RDP Module hangs against systems with interactive logon messages #51

Hello! I was testing ncrack today against my Windows 2012 R2 server. It works beautifully with standard RDP. However, when the interactive logon message is presented prior to the authentication step, ncrack seems to try over and over but gets nowhere.

More information about interactive logon messages can be found here: https://docs.microsoft.com/en-us/windows/security/threat-protection/security-policy-settings/interactive-logon-message-text-for-users-attempting-to-log-on

Thanks for reporting. That's something that needs fixing indeed. I have been aware of this issue for some time but never got enough time to look into yet.

I think the issue is present with telnet service as well.
