ALL SSL protocols should now be DISABLED - completely.
TLS is the only secure protocol. TLS 1.0 is, technically, depreciated as well, but, if disabled, will disable most browsers and connectivity for lots of devices.
TLS 1.1 and TLS 1.2 are the only two trusted protocols.
Many ciphers need to be disabled as well and two new ones need to be added.
To take full advantage of the new protocols and ciphers, you need SERVER 2008 R2, or SERVER 2012 R2.
Server 2003 is dead - all support ends at midnight on 14 July, 2015 - including support from antivirus vendors who will no longer be pushing virus definitions or supporting products which run on Server 2003 after that date.
