No Inet access from laptop via XP PtP LAN

[Robert Strickland]

Hello...

I have a BIY windows machine [DT] connected to an IBM X41 Thinkpad [LT] via a R45 reverse cable. Both computers can interact w/o problems. The DT is connect to the Inet via a DSL modem, and can browse the Inet w/o problems. The LT can browse the Inet via a WiFi connection w/o problems. Both machines run XP-SP2 w/o problems.

The Problem - the LT cannot access the Inet via the PtP network. I have turned off all firewalls and antivirus programs on both computers, and the LT still can't see/connect to the Inet. In the LT browser I get the message, "Server not Found." ICS has been activated on the DT for the PtP network.

On the LT, under my network places\entire network\, there is a heading "Web Client Network." Clicking on this heading yields the error message, "Unable to browse the network. The network is not present or not started."

I can ping verizon.net on the DT successfully but not on the LT [through the PtP connection]. I can ping the DT from the LT via the PtP connection [expected since the PtP network is working].

I need help/insight on why the LT can't connect to the Inet via the PtP network. I've spent hours on this with no success. I've played with settings that I never new existed, etc. Frustrating!

Any and all help most appreciated. Thanks in advance.

How about the exact make/model of the broadband modem? How are you connecting wirelessly without a router? What's the purpose of ICS here?

[Robert Strickland]

Thanks for your time in answering.

The DSL modem is a Westhill 327w [Verizon supplied]. The wireless web connection on the IBM X51 is via a local unsecured channel [?]. No idea where it comes from. ICS is on because, somewhere/somehow, it seemed from "all sources" that it should be on. I'm don't know if that's true/false. ICS is on for the local PtP LAN, not for the desktop-modem connection.

Hope this helps. Again, thanks.

Let's see this for both computers:

Start, Run, CMD to open a command prompt:

Type the following command:

IPCONFIG /ALL

Right click in the command window and choose Select All, then hit Enter.
Paste the results in a message here.

If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.

On the Thinkpad, do this.

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"=dword:00000001
------------------- Use text before this line -----------------

Double click on the file and say Yes to the merge into registry question.

Reboot the system.

Been away for a week. Can I make these changes directly to the registry without the intervening file? Working with the registry is not a problem for me.

[johnwill]

Sure, all that script does is run regedit to make the change.
