yes there is.

samba may be running on both ports, is resolved via a WINS
server but not via DNS.  going to 445 will save a round-trip.

a dual-mode NT4/NT5-domain server may not be accessible / 
correctly configured to be reached via DNS but is accessible
via Broadcast-mode NetBIOS, but again, it's still running
both 139 and 445.
