Windows 2008 r 2 sql server refuse tls 1.0 connexion

hello,

i have sql 2008 server on windows 2008 R2;

HAVE a windows 2003 server with an application connect to a database on the sql server.

after a maintenance on our datacenter and shut down all server, the application on windows 2003 server cannot conenct anymore on sql server.

on windows 2008 R2 server, i have this error:

system log
event id 36874
source Schannel
An TLS 1.0 connection request was received from a remote client application, but none of the cipher suites supported by the client application are supported by the server. The SSL connection request has failed.

i understand that my windows server refuse tls1.0 conenxion?? so i have look on registry and see only SSL 2.0 entry on :

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols

so i have add tls 1.0 key, client and server and add this dword:
"DisabledByDefault"=dword:00000001

reboot the server and still connexion refused:

thanks for help
