Scope of Windows local network.

[Michael Chare]

What defines the scope of a Network as shown in Windows Explorer - for a
home PC without a Domain server.

Would Windows Explorer ever find a PC that is the other side of a router -
i.e. different IP subset. - Is there anything that can be done to make this
possible?

What port does a Vista PC use for communicating with other PCs for file and
printer sharing?

Its all based on the industry standard Transmission Communication
Protocol/Internet Protocol.

By network scope, you mean addressing issues? Home networks generally use a
non-routable IP address behind the router. Usually 192.168.0.xxx with a
subnet mask of 255.255.255.0. To traverse the router it uses what is called
Network Address Translation. Computers will generally be on the same
workgroup, but no domain as there is no domain controller. If you want to go
the whole route you can, by that is the general rule.

You would have to be on a VPN for that.

What port does a Vista PC use for communicating with other PCs for file
and printer sharing?

TCP ports 139 and 445, and UDP ports 137 and 138
