Cannot disable cipher suite "TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384" in IIS / Windows Server 2022

  • 772

I am using this command in Windows Server 2022, latest updates:

Disable-TlsCipherSuite -Name "TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384"

It completes without error. I then tried restarting IIS (and also the server).

But this cipher suite still shows up in SSL Labs. Is this suite part of the suite named "TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384"? Is that why it can't be turned off?

Any guidance would be greatly appreciated.
