HttpWebRequest results in “The request was aborted: Could not create SSL/TLS secure channel”

Question

We\'ve introduced a few .NET pages into a Classic ASP application. When a user hits one of the .NET pages we use an HttpWebRequest to get session variable values from the AS

Answer 1

We finally figured it out. In addition to disabling weak ciphers the IT guys tweaked a few other settings. They had set the Enabled (DWORD) value to 0 for HKLM\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\SSL 3.0\Client. That meant that the machine couldn't generate SSL requests. Changing Enabled from 0 to 1 for that key allowed everything to work.
