我希望这是正确的论坛;我首先在Stack超级用户上发布了这个，并立即得到了回报，没有任何解释。然后我尝试了Stack的网络工程站点，但那里没有我的标签......所以现在我在这里尝试。如果我知道的话，我会很高兴将它移到正确的论坛。
我们正在运行Windows Server 2008 R2。 TLS 1.0一段时间以来一直不兼容PCI，并且通过Windows注册表禁用它很容易。但是，在过去，禁用TLS 1.0会给我们带来两个问题：
问题＃1已修复MS补丁KB3080079，但是一旦TLS 1.0被禁用，我们的网站仍然会脱机。在禁用TLS 1.0时，我需要做些什么才能让IIS满意并且网站在线？
以下是错误消息，仅在注册表中禁用TLS 1.0且服务器重新启动后才会出现：

注意：在注册表中手动启用了TLS 1.1和1.2。
答案 0 :(得分：0)
我认为当TLS 1.0被禁用时，我发现SQL Server实际上是问题的原因。 （这会使我们所有的网站崩溃。）有一个解决方法：https://support.microsoft.com/en-us/kb/3135244
