Peer to peer stopped after installing ICS

[DaveOddie]

Hello again,

I connected my new PC with its Asus A7n8x in-built NIC to the old one that uses a 3com PCI NIC via a crossover cable. Both are running Win 98SE.

I was stunned when it just worked right away and for the first time in a long computing career I thought Mircosoft deserved a pat on the back for making things so easy. It didn't last.

I was happily copying data from the old box to the new when I decided to try Internet Connection Sharing. So I followed the instructions and since then the "network" has gone AWOL.

Neither box can see the on ther anymore in Network Neighborhood. Can't even ping each other.

I think I know why, but don't know how to change things back if my suspicions are correct.

One PC has an IP address starting 192 while the other has one that starts 169.

So, from what I have read this means they are on a different sub-nets and won't be able to see each other (and they can't!).

So I assume attempting to install ICS changed one of the PC's addressing details but what I don't know is which one and how to change things back the way they were.

On the original configuration I did nothing except put the cable in, install the drivers for the 3com card in the old box, name the PC's and put them in the same workgroup and let Win 98SE do the rest.

I didn't assign my own IP addresses or anything like that.

So has anyone any idea how to get the PC's back onto the same sub-net (assuming that is my problem) and which one I should fiddle with?

I am not that bothered about ICS so I will be happy enough if I can get them back talking again.

A 169 ip is assigned when the computer can't connect to the network; you would get it, for example, if your network cable was unplugged. I'm guessing you either have ics set up incorrectly or that maybe you have a cable problem that you didn't have before.

Personally, I would get a router, but for ics help check

Internet Connection Sharing. Good luck.

Also, here is a little more detail on the 169 ip issue:

Thanks for the reply.

I followed the link about 169 and I must admit I was wondering where and how IP addresses were being allocated anyway.

The original config of just the two PC's on the crossover cable and no ICS worked fine so the IP addresses must have been set up OK somehow.

The PC showing the 169 is the new one which means the NIC is the one built into the Asus A7N8X motherboard. I'll check out if its set up and working OK.

I'll also check the cabling is OK - I did'nt touch it and PC's are right by each other as the main reason for doing this is just to copy across a great deal of data off the old to the new without going via some tedious removable media.

The ICS was just me mucking about, so I won't do that again in a hurry and as I said I don't really care if its not available to me if I can fix the problem.

As to a router, well once the data transfer is complete the PC's won't be networked for the forseeable future. The old PC is going in my sons bedroom and maybe we will connect up a network sometime, but I don't think the wife would like cable running down the stairs from his bedroom into my study!

Another thing has just occured to me.

The 169 PC is the server in the Internet Connection Sharing set-up. So is there a way to turn off / get rid of ICS on the server to see if that cures the problem?

You can just turn off ICS completely on both machines. If you are using it, one machine should be specified as server and the other as client. Haven't used ics in a long time so don't remember all the details. But, from what you are saying there doesn't seem to be much need for internet connection sharing anyway -- all you want to do is move files from one machine to the other, and after that they won't be networked. You can probably make ics work, but for your immediate needs it has just made your life more difficult!

If by some chance you are using winxp on both machines, you might try a system restore to before you tried ics.

If you do eventually want the machines networked, you have many options besides direct cabling, e.g. wireless, phoneline, powerline.

I was hoping you could, but how?

I have not seen anything obvious anywhere.
