USING THE INTERNET CONNECTION WIZARD ==================================== Connecting to the Internet is quick and easy using the Internet Connection wizard. The Internet Connection wizard helps you set up your computer to communicate with the Internet, helps you sign up for an account with an Internet service provider, and sets up the Internet software you need to use your account. When you've completed the wizard, you are ready to explore the Internet. To start the wizard for the first time, double-click The Internet icon on your desktop. If you need to start the wizard again at a later time, click the Start menu, point to Programs, point to Accessories, point to Internet Tools, and then click Get On The Internet. NOTE: If you install this version of Internet Explorer and then install an earlier version of Internet Explorer (for example, Internet Explorer 2.0), the Internet Connection wizard will not work. The wizard connects you to the Microsoft Internet Referral Service. This service provides you with a list of the service providers available in your area. To determine which service providers are available, the wizard sends the following information to the Internet Referral Service: Field Description ----- ----------- Country Id The country from which you are dialing Area/City Code Your area or city code Exchange Code(US only) Your local exchange code (the first three digits of your local phone number) Language Id The language of the Windows software currently installed on your computer Operating Platform The operating system installed on your computer Operating Platform Version The version of your operating system Processor Arch The processor architecture of your computer if it runs Windows NT (for example, x86, Alpha, MIPS, or PowerPC) Product Code The software product you are using to connect to the Internet Referral Service Promotional Code The promotional offer (if any) in which you are participating Manufacturer Code The manufacturer of your computer, if the manufacturer includes any special offers Signup Version The version of the Internet Connec- tion wizard your computer is running INSTALLING PC CARD (PCMCIA) MODEMS ================================== If you are using a PC card (PCMCIA) modem for your Dial-up Networking connection to the Internet and have not yet installed the modem, you may have to enable Windows 95 PC card socket support before running the Internet Setup wizard. To enable PCMCIA socket support: 1. Click the Start button, point to Settings, and then click Control Panel. 2. Double-click the PC Card (PCMCIA) icon to start the PC Card wizard, and then follow the instructions on your screen. NOTE: If you can't find the PC Card icon, you may need to install the PC card (PCMCIA) drivers. To do this, double-click the Add New Hardware icon, click No, click PCMCIA Support from the list of hardware items, and then follow the instructions on your screen. USING A LOCAL AREA NETWORK PROXY OR FIREWALL ============================================ If you want to gain access to the Internet by using your local area network (LAN) through a proxy or firewall (typically used to protect your LAN from being accessed by others on the Internet), follow these steps: 1. Install the TCP/IP protocol on your computer by carrying out the following steps. This is the protocol your computer will use to connect to the Internet. 1. In Control Panel, double-click the Network icon. 2. Click Add, click Protocol, and then click Add. 3. In the Manufacturers area, click Microsoft. 4. In the Network Protocols area, click TCP/IP, and then click OK. 5. In the list of components, click your network adapter, and then click Properties. 6. Click the Bindings tab, and then select the check box next to TCP/IP. NOTE: Currently, the Internet Connection Wizard does not automatically install the TCP/IP protocol for LAN setups. 2. Run the Internet Connection Wizard. To run the wizard, click the Start menu, and then click Help. In the Index, double-click "Internet," and then select "Quick and easy way to set up an Internet connection." 3. Choose the Manual setup option, and then follow the instructions on your screen. 4. When you are prompted to specify "How to Connect," click Connect Using My Local Area Network. 5. When you are prompted to do so, make sure that you select the Use Proxy Server check box. 6. Type the http server address and the port number for the computer you want to use as the proxy server in the Proxy Server box. The following is an example of a proxy server address and port number: http://myproxy.mycompany.com:80 In the Bypass Proxy On box, type the names of the computers, domains, and ports on the Internet that, when accessed, will not go through the proxy server. Separate each item you type with a comma. If you want to bypass the proxy when accessing all local computers (computers on your LAN), type "". If you do not know what to type in the Proxy Server, or Bypass Proxy On boxes, see your network administrator. For Help on these items, click the ? in the title bar, and then click the item. Using the New Auto-Proxy Feature -------------------------------- Internet Explorer 3.02 contains a new feature named Auto-Proxy. To learn how to use this feature, see the Web page at the following address: http://www.microsoft.com/ie/ieak/auto.htm. USING INTERNET EXPLORER WITH VIRTUAL MEMORY =========================================== Internet Explorer requires you to use virtual memory. Otherwise, Internet Explorer will not run properly. To make sure you are using virtual memory: 1. Click the Start button, then point to Settings, and then click Control Panel. 