How to find what ports your server is listening on and which service is listening on each port

How can you find what ports your server is listening on and which service is listening on each port? The traditional way is to open a command prompt and type netstat –anb. An even better way however is to use the free tool Port Reporter, which is available from the Microsoft Download Center. For a good introduction to Port Reporter and its capabilities, see http://support.microsoft.com/default.aspx?scid=kb;en-us;837243. Not many admins know about this cool tool from Microsoft!
