ICS problems with 2xWin2000 and 1 XP

Setup is a follows.
Broadband modem through USB to Win2000 ICS machine. One crossover cable to WinXP machine.(Internet works fine)
(again from Win2000 ICS)One crossover to female-female rj45 to non-crossover 10mbit cable to PCMCIA in Thinkpad running Win2000.

The XP and Desktop Win2000 machines work fine, network and internet, but a problem arises with the laptop and desktop win2000s. They both see eachother in my network places, but the laptop doesn't get internet access. the network is running 10mbit between these two, and 100mbit between xp and "server ".

Also the XP and Laptop can't see eachother.
Filetransfer works between all computers that can see eachother.

How do I get it internet to work, and a solution to the xp and laptop to see eachother would be useful.

I'll try to post any missing info you might have.

 

To make sure I'm clear -

You have:

- a w2K desktop with a modem connection via USB and 2 network cards. The desktop is running as the ICS host. Call this one PC-A.

- an XP PC connected to one network card on PC-A. Working fine for internet and file sharing with PC-A. Call this one PC-B.

- a w2K laptop connected to a 2nd NIC on PC-A that does not get internet access. Call this one PC-C.

If any of the above isn't correct, please say what is.

Is PC-A providing IP addressing information for both PC-B & PC-C automatically? It probably is and in this case, that is not a good thing.

Is there any possibility of your spending $50 or so for a router/switch to make your life faster and simpler?

If not, there is a way to set up where it will work but I'll hold off on that pending confirmation of your setup.

 

Ummm I am not sure what you mean by this One crossover to female-female rj45 to non-crossover 10mbit cable to PCMCIA in Thinkpad running Win2000.
I will assume and I hate to that you have 2 nics in the 2000 machine one to each client PC XP and lappy correct?

 

That is exactly my setup.

What I meant is that the PCMCIA card doesn't have a crossovercable, so I connected it to a box with female-female rj45 connectors, and then a crossover cable to the PC-A. File serving is fine.

Any solution that would save me from buying anything extra would be appreciated. So at the moment, a switch is a back-up if nothing else helps.





EDIT - The laptop and the XP now see eachother. Internet no worky on the laptop, though.

 

Hmmmmm. Do the following and post the contents of the resulting text files. Identify which PC produced what text file.

Do NOT mask any IP address values. Need to see exactly what is there.

start~run~cmd
ipconfig /all > c:\config.txt

 

Uh, how do I make it not to mask the IP?

I'll just post these, and hope they help.

XP (PC-B):

Laptop (PC-C):

Server (PC-A):

 

Thanks for posting it. The Masking is something some folks decide they have to do to keep from making some information public. I have no idea why but have seen it a bunch.

They generate a report that contains 192.168.0.1 and they post 192.168.xxx.xxx which is pretty useless for some sorts of problems.

I do note that your lease expiration is in Finnish (at least, based on maaliskuuta I assume it is). Is your OS English or some other language? Not sure it matters in networking but just something I haven't run across before.

IP Address. . : fe80::4:61ff:fe47:3ed6%4
IP Address. . : fe80:::5efe:192.168.0.145%2
and several others indicate you have the IP v6 support installed. Not needed and not wanted at this point. It was probably a hotfix you installed so add/remove and you should see it. Uninstall it.

You have an "Automatic Tunneling Pseudo-Interface" listed among your network cards. This is a thing that IP v6 put there and isn't doing anything except causing clutter. Device manager and remove it.

You have a "Connection-Specific DNS Suffix" listed for your network cards. Not needed usually and can cause problems at times. For now, remove it from all your internal network cards (IP addresses in the 192.168.x.x range). May remove it from the remaining cards at some point but not right this moment.

The laptop (PC-C) has an APIPA assigned IP address and subnet mask. Several problems with that. First, it indicated the PC is not seeing the ICS DHCP piece (assigns addressing information). Next, it puts the PC in a totally different network than the rest of the PCs so no way they can ever see each other well enough to share files and such. Usual cause is either the NIC setting (speed, duplexing, similar), a bad network cable (bad ends, broken wire, wrong wiring), or (rarely) a network setup that isn't properly installed or is broken. Same issue with NIC#2 (the Realtek) on the 2000 server.

 

Hmmm..... This is getting weirder and weirder.
I can't find the "Automatic Tunneling Pseudo-Interface ", nor can I find myself to have installed IPv6 in any Hotfix, the windows site was very non-helpfull in finding what hotfix would have done that, only one I found was this Hotfix 817778

How is the Connection Specified DNS removed?

I'll try to disable the APIPA on both latop and server, see if it has any effect.

 

How is the Connection Specified DNS removed?

In the TCP/IP properties section of your network card, you should find the block for it and can just delete what is there. Should stay gone.

The effect of disabling APIPA, assuming the PC can't find the DHCP server, will be to slow the boot process way down and leave the PC off the network when it finally loads up all the way.

note: the dang link is one that is structured so this forum's software can't handle it properly. Confused by the [LN] piece. You will have to copy the whole line and paste it in a browser window to get there. Clicking on the underlined link part above won't work.

 

Well, diabling APIPA made no difference whatsoever. I can still get files from the Server machine.

I disabled IPv6 on the XP machine, the others didn't have it. Made no difference, except that the XP machine doesn't have internet connection any more, even after reinstalling the IPv6.

I found a interesting thing with the server though, the connection sharing the internet(connection 2), has a wierd glitch. In the sharing tab, it would only show that it's sharing it to the XP, machine, but now(after paying with IPv6) it's blank, and no machines get internet from it. So how do I change it, so that I tell it share it to all computers in the local network?

I think the root of the problem it here.



EDIT - XP machine back online after installing all connections again.

 

Um....
Using the laptop, I get funny results. I can "/net view" and find the laptop and the server. But I can't ping the server.

When in "my network places ", I see all computers, but can't connect to XP machine(path not found). I can however get files from my server. WIERD.

 

Assuming that all the PCs are getting to the internet without problems and you just want them to share files/printers, at this point I'd suggest you install NetBeui on all the PCs and see if things work then.

Note that ping and a few other commands are IP specific and if they didn't work before, they won't work after.
