Im trying to run a simple command from a DOS prompt. The command is following:

netsh firewall add portopening protocol=TCP port=5900 name="VNCEnterprise2" mode=enable scope=subnet

Shell '%COMSPEC% /C "netsh firewall add portopening protocol=TCP port=5900 name="VNCEnterprise2" mode=enable scope=subnet"
