Yes. When using the FQDN, Windows Clients (and Samba Clients) use DNS to 
look up the name, and connect on Port 445.

When using the Short name, Windows/Samba Clients use WINS or NetBios to 
look up the name, and connect on port 139. Two distinctly different 
Protocols.

The Port 139 variant is used by Win9x and NT4 Clients.

The Port 445 Variant is used by Windows 2000 and later.
