It is recommended that you disable all unnecessary encryption methods and protocols on the grounds of security. If you disable redundant protocols and methods, older platforms and systems may not be able to establish connections with web applications anymore. Therefore, you must decide which protocols and methods are necessary, based on the platforms required.
NOTE: The software "IIS Crypto" from Nartac Software is recommended for disabling encryption methods and protocols.
