I checked back in the communication and the problem was a conflict between ports on the computer. These 3 port must be free for NCS
WebServerPort" value="8100" />
ServerTcpPort" value="8120" />
ServerHttpPort" value="8124" />
If another program use any of these ports NCS will not work.
In the case above it was Apple AIRSERVER that caused the problem.
Start with a check if there is something else that use any of these ports and stop that. Start NCS agsin.
