NetBIOS over TCP/IP

[xpanmanx]

A while back, I got it in my head that I can "disable NetBIOS over TCP/IP" on my Windows
2000 network. And, in fact, things seem fine with that setting disabled.

I've recently been experimenting with a Windows Mobile 2003 Pocket PC, and connecting it
to my network via the built-in WiFi.

I cannot map shares unless I enable NetBIOS over TCP/IP on the target server. Why is
this?

It's is the way MS Networking works. It is based on NetBIOS. TCP/IP is used as a routable
transport.

So if you want to share info in a NT Domain or in a MS Workgroup you NEED NetBIOS over IP.
If you were NOT accessing the Internet and you had only a LAN, than NetBEUI which is NetBIOS
with its own non-routable transport could be used.

If this was a LAN w/o the Internet another alternative would be NetBIOS over IPX/SPX.
However, if you want to access the Internet and have MS shares being accessed then NetBIOS
over IP is what is in order. Of course I highly recommend a FireWall of some kind.

Thanks, Dave.

Curiously, I can turn off NetBIOS over TCP/IP on all the servers, and the Windows XP
workstations can still see everything. But this PocketPC seems to need NetBIOS. Is that
just a difference in the client OS?

Yes.

Win9x/ME and Pocket PC don't use the additional TCP or UDP ports.
