windows 8 RDP Child Session - how to use?

• I trying to use RDP child sessions as described in https://msdn.microsoft.com/en-us/library/jj553447(v=vs.85).aspx My code: private void button1_Click(object sender, EventArgs e) { axMsRdpClient9NotSafeForScripting1.Server = "localhost"; Object True = true; MSTSCLib.IMsRdpExtendedSettings extSettings = (MSTSCLib.IMsRdpExtendedSettings)axMsRdpClient9NotSafeForScripting1.GetOcx(); extSettings.set_Property("ConnectToChildSession", True); axMsRdpClient9NotSafeForScripting1.Connect(); } But I get an exception on the method Connect(): "Value does not fall within extended range". Сan anyone help me?

• Answer:

  You need to enable Credential Security Service Provider Support in order to connect to a client session. Do this before you connect... IMsRdpClient7 msRdpClient = this.axMsRdpClient9NotSafeForScripting1.GetOcx() as IMsRdpClient7; msRdpClient.AdvancedSettings7.EnableCredSspSupport = true;
