Disable-TlsCipherSuite : Exception from HRESULT: 0xD0000225

Question

When I disable the cipher TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384 in powershell of windows server, I got this error message

Disable-TlsCipherSuite : Exception from HRESULT: 0xD0000225
At line:1 char:1
+ Disable-TlsCipherSuite -Name "TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384"

    + FullyQualifiedErrorId : Exception from HRESULT: 0xD0000225,Microsoft.WindowsAuthenticationProtocols.Commands.RemoveTlsCipherSuiteCommand

What does the error mean and how to fix it? Thank you for any suggestion.

Answer 1

The error simply indicate the cipher is already disabled....

try Enable-TlsCipherSuite TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384 and Disable-TlsCipherSuite TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384 no error should appear

Answer 2

Run the Powershell as administrator and try it

It worked for me.
