on the “limit reserved bandwidth” options. Click on “Activate” and change the number to what you want. If you don’t have any QoS applications then you can change this number to 0 to conserve as much bandwidth as possible.

Routing and Remote Access:
Used by companies to perform their local area network routing.
For security reasons leave this service on disabled. If you want an external person to have access to your PC, or if you want to use ICS then leave this on automatic.

COM Service and CD IMAPI Burning:
Manages the CD writing with its IMAPI interface (Image Mastering Applications Programming Interface). If you want to write CD’s from XP applications then leave this service on automatic. If you don’t have a CD writer or if you use another application like Nero then you can change this to manual without affecting your writing processes.

COM+ System events:
Looks after your systems notification system (SENS, System Event Notification Service) which is an automatic distribution of your subscribed COM components (Compact Object Model). Manages the automatic COM components events that have object subscriptions. Leave this on automatic.

Encryption Service:
Is three management systems: The search and catalogue service, which confirms Windows files are signed; The protect root service which adds and removes root authorisation certificates and the service key that is provided with the help of a subscription for this computer for certificates.
Confirmation of Windows file signatures, protection of the root system and certificate management. This service must be left of automatic for your PC to have the best security possible.

Intelligent transfer service:
Uses the inactive network bandwidth to transfer files.
For most users this function is rarely used and it is recommended to leave it on manual. Those that transfer a lot of files over the network will benefit from this function and should leave it on automatic.
