posted March 18, 2009 9:45 AM Schannel in Vista+ Operating Systems has been upgraded to use TLS extensions as defined in RFC 3546. This can and will cause non-compliant/buggy TLS/SSL3.1 servers to fail on connect resulting in the following exception: System.InvalidOperationException: The message received was unexpected or badly formatted Setting the secure protocol to SSL3 (or a server supported protocol type) will resolve the issue as there is no support for extension methods in other secure protocols. If you are experiencing this issue and the server you are connecting to only supports TLS (no SSL3 or lower support), you will have to contact the vendor about a fix for the issue. This can affect PowerTCP FTP, PowerTCP SSL Sockets, PowerTCP Telnet for .NET and PowerTCP Mail for .NET. |
