To become PCI compliant I need to disable SSLv 2 &amp;&nbsp;3 as well as TLS 1.0 on my mail server. &nbsp;On my mail server I tried to disable all of those and enable TLS 1.1 and 1.2. &nbsp;It was all good until I tried to disable TLS 1.0 which left just TLS 1.1 and 1.2. &nbsp;This is when my mail wouldn't work for my company.<br />
<br />
We have a hub 2010 Exchange server on server 2008 R2 SP1 that all my settings are setup on. &nbsp;We also have a 2010 Exchange Database server on Windows Server 2008 R2 SP1. (Do I need to make SSL/TLS changes on this server to?)<br />
<br />
I put the usual reg keys to disable:<br />
<br />
disabledbydefault - Dword value of 1<br />
Enabled - Dword value of 0<br />
<br />
enabled TLS 1.1 and 1.2: <br />
<br />
disabledbydefault - Dword value of 0<br />
Enabled - Dword value of 1<br />
<br />
I hope this is enough information.<br />
<br />
Thanks,<br />

HTTPS is a protocol for secure communication over a computer network which is widely used on the Internet. HTTPS consists of communication over Hypertext Transfer Protocol (HTTP) within a connection encrypted by Transport Layer Security (TLS) or its predecessor, Secure Sockets Layer (SSL). The main motivation for HTTPS is authentication of the visited website and to protect the privacy and integrity of the exchanged data. HTTPS is widely used for protecting page authenticity on all types of websites, securing accounts and keeping user communications, identity and web browsing private.

Installation is the act of making a computer program program ready for execution. Because the process varies programs often come with a specialized program responsible for doing whatever is needed for their installation. Installation may be part of a larger software deployment process. Cross platform installer builders that produce installers for Windows, Mac OS X and Linux include InstallAnywhere, InstallBuilder and Install4J. Installers for Microsoft Windows include Windows Installer, InstallShield, and Wise Installation Studio; free installer-authoring tools include NSIS, IzPack, Clickteam, InnoSetup, InstallSimple and WiX. Mac OS X includes Installer, and also includes a separate software updating application.
