Disabling RC4 and DES in Win2012 Production SQL Servers.

Hi,

The customer have SQL production servers n windows 2012. 

They came with the question will there be any effect for SQL Servers if we disable both RC4 and Des. 

I am not sure what can happen to the application if we disable this both. I dont have any idea on these. Please can anyone guide how to disable if these both will not impact the SQL Server. 

Thanks,

Jo
