The port numbers depend on the version of windows you are using. You will need to enable the following ports for all versions of windows:<br />
<br />
137 - (UDP) NetBios name service<br />
138 - (UDP) NetBios datagram<br />
139 - (TCP) Netbios port for windows file and printer sharing<br />
<br />
In windows 2000 a new transport was added over port 445 so you will have to enabl eport 445 as well as the others above.<br />
<br />
I don't know of a good list of ports specifically for windows only but a general list of all ports can be found at <a href="http://www.iana.org/assignments/port-numbers" rel="ugc">http://www.iana.org/assignments/port-numbers</a><br />
<br />
Hope this helps

Anyone know which ports are used by Windows for file sharing? &nbsp;I am trying to connect to my home machine from work and have to go through a firewall, so must open the correct port(s). &nbsp;For example, I would like to be able to connect to \\maymachine\c$ from work.<br />
<br />
Also, anyone know where I can find a listing of all the reserved ports used by Windows.
