Using Content Advisor to control access

The Internet provides unprecedented access to a wide variety of information. Some information, however, may not be suitable for every viewer. For example, you might want to prevent your children from seeing Web sites that contain violent or sexual content.
Content Advisor provides a way to help you control the types of content that your computer can gain access to on the Internet. After you turn on Content Advisor, only rated content that meets or exceeds your criteria can be viewed. You can adjust the settings.
With Content Advisor, you can:
  • Control access to Content Advisor settings. You turn Content Advisor on, and view the settings, through the use of a password. You will need this password to change any Content Advisor settings, so you might want to write it down for future reference.
  • View and adjust the ratings settings to reflect what you think is appropriate content in each of four areas: language, nudity, sex, and violence.
  • Adjust what types of content other people can view, with or without your permission. You can override content settings on a case-by-case basis.
  • Set up a list of Web sites that other people can never view, regardless of how the sites’ contents are rated.
  • Set up a list of Web sites that other people can always view, regardless of how the sites’ contents are rated.
  • View and change the ratings systems and bureaus you use.
Content Advisor is set to the most conservative (least likely to offend) settings when you first turn it on. You can adjust these settings to match your own preferences.
Not all Internet content is rated. If you choose to allow other people to view unrated sites on your computer, some of those sites could contain inappropriate material.

To specify Web sites that others can always or never see

In Control Panel, open Internet Options.
  1. On the Content tab, under Content Advisor, click Enable.
If you've already enabled Content Advisor, click Settings, and then type the supervisor password.
  1. Click the Approved Sites tab, type the Internet address (URL) of a Web site, and then choose whether you want others to always or never have access to this site.
Repeat this process for each Web site that you want to set access for.
Note
  • You can also open Internet Options by clicking the Tools menu in Internet Explorer, and then clicking Internet Options.

Attaining fast speeds with a 56 kbps modem

A modem connection must fulfill three requirements to support a 56 kilobits per second (Kbps) (also called V.90) connection:
  • The host server must use a digital connection to the network. Your Internet service provider can tell you if they support 56 Kbps service.
  • Both ends of the connection must support the same protocol, the V.90 standard or either of its predecessors, K56flex, or 3COM/USR X2. For example, if your Internet service provider has a V.90 device, your modem must support the V.90 protocol.
  • There can only be one analog connection between your modem and the host computer. The phone line in most homes is an analog line.
If a connection does not meet these requirements, a modem falls back to the fastest protocol that works for the connection. For example, a 56 Kbps V.90 modem falls back to the 33.6 Kbps V.34 protocol if it cannot make a V.90 connection. Even if your connection fulfills these requirements, other factors may reduce either the transmission speed or the number of times that you successfully obtain the highest speed connection. For example, old lines, or lines that are subject to interference, might reduce transmission speeds. Maximum throughput speeds of 26 Kbps are not unusual in these cases.
Devices to improve the quality of your telephone service may also hamper 56 Kbps V.90 modem connections. Load coils found on long wire lengths to improve voice quality do not usually prevent V.90 connections, but can reduce the speed. Digital pads, which balance the volume of voice calls, usually do not prevent V.90 connections, but they can reduce the speed. Analog pads prevent V.90 connections, because they convert the digital data to analog to balance the volume, and then back to digital data. This inserts an additional analog section in the line.
In practice, the 56 Kbps speed supported by the V.90 and other protocols is unattainable. U.S. government regulations that currently safeguard public phone systems limit transmission speeds to 53 Kbps. Phone-line noise and other limitations of phone systems usually keep average transmissions in the 40 to 50 Kbps range.

Hardware requirements for network connections

Depending on your configuration, you may need some or all of the following hardware:
  • Network adapter with a Network Driver Interface Specification (NDIS) driver for LAN connectivity
  • One or more compatible modems and an available COM port
  • A 28.8k or 56k modem or ISDN adapter (if you are using an ISDN line)
  • DSL modem. If this is an external DSL modem it typically is connected to an Ethernet network adapter.
  • Cable Modem. If this is an external cable modem it typically is connected to an Ethernet network adapter.
  • X.25 card or PAD (if you are using X.25)
  • Analog telephone line
  • If your computer is set up for incoming connections, a multiport adapter may improve performance for multiple connections.
To find hardware that is supported by Windows operating systems, visit the Windows Catalog on the Microsoft Web site.
For information about configuring a connection, see To configure a connection.

Network configurations overview

There are two ways to connect your home or small office network to the Internet. You can use a residential gateway, or use Internet Connection Sharing (ICS).

Residential gateway

A residential gateway is a hardware device that connects a home or small office network to the Internet. This device is sometimes called an Internet gateway device, a router, a base station, or an access point. The residential gateway lets you share a DSL or cable modem Internet connection with all of the computers on your network.
The advantages of using a residential gateway are:
  • The gateway looks like a computer on the Internet, which hides the real computers on your network when you are on the Internet.
  • The gateway shares one Internet connection with all the computers on your network.
  • One computer does not have to be turned on all the time to provide Internet connectivity.
  • You can use the UPnP framework to control your Internet connection from anywhere in your home or small office.
The disadvantage of using a residential gateway is that the hardware is more expensive.

Using Internet Connection Sharing

If you do not want to buy a residential gateway device, you can use a configuration like this illustration of an Ethernet network. You can create a home or small office network using this configuration with a home phone line network adapter (HPNA) or wireless network adapters. In this configuration, one computer is the ICS host computer and shares its Internet connection. Internet communications to and from the computers in your network go through the ICS host computer.
The advantage of this configuration is that sharing one Internet connection with all the computers on your network can cut the cost of connecting to the Internet.
The disadvantage of this configuration is that the host computer must be turned on at all times so that the other computers can access the Internet.

To add a new user to the computer

When you add a user to your computer, you are allowing that individual to have access to files and programs on your computer.
The steps to perform this task differ depending on whether your computer is a member of a network domain or is part of a workgroup (or is a stand-alone computer).
My computer is on a domain
You must be logged on as an administrator or a member of the Administrators group in order to complete this procedure. If your computer is connected to a network, network policy settings might also prevent you from completing this procedure.
·        Open User Accounts in Control Panel.
·        On the Users tab, click Add.
·        Follow the instructions on the screen to add a new user.
Notes
·         Add New User gives an existing domain user permission to use the computer.
·         You can only add existing domain users by using User Accounts. To add a new local user, on the advanced tab, click the advanced button. In Local Users and Groups, click Users, and then on the Action menu, click New User.
·         You should not add a new user to the Administrators group unless the user will perform only administrative tasks. For more information, click Related Topics.

My computer is not on a domain
You must have a computer administrator account on the computer to add a new user to the computer.
·        Open User Accounts in Control Panel.
·        Click Create a new account.
·        Type a name for the new user account, and then click Next.
·        Click Computer administrator or Limited, depending on the type of account you want to assign to the new user, and then click Create Account.
