Fix for that nasty port not available error message
Typical error message:
"Ports are not available: exposing port TCP 0.0.0.0: -> 0.0.0.0:0: listen tcp 0.0.0.0:: bind: An attempt was made to access a socket in a way forbidden by its access permissions."
net stop winnat
netsh int ipv4 add excludedportrange protocol=tcp startport= numberofports=1
net start winnat
Port can now be reserved :D
