SECURITY ENHANCEMENTS
=====================
Microsoft Internet Explorer 3.02 contains many security enhancements 
that make opening and downloading pages from the Web safer than 
ever before.


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:

                                  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 "<local>".

   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.
