I was planning to setup LAG between the three switches using the SFP ports to b Spring is here, the blossom is out and the sun is (sort-of) Note: RC4 cipher enabled by default on Server 2012 and 2012 R2 is RC4 128/128. AES can be used to protect electronic data. For anyone who wants to do this using powershell, it is a bit trickier than other registry keys because of the forward slash in the key names. If these registry keys are not present, the Schannel.dll rebuilds the keys when you restart the computer. Also, note that Keep the tool around and run it against your web sites every now and then-- every 3/4 months or 6 months. To find Supported Encryption Types you can manually set, please refer to Supported Encryption Types Bit Flags. I have exported and diffed this servers registry keys with another, where the cipher is disabled properly. TLS_RSA_WITH_RC4_128_SHA (rsa 2048) - C. I have modified the registry of the server in the below location to disable the RC4 cipher suite on the server. Asking for help, clarification, or responding to other answers. In order to remain compliant or achieve secure ratings, removing or disabling weaker protocols or cipher suites has become a must.
