No NetBIOS discovery or browsing

[W.S. Gaw]

Have a wireless and wired network with connection to
Internet. All peer-to-peer XP Pro clients.

Wireless laptop suddenly cannot see/browse any other
devices in workgroup, although it CAN ping them. Other
devices cannot see/browse the laptop but CAN ping it.
nbtstat does not show any workgroup devices. Same problem
whether I use a wireless connection or wired connection.
I took the computer to an identical network and it
exhibited the exact same problems.

On TechNet I saw "318030 You Cannot Access Shared Files
and Folders or Browse Computers in the Workgroup" which
said to check NetBios over IP settings and restart
browser service. Did both to no avail. Uninstalled and re-
installed wireless NIC driver, IP, MS Client, FnP
Sharing, etc. to no avail. This all seems to have occured
around the time I installed a Cisco VPN client, so I
uninstalled it, but that did not help.

As a workaround I created an LMHosts file on that laptop
so it can communicate with the workgroup.

Thoughts?

Run "ipconfig /all" and look at the "Node Type" at the beginning of
the output. If it says "Peer-to-Peer", that's probably the problem.
It means that the computer only uses a WINS server (which,
paradoxically, isn't available in a peer-to-peer network) for NetBIOS
name resolution.

If that's the case, run the registry editor, open this key:

HLM\System\CurrentControlSet\Services\Netbt\Parame ters

and delete these values if they're present:

NodeType
DhcpNodeType

Reboot, then try network access again.

If that doesn't fix it, open that registry key again, create a DWORD
value called "NodeType", and set it to 1 for "Broadcast" or 4 for
"Mixed".

For details, see the section on "NodeType" in this Microsoft Knowledge
