The problem is the node type. I suspect if we fix that, you'll be networking.
Create a file in notepad named NODETYPE.REG with the following contents:
You should have 3 boxes on the bottom in NOTEPAD.
1)Filename : NODETYPE.REG
2)Save as type: all files
3)Encoding: ANSI
If you do not change it from txt type to All files type, then the file will actually be NODETYPE.REG.txt, this won't accomplish the desired result.
------------------- Use text after this line -------------------
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NetBT\Parameters]
"NodeType"=-
"DhcpNodeType"=-
------------------- Use text before this line -----------------
Double click on the file and say Yes to the merge into registry question.
Reboot the computer.
