I believe this is because "The minimum operating system that will support TLS 1.2 is Windows Server 2008 R2.
Windows Server 2003 and 2008 are no longer supported by Microsoft.  The TLS 1.2 protocol is not available, so if you are still running on a Windows 2003 server, you need to upgrade to a newer server soon.  If you are using Server 2008, then you can upgrade to R2.
For more information, please see: Support for SSL/TLS protocols on Windows "

as stated here: http://help.ablecommerce.com/FAQs/AbleCommerceGold/Enabling_Support_for_TLS_1.2.htm


the problem is that the windows 2003 server can connect to windows 2008 R2 server with sql 2008 for many years, and suddently after reboot all it stop working. so i am sure we can deal with cipher or tls regkey on windows 2008 R2 server to accept tl1.0

Sorry it wasn't clear enough that that's the point I was trying to make - I think that can no longer be done and you will have to try implement/use the TLS 1.2 as noted at link I posted above.
