NIS and Windows Firewall

Hi,

 

When I go to Windows Security Centre, Norton says the firewall is on, but when I click on Windows Firewall, it says it is off.

 

Also telling me that two or more firewalls running at the same time can cause conflict with each other.

 

If I look in 'change settings' it says WF is off. 

 

Is this Norton just reporting that its own firewall is on,  or am I missing something here?

 

Just need some clarification, thank you.
