your /etc/services file should have info that you can always look at (
but its a text file, does not indicate whats actually running where.. )

to check for whats actually on there, use something like lsof ( the man
page for lsof is very well done, a worthy read ). a Shortcut here :

lsof -i :445

will tell you whats up with your port 445.
