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!
