Hello,
I host a Windows 2012 r2 Server & Windows 2016 Server and looking for some help with respect to SSL ciphers.
Below are 2 ciphers for which I have a question:
TLS_DHE_RSA_WITH_AES_128_GCM_SHA256 (0x9e) DH 2048 bits FS 128
TLS_DHE_RSA_WITH_AES_256_GCM_SHA384 (0x9f) DH 2048 bits FS 256
Why is the stronger form not in Windows Server 2012R2? Is there any way or patch available for windows 2012r2 which can be installed so that we can have these ciphers available in the server to be enabled/disabled.
You can follow along here to add them.

Hi,
Check out the article below describes an update in which new TLS cipher suites are added and cipher suite priorities are changed in Windows Server 2012 R2:
