CRM Dynamics 2010 SSL Website Fails
Points of My Scenario:
1. I am troubleshooting CRM Dynamics website failure, which occurred after 3 un-installable Windows updates (KB4025337, KB4022722, and KB4034679).
2. Users get the following error when attempting to connect to website: "This page cannot be displayed. Turn on TLS1.0, TLS 1.1, and TLS 1.2 in Advanced settings and try connecting to <https://website> again"
3. TLS 1.0, TLS 1.1, and TLS 1.2 were all always checked (turned on) in the Advanced tab of the Internet Options dialog box.
4. In IIS (on a Windows Server 2008 R2 SP1 member server) the "Microsoft Dynamics CRM" website bindings include http (over port 'wxyz'), and https (over port 'efgh').
5. Surprisingly, the "Browse *:wxyz (http)" link works, WHILE the "Browse a.b.c.d:efgh (https)" link fails with the generic error "Internet Explorer cannot display the webpage"
6. When the user tests the non-SSL version of the website, (s)he gets the error "Not Authorized. HTTP Error 401. The requested resource requires user authentication."
7. The https (SSL) and the http (regular, unsecure) links are identical - so, whereas the https (SSL) link complains about the absence of settings that are truly present, http complains that the user is not authorized.
QUESTION: What shall I do next to troubleshoot/resolve this failure of the CRM Dynamics website?
I am grateful for any help I can get. :-)

1. The CRM Dynamics website has been working for years.
2. The failure happened after Windows updates
3. I just resolved the issue (~20 minutes ago) by removing and re-applying the server-level website-level certificates.
Many thanks for your prompt response and suggestions.
@Moderator: what do I do with the points, since I have resolved my own question? I would like to award them to Feridun for responding so promptly with well thought-out insights, and suggestions. What is the protocol.
Grateful,
Walt
