Hello.
How come I cannot connect to https://github.com/ in 2 different
machines' Windows XP Pro SP3's IE8 web browsers? They show:
"Internet Explorer cannot display the webpage

???The Domain Name Server (DNS) does not have a listing for the website's domain.
???There might be a typing error in the address.
???If this is an HTTPS (secure) address, click Tools, click Internet Options, click Advanced, and check to be sure the SSL and TLS protocols
are enabled under the security section.

Is anyone seeing this problem too? I don't know what to change in the

SHA-2 certificates, with no fallback implemented by server owner ???

It's because the builtin cryptography library in Windows XP doesn't support SHA-256. That library is used by MSIE.
Simple solution is to switch to another browser that doesn't use Trident
(the MSIE's web engine). e.g. Firefox or Chrome/ium or any of browsers based on those two.

My recollection is that the base version of Internet Explorer was
version 6 included in a fresh install of Windows XP. WinXP came with
IE8 and you could not uninstall it (but could hide it) as Windows
usually does not let you remove the baseline version (because HTAs -
HTML Applications - need the IE libraries). IE9 was the highest version
you could install in Windows XP. So you should update from IE8 to IE9.
Github's statement says that you cannot connect even if you updated from
IE to IE9. That is because the old SSL and use of weak certificates
made IE (and other web browsers) vulnerable to malicious use. Many
sites requires TLS, a later version of SSL, and removal of the weak
certs when you securely connect (via HTTPS) to their site.
Github won't let you insecurely connect to them. They demand HTTPS
connects. If you try an insecure connect (http://github.com), their
server will redirect to a secure connect (https://github.com).
So stop using Internet Explorer on Windows XP. Switch to a better web browser that supports TLS and other security methods when connecting to
web sites; e.g., Mozilla Firefox or Google Chrome (or their variants).
My aunt ran into the rejection problem with her Windows XP and using
Internet Explorer 9 many months ago. There was a stink back then about
using weak "secure" connects that could be exploited. She now uses
Firefox and has no problems connecting to any of the previously
problematic HTTPS web sites, plus it renders pages a lot faster with
less artifacts (bad painting) in the page's content.
Nothing you can change on Windows XP. See below in what you can do in
IE. or in the options for Internet Explorer. Those are too old to
provide secure (HTTPS) connections for many sites. Some sites still
support vulnerable SSL 2.0 connections. SSL 3.0 is basically what is
TLS 1.0 but sites are often looking for a specific encryption protocol.
Plus sites may require TLS 2.0 at a minimum, so using TLS 1.0 (available
back in IE8) and SSL 3.0 won't help. If you go into IE's advanced
options under the security section, is there a TLS option you can enable
to use that for HTTPS connects?
If you disable SSL 3.0, you will find some old sites (old in that they
still support SSL) that won't work. You should disable SSL 1.0 and SSL
2.0 and enable SSL 3.0 and leave disabled TLS 1.0, TLS 1.1, and TLS 1.2.
Then connect to every domain (not every site within domain) that uses
HTTPS (or redirects from HTTP to HTTPS) in your Favorites list to see if
any will fail to connect via SSL. Then disable SSL 3.0 and retest. You might find some sites won't connect using SSL 3.0 as they have moved to
TLS. So then disable SSL 3.0 and enable all the TLS options. Retest.
You might find some sites that are still using SSL 3.0 so you'll have to decide if you want to continue visiting those sites.
The TLS options are available in IE9, not IE8. So it is likely that you
will need to upgrade from IE8 to IE9 to get HTTPS connects to sites that
have upped their security (by getting new site certs). Although you
might upgrade to IE9 and ensure the TLS options are enabled (and SSL
2.0, at least, is disabled although SSL 3.0 should be disabled, too), it
is possible a site will look at the User-Agent header sent by your web browser. A site can refuse a connection from a web browser of a lesser version than they mandate as the minimum. In that case, you could use
the UApick add-on for IE to have it lie in doling out a UA string for a different and new web browser. However, that will also mean the site
may alter its HTML code to make it compatible with that reported web
browser but results in failures in rendering in your real web browser.
When you lie about what web browser you use, the site will assume it can
use the HTML applicable to that reported web browser (by brand and
version).

Uh, IE9 didn't work on Windows XP.
But there is no IE9 for Windows XP.

My bad. I thought IE9 could be installed on Windows XP. According to:
Nope, IE9 won't install (if that's what you mean by "didn't work) on
Windows XP according to Microsoft.
But there is no IE9 for Windows XP.
Yep, so you won't have the TLS protocols in your web browser that are required by that site (and many others that dropped SSL and switched to
TLS). So you are stuck with a decision: get blocked by sites that
require safer connects via HTTPS or, as mentioned, "Switch to a better
web browser that supports TLS and other security methods when connecting
to web sites; e.g., Mozilla Firefox or Google Chrome (or their
variants)."
A few years ago, many sites refused to let IE6 users connect. Not a
secure web browser and long unsupported. Then it was IE8. Since you
cannot get IE9 on Windows XP, you have to use some other web browser on Windows XP.
