如何在 IIS7 Windows Server 2008 R2 上启用 TLS1.2

Question

I have a Windows Server 2008 R2 that serves services on IIS7. I enabled TLS 1.2 as you see below

But unfortunately, on of my client is said that they got SSL connection error using TLS 1.2. When I tried to check using OpenSSL, really there is a problem with TLS 1.2.

So, could you please help me, how can I fix this issue?

Answer 1

From Technet

For TLS 1.2 to be enabled and negotiated on servers that run Windows Server 2008 R2, you MUST create the "DisabledByDefault" entry in the appropriate subkey (Client, Server) and set it to "0". The entry will not be seen in the registry and it is set to "1" by default.
