Help Required

Hello:

        I just ran nmap on my web server and received the following, rather
disturbing picture. I'm quite surprised about the netbios stuff as I have
unbound the Microsoft client and server from the nic facing the net. Any
help on what these other ports could be would be appreciated. 

Thanks

Don
