Internet connection idiosyncrasies!
Began spontaneously two weeks ago. I was told by my ISP that it was probably my Internet Explorer 6, which had failed.
I don't believe that Internet Explorer 6 failing and then reinstalling has any affect on proxy, this based on your quote below, but is also contingent on just how your system is wired either at home or to the Web or both:
"But everytime, I boot up, and try to reach a web site, ( I am connected to the internet) I simply have to go to Internet Options (connections section) and clear the Proxy setting in the Connections Tab Section, in order to even reach my own start page."
1. "How to Connect to the Internet in Windows 95 and Windows 98 (Q138789)."
2. First, Internet requests from clients sent to a Internet Connection Sharing (ICS) host may not automatically dial a connection to the Internet if the ICS host is not configured to dial automatically and the user name and password information is missing. If it is not configured properly, the ICS host receives the Internet request but does not have the means to establish the connection without user intervention, [Q236445]. Also, please review "Description of How ICS Appears in Network Properties (Q236465)" and "How to Troubleshoot Internet Connection Sharing Problems (Q238135)."
3. Second, when using an asymmetric digital subscriber line (ADSL) or a digital subscriber line (DSL) to connect to the Internet and the Dial whenever a network connection is not present setting in Internet Explorer 5 is enabled, you may not be able to gain access to Internet sites. In addition, the Connect To dialog box may be displayed when starting Internet Explorer, [Q240808].
4. Third, in the Windows Millennium edition when changing the options under Connection settings in the Internet Options window, from Never dial a connection to Always dial my default connection, the setting seems to change but when trying to access the Internet, or to view the actual connection setting, it reverts back to Never dial a connection. This issue occurs when Internet Call Waiting for PC by Bell Canada has been installed, [Q275317].
5. The article [Q169514] states the Internet Connection Wizard is included in every copy of IE and a fully automated process that takes you through three important steps to set up your connection to the Internet. After completing each step, the wizard saves Internet connection information to your computer so that you will have the proper configuration for accessing the Internet in the future.
6. The article [Q272282] states that when you click the Connections tab the Dial-up settings options may be unavailable (dimmed) and you are therefore unable to select any of the listed connections. This behavior can occur regardless of the check boxes selected under Local Area Network (LAN) settings, whether or not the Automatically detect settings check box is selected, whether or not a network adapter is installed, and occurs if the EnableAutodial registry key is disabled, missing, or damaged.
Note: The symptoms caused by the above anomaly is that IE will ignore any options as stated and attempt to connect to a proxy server when you initialize a dial-up connection. In addition a proxy server may be the proxy server that you last used to access the Internet. (The article Q220902 referenced below) states that IE 5.x may appear to stop responding (hang) when opened but the animated globe in the upper-right corner of the browser window may continue to spin and you may receive a "Detecting proxy settings..." message in the status bar which can occur when trying to locate a proxy server:
a. Proxy Auto-Discovery is enabled by default and this feature may make it appear as if IE is not responding.
b. Your computer is on a network that includes a Dynamic Host Configuration Protocol (DHCP) server that does not include Web Proxy Auto-Discovery (WPAD) information in its DHCP packets. This may prevent Internet Explorer from locating a proxy server.
7. The article [Q320162] states that after you connect to the Internet and then try to start Internet Explorer, the home page may appear to stop responding for up to several minutes, or not open at all. Or, the browser itself may stop responding and must be restarted. This behavior may occur if certain versions of the Msbb.exe file (a component of the n-CASE program from 180Solutions, Inc.) is running in conjunction with certain versions of the New.net software.
8. "LSP-Fix" is a free utility that may be downloaded to repair certain problems associated with Internet software when you can no longer access Web sites due to bugs in the LSP software or deletion of software. LSP-Fix repairs the Winsock LSP chain by removing the entries left behind when LSP software is removed by hand (or when errors in the software itself break the LSP chain), and removing any gaps in the chain.

1. Dial-Up Networking can bind up to three "protocols" (Click to see an example screenshot). NetBEUI, IPX/SPX, and TCP/IP are used by default for a Dial-Up Networking connection.
a. However, the fact that these protocols are used by default and setup by a Dial-Up Networking connection, it does not necessarily mean that these protocols are available until installed correctly and even if installed correctly, they may be entirely unncessary and cause program initiation delay when a connection service cannot carry out instructions which are either invalid or simply unavailable -- but must go through the process simply because it is being instructed to. Therefore, a browser cannot initiate until all instructions have been completed whether necessary or not.
b. Each protocol must be installed from the Control Panel and then bound to the Dial-Up Networking adapter. If any two of these three are unnecessary for a particular operation, they should not be used "IMO".
c. When a delayed connection occurs:
(1) Click Start, Programs, Accessories, Communications, and then click Dial-Up Networking.
(2) Right-click the connection icon, and then click Properties.
Note: If your provider requires a terminal window to log on, click Configure, Options tab and make sure the Bring up terminal window after dialing check box is selected, and then click OK.
(3) Click the Server Type tab and make sure Type of Dial-Up Server is set to PPP.
Hint: You can decrease the time required to connect by making sure that the following options are not selected:
Log On To Network
2. If connecting to the Web using a Dial-Up Networking connection:
a. Click Start, Settings, Control Panel, and then double-click Internet.
b. Click the Connection tab, click the appropriate connection, and then click Settings.
c. Click the Automatically detect settings check box to clear it, and then click OK twice to Exit.
Note: Automatic detection of browser settings is based on Web Proxy AutoDiscovery (WPAD) and is supported by both Dynamic Host Configuration Protocol (DHCP) and Domain Name System (DNS). With the appropriate settings and if used, DHCP servers which support the DHCPINFORM message and DNS servers, they can automatically detect and configure a browser's proxy settings.

1. The article "Troubleshooting Browsing Error Messages in Microsoft Internet Explorer" describes the steps you can use to troubleshoot the following error messages:
a. The Page Cannot Be Displayed.
b. Internet Explorer cannot open the Internet site Web address. A connection with the server could not be established.
c. The page you are looking for is currently unavailable. The Web site might be experiencing technical difficulties, or you may need to adjust your browser settings.
d. Cannot find server or DNS Error.
e. An internal error occurred in Windows Internet extensions.
2. "The page cannot be displayed" is a link to articles published by MS.
