3DES only available for local domains/router segments/local networks if needed. NOT FOR THE INTERNET.
SCHANNEL : The 3DES Cipher should be used - if needed at all - ONLY selectively and definitely kept blocked - disabled - for Internet Connections ranging outside of a local Network boundary (or outside of proxied Segments or NAT Domains or also when not being used through either encrypted VPN Tunnels).
I recommend this because it is weak. (64bit ciphers are generally considered weak now because of their limitation).
