SUMMARY
This article discusses how to configure Microsoft Windows Small Business Server 2003 for Internet access. This information applies to the most common configurations that use either one network adapter or two network adapters. The article provides configuration information for TCP/IP connectivity and for name resolution for both the local network and for the Internet. Correctly configured settings provide a stable environment for your Active Directory directory service domain.

This article does not discuss e-mail configurations, Web site configurations, or firewall packet filters.

The information in this article may be useful to help troubleshoot any one of the following situations:
 * Load times are slow during the &quot;Configuring Network Connections&quot; phase during system startup.
 * Users cannot access the Internet.
 * Users cannot log on to the domain.
 * The Exchange server cannot send e-mail messages, receive e-mail messages, or both.
 * Event ID 5775 DNS deregistration errors are generated when a domain controller cannot unregister an individual resource record.

Windows Small Business Server 2003 was designed to be configured by using the Configure E-mail and Internet Connection Wizard. This article describes some of the configurations that are set by the wizard. For most settings, use the wizard instead of manually configuring your network. However, you may have to manually configure some settings in the scenarios that are not supported by the wizard.

The Configure E-mail and Internet Connection Wizard
The Configure E-mail and Internet Connection Wizard (sometimes known as CEICW) is designed to correctly configure settings for your network, your firewall, your Web site, and your e-mail services that are used when you connect your Windows Small Business Server 2003-based computer to the Internet. You can use the Configure E-mail and Internet Connection Wizard to configure the settings that are discussed in the &quot;Configurations&quot; section later in this article. You can use the wizard to change from one network configuration to another. Additionally, if the network configuration of your server becomes corrupted or changed in any way, you can restore the configuration by running the Configure E-mail and Internet Connection Wizard again.

Use the Configure E-mail and Internet Connection Wizard to configure the following connection types:
 * Modem
 * Direct broadband
 * Broadband that uses a local router device with an Internet Protocol (IP) address
 * Broadband that requires a user name and a password and uses Point to Point Protocol over Ethernet (PPPoE) connections

Note Connection types other than these four may require manual configuration.

Firewall protection options
Firewalls are very important to help keep your server and network secure. There are four scenarios for configuring firewall protection with Windows Small Business Server 2003:  Scenario 1: Use a router or a firewall hardware device, or use firewall software that is external to the server.

There are many different hardware routing solutions that also provide firewall functionality. There are also varying degrees of firewall protection with these devices. Make sure that you choose a device that meets your security requirements. Many of these devices support UPnP architecture. UPnP-certified routers are supported by Windows Small Business Server 2003 and can be configured by the Configure E-mail and Internet Connection Wizard. Additionally, there is firewall software, such as Microsoft Internet Security and Acceleration Server (ISA), that can be run on a separate computer. Firewall software that is run on a separate computer or firewall hardware that is not UPnP certified must be configured manually. Scenario 2: Use the Routing and Remote Access Basic Firewall functionality that is included with Windows Small Business Server 2003.

Routing and Remote Access Basic Firewall is used by Windows Small Business Server 2003 to offer basic firewall protection. For additional information, visit the following Microsoft Web site:

http://technet2.microsoft.com/WindowsServer/en/library/7c9a082b-0c5c-49d1-a1a8-5bfccc0eeb5c1033.mspx?mfr=true

When you run the Configure E-mail and Internet Connection Wizard, click the Enable Firewall option. The Routing and Remote Access Basic Firewall is configured and enabled if ISA is not installed and if any one of the following conditions is true:  You are using a dial-up connection to the Internet. You are using a direct broadband connection to the Internet. (This option requires that your server has two network adapters.) You are using a direct broadband connection that requires a user name and a password.  Scenario 3: Install and then run firewall software, such as ISA, on the server.

Windows Small Business Server 2003 is fully compatible with Microsoft ISA Server 2000. Running the Configure E-mail and Internet Connection Wizard makes all configurations to ISA for server connectivity. Non-Microsoft firewall software may create conflicts with server operations if the software is not configured correctly.</li> Scenario 4: Use a combination of scenario 1 with either scenario 2 or scenario 3.

When it is used with a UPnP-certified router, the Configure E-mail and Internet Connection Wizard can configure both the server and the router.</li></ul>

Internet connection types
The following list contains the six most common connection types. The table after this list contains configuration information. You can use the Configure E-mail and Internet Connection Wizard options to configure these connection types:
 * Broadband - Examples of broadband connections include cable modems, DSL, or any variant of T1.
 * Modem - This type can be either plain old telephone service (POTS) that you connect to by using a modem, or it can be Integrated Services Digital Network (ISDN) that you connect to by using a terminal. The modem or terminal must be connected to the server through a Common Object File Format (COM) port or through a hardware card that is installed in the server.

If you connect to POTS or ISDN by using a network router, treat that connection as a broadband connection.
 * Router - A device that maintains its own IP address. (It may or may not offer firewall protection.) If you have a router that supports UPnP, the Configure E-mail and Internet Connection Wizard can configure it for you. However, you can always choose to manually configure your router.
 * PPPoE - Point to Point Protocol over Ethernet. This protocol is used when your Internet service provider (ISP) requires a logon account and a password for the connection. If want to use a router, verify that the router provides PPPoE credentials to your ISP, and then treat your connection as a local router device with an IP address.

Note PPPoE does not work through a router.
 * Network adapters - This is the number of network adapters on the server that will be connected to the Internet and to the local area network. A two-network-adapter configuration connects one adapter to the local area network and connects the other to the Internet. A one-network adapter configuration connects a single network adapter to the local area network. A router that is connected to the local area network or to a modem that is connected to a server provides connection to the Internet.
 *  Configure E-mail and Internet Connection Wizard Configurations - The following table lists the options that are available to help you use the Configure E-mail and Internet Connection Wizard. Numbers 1 through 9 in the Configure E-mail and Internet Connection Wizard Option column of the table refer to instructions that are listed in the Configure E-mail and Internet Connection Wizard Options section of this article. Configuration settings for the firewall packet, for Web sites, and for e-mail are not covered in this article. Complete the Configure E-mail and Internet Connection Wizard according to your business requirements.
