Net path not found with ethernet, firewire net ok

[Guest]

Hello everyone, I need your help in this problem.
I have a laptop and desktop both WinXP prof. I also have FireWire IEE1394
and RJ-45 on both machines. I set up the network like this:
Desktop IP- 100.1.1.1 (firewire)
100.1.1.3 (ethernet RJ45)
Laptop IP- 100.1.1.2 (firewire)
100.1.1.4 (ethernet rj45)

Subnet is 255.255.255.0 for all connections

I am trying to have DSL connect to desktop and be able to use internet from
laptop.

If I connect my firewire cable, network ok each computer can see the other
and access the other with no problem. Ping and repair connection works ok.

If I use my Ethernet cable (cross over) my laptop can only see the desktop
on MSHOME workgroup but desktop can't see laptop. I checked the cable pin by
pin with multimeter, found ok as per crossover connection. I disabled windows
firewall in laptop. I used the wizard many times, no luck. I configured
manually still same problem, when trying to click on desktop from laptop it
gives error not accessible. I also try ping from DOS on both machines, they
don't see each other.

I went to services to check on Computer Browser service, NetBIOS helper and
found started same with TCP/IP NetBIOS is enabled in both machines LAN
connection. I removed all network bridges.

Last thing I did, I went to regedit and deleted Winsock so windows can
install another one, I am not sure if this would do it or not. Anyway,
nothing happened. Firewire connection works, but Ethernet does not.

I also tried WinsockxpFix.exe that I downloaded from internet, still no
luck. I went to check regedit after WinsockxpFix and found there is no
"NodeType" under NetBT so I added that under parameters with value "4" and is
shows Node Type is Mixed when I type IPCONFIG. Still, I can see my desktop in
MSHOME from laptop but when clicking it says network path not found.

As I said network works ok when using firewire I can ping, see files, copy,
etc..., but I want to have my PC at the office and laptop in the living room.

Please help, thanks

Both of your networks (Ethernet and FireWire) are using the same
subnet for their IP addresses, so they can't both work correctly.

Assign a unique subnet to each network. Use ones that are reserved
for private networks by the Internet Assigned Numbers Authority:

10.0.0.0 - 10.255.255.255
172.16.0.0 - 172.31.255.255
192.168.0.0 - 192.168.255.255

For example:

FireWire - IP addresses 10.0.0.1 and 10.0.0.2
subnet mask 255.0.0.0

Ethernet - IP addresses 192.168.0.1 and 192.168.0.2
Subnet mask 255.255.255.0

Steve, thanks for the reply.

I tried what you said, I changed my ethernet connection IP address and
subnet and restarted my computers, nothing.

This is my laptop configuration, desktop is same only IP is 192.168.0.2

I checked my connection status and it shows 0 Packets Received on laptop and
desktop.

I don't have both connections on at the same time. my firewire is disabled
now.

Any ideas? Is my Wins corrupted or NetBIOS?
thanks for the help

thanks for the help

A Windows XP network doesn't use WINS. Do you mean Winsock? If
pinging via FireWire works, then I think that Winsock is OK. NetBIOS
is used for file and printer sharing, but not for Internet access or
pinging.

In your first message, you said that the computers can't ping each
other using Ethernet. Can they ping each other now, with the
192.168.0.x IP addresses?

If not, the crossover cable could be defective. A multimeter can only
test DC connectivity. It can't tell whether a cable will work for
Ethernet, which uses high-frequency signals. Common problems in
homemade Ethernet cables are:

1. Improper wire pairing. Pins 1-2 must be from one twisted pair, and
pins 3-6 must be from another twisted pair.

2. Untwisting too much wire at the end of the cable.

Steve thanks again for your help,

I brought my friends laptop to check my cables and settings. One cable I
found defective, the other ethernet cable is working ok.

I connected laptop#2 to desktop, the lan is ok no problems at all. When I
connect laptop#1(mine) lan is not working. I made sure that all services are
working and regedit settings for NetBT are same for both laptops. still no
connection it shows my computer name in MSHOME as "unspecified" I don't know
what that is.

I un-installed McAFee from laptop#1 to see if it has effect, nothing. I even
updated my NIC driver ethrnet connection on laptop. sometimes it show the
desktop name in the workgroup with network path not found error, and
sometimes it does not show it.??

Few months ago, I was in my freind's house and he has a DSL connected to LAN
and I was able to connect to his lan with ethernet cable and getting dynamic
IP address, so my integrated connection should be ok.

I am woundering if it is compatiblity issue between the two NIC cards. My
laptop card is Broadcom 440x 10/100 Integrated Controller and Desktop card
is Realtalk.

Laptop card properties:
802.1pQOS enabled
Flow Control enabled
Speed & Duplex auto
Wake up capabilities wakeup frame

Desktop is RealTalk RTL8139/801x with Link Speed set to AUto

Ethernet is an established standard that all manufacturers use. I
don't think that there's a compatibility issue between the two NIC
cards. However, there's a small chance that a NIC might not work
reliably with a crossover cable connection. Can you try connecting
the two computers using two regular Ethernet cables and a hub or
switch?

Can laptop#1 ping the desktop computer by IP address, repeatedly and
reliably? If it can't, then the NIC on laptop#1 might be defective.

If it can ping by IP address, can it ping the desktop computer by
name? If it can't then NetBIOS settings might be wrong. In that
case:

1. Make sure that NetBIOS over TCP/IP is enabled (not default):

a. Open the Network Connections folder.
b. Right click the LAN connection and click Properties.
c. Double click Internet Protocol (TCP/IP).
d. Click Advanced.
e. Click WINS.
f. Click the Enable NetBIOS Over TCP/IP button.


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

laptop#1 can't ping desktop and desktop can't ping either. NetBIOS over
TCP/IP is enabled in both machines and ipconfig /all show NodeType is Mixed
in both.

I tried deleting NodeType from regedit before I could do that again. Do you
want me to do that in laptop1 only?

I tried deleting NodeType and restarted, nothing happened. I created
NodeType with value 1 and restarted, nothing also, could not get lan to work.
can't ping by IP or by name. When I open MSHOME it shows my latptop and
desktop under "unspecified" title, what is this about? when I click on
desktop it gives netowrk path not found.

I typed "net view" in DOS and it shows both laptop and desktop names. but
pinging does not work.

I will try to bring a hub tomorrow with two stright cable and check the my
laptop connection.

I forgot to say one more problem that I am facing with my laptop, I got an
error message when I right-click on any computer in MSHOME. Error message
says: Windows explorer has encountered a problem and needs to close. I don't
recall getting this error before, it is new to me?
