can't network 3rd computer...

Hi everyone,

Could really use some help on this one. Searched all over
the net and can't find a solution. Here's the problem. I
had two computers networked together through Netgear's
Gateway Router (RT314). I connected them by using
the "Set up a some or small office network" wizard. Both
computers can see each other without a problem. Printing
through a shared printer is fine too. Now I am running
into a problem connecting a 3rd computer.

Here is some technical info:

- All three are running WinXP Pro, NTFS formatting. (the
3rd computer is a fresh install with all updates from the
microsoft website.)
- IFC (internet firewall connection) is disabled on all 3
- In Properties of the Local Area Network (Status
Enabled), is shows Client for Microsoft Networks, File
and Printer Sharing for Microsoft Networks, QoS Packet
Scheduler & Internet Protocol (TCP/IP), installed for all
3 computers.


- Clicking on "View Workgroup Computers" on Computer1 or
Computer2, shows me all 3 computers BUT when I double
click on the 3rd computer, I get the following error:

"\\Computer3 is not accessible. You might not have
permission to use this network resource. Contact the
administrator of this server to find out if you have
access permissions.

The network path was not found."

I don't even get this far on Computer3. I get this same
error in just trying to access "View Workgroup Computers"
on Computer3 (once I didn't get this error. It only
showed itself listed but haven't been able to get to to
show again)

- Computer3 can ping Computers 1 & 2 but 1 & 2 can't ping
Computer3.

It seems to be acting like the firewall is set but I've
checked over and over and the ICF is not enabled on any
of the computers.

Would anyone have any idea on what the problem might be?
I've tried finding solutions on the net with no success.
Any help would be greatly appreciated. Thanks!

Click to expand...

1. Permanently disable XP's built-in Internet Connection Firewall on
local area network connections -- it's for use only on a direct modem
connection to the Internet. Disable and un-install all other
firewalls while troubleshooting. Details here:

Windows XP Internet Connection Firewall
http://www.practicallynetworked.com/sharing/xp/ic_firewall.htm

2. Use only one protocol for File and Printer Sharing. If the network
needs more than one protocol, unbind File and Printer Sharing from all
but one of them. Details here:

Windows XP Network Protocols
http://www.practicallynetworked.com/sharing/xp/network_protocols.htm

3. Make sure that NetBIOS over TCP/IP is enabled on all computers.
Details here:

Enable NetBIOS Over TCP/IP (NetBT)
http://www.practicallynetworked.com/sharing/troubleshoot/netbt.htm

4. Run "ipconfig /all" on Computer 3 and look at the "Node Type" at
the beginning of the output. If it says "Peer-to-Peer" (which should
be "Point-to-Point, but Microsoft got it wrong) that's the problem.
It means that the computer only uses a WINS server, which isn't
available on a true 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\Parameters

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
