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.