2. Double-click the System icon, and then click the Performance tab. 3. Click the Virtual Memory button. 4. If you are specifying your own virtual memory settings, make sure the Disable Virtual Memory box is unchecked. If this box is checked, then you are not using virtual memory and Internet Explorer won't run. TIP: It is recommended that you let Windows manage virtual memory for you by selecting the Let Windows Manage My Virtual Memory Settings option. USING CITRIX WINFRAME WEB CLIENT ================================ With the WinFrame Web Client, you can run Windows programs remotely over the Internet and the intranet. Because the WinFrame Web Client is installed on your computer, you can run some sample Windows programs over the Internet from the Citrix Web site at the following address: http://www.citrix.com/hotspot.htm To run these programs over the Internet, you need an Internet account that does not use a proxy server. After you connect to the site listed above, just click the program icons on the Web page to launch a program. The demo room designed by Citrix is in English. Saving a File to Your Desktop ----------------------------- If the Windows-based program that you run allows you to save a document, you can save the file to your desktop by carrying out the following steps: 1. Click the File menu, and then click Save As. 2. Click Network, and then connect to your client by clicking the network connection named Client. 3. Choose your drive, assign a network drive, and then click OK. 4. Click Save. The WinFrame server can be configured so that it doesn't allow users to save to the client computer. Also, some programs might not allow you to create a network connection with your computer. Printing to the User's Printer ------------------------------ The WinFrame Web Client has the client printing feature turned off. In an intranet network, the WinFrame server can be configured to share out the network printer to the user, and the user can print to this printer if the Server Administrator allows the user to access it. CACHE STRUCTURE =============== With the release of Internet Explorer and the Internet SDK, it is expected that many different programs will take advantage of the caching support provided. This means that there could be thousands of URLs downloaded and kept in the cache. Having thousands of URLs cached into a single directory causes performance to degrade on computers running Windows 95, which use the FAT file system. The FAT file system might take a long time to look up a file in a directory when the directory contains thousands of entries. There are two primary reasons: - There is a linear search algorithm in FAT to look up a directory entry. - The in-memory structure of the directory entry caching used by FAT does not work by directory but by individual file, causing it to access the disk more often. This is the main reason there are multiple directories in the cache. Internet Explorer directs each URL into one of the multiple directories, where the downloaded data is kept in the form of a file. An index entry is created in the index file(s) in that directory to speed up access to these URLs. KNOWN ISSUES ============ Installing on a Dual-Boot Computer ---------------------------------- If you have installed multiple instances of Internet Explorer on different platforms on the same computer, you must upgrade the installations on both platforms if you upgrade either one. You need to do this only if the multiple installations are on the same drive. This problem does not occur if you have installed different versions of Internet Explorer on different drives or partitions. Running the Internet Explorer 3.0 Script Debugger ------------------------------------------------- The script debugger does not work under Internet Explorer 3.02. If you have the Internet Explorer 3.0 script debugger installed, do not upgrade to Internet Explorer 3.02 unless you first uninstall the script debugger. If you already have Internet Explorer 3.02 installed, do not install the script debugger. Configuring Your Default Mail Program -------------------------------------- When you install Internet Explorer 3.02, Internet Mail and News is set up to be the default mail program used when you are browsing the Internet. However, the setting in Internet Properties erroneously displays the name of your previous mail program. To work around this problem, carry out the following steps: 1. Right-click The Internet icon on your desktop, and then click Properties. 2. Click the Programs tab. 3. In the Mail And News area, change the Mail program to any other program, and then click Apply. 4. In the Mail and News area, change the Mail program back to Internet Mail, and then click Apply again.
