trying to link two pcs together
 
Hi

I got 2 pcs which I want to connect via a x-over cable. I plugged them and they pick up each other but they dont seem to aquire an Ip address. I have made sure that they both obtain an IP address automatically.

any ideas why this two are not linking? both are win xp.

Assign the ip's automatically?

sorry I meant that I made sure that both have the option "Obtain an IP address automatically" which they do but they still dont seem to be to be able to aquire an ip address as it waits quiet a long time on this part of connection and then displays the limited connectivity error message.

Its because you don't have a DHCP server to provide the IP addresses. If you are just connecting the PC's to each other then you will need to manually assign them IP addresses.

i managed to connect these two pcs together last night using wifi but now that I am trying to connect them using a wire it does not seem to what to share the files. I can see both pcs on my Workgroups but when I double click on the pc icon I get that it is not accessible and that I may not have permission. any ideas what I should look for?

Except they're XP so as long as the NICs are set to assign an IP address automatically, if a DHCP server isn't contactable, they'll assign their own IP addresses (169.x.x.x)

Go to the advanced tab in the windows firewall (even if you've got it turned off, as it lies) and you'll see a list of network connections to apply the firewall to.
Make sure your local area connection on both machines is unticked.

Are they in the SAME workgroup? Also, are you using the same user id and password on both PCs?

I have done this but now it is saying that I cannot access the workgroup on the one pc so I cannot even see the pcs and on the other pc I see the two pcs on the workgroup but I cannot connect.

Can you ping one PC from the other?
Do it from both PC's

Have you got a publicly shared folder on both PC's?

I cant ping them. I trying ping each other on each machine and just got a request timed out. I do have shared folder on the one pc.

Re: trying to link two pcs together
 
You're pinging their ip addresses not their computer names

ok, do an ipconfig /all on each machine (from cmd prompt), make sure that their ip addresses are of the same range, so 169.x.x.x with a subnet mask of 255.0.0.0

Actually, if they're 169.x.x.x addresses you can post their ipconfig information.

pc 1 : ip address: 169.123.1.2
subnet : 255.0.0.0

pc 2 : ip address: 169.123.1.1
subnet : 255.0.0.0

still have the same problem cannot ping them

Firstly, note if any link lights(where present) are lit on the back of the network cards. If you do have indicator lights and they aren't lit, you either have a faulty cable or network adapter.

Then disable all firewalls on each PC.

Set up both PC's with Static IP adresses

1st PC
IP address 192.168.0.1
S/N Mask 255.255.255.0

2nd PC
IP Adress 192.168.0.2
S/N Mask 255.255.255.0

on each PC in turn try to ping 127.0.0.1, this is an "IP loopback" address that will verify that the IP stack is working, then try pinging the machines own IP address, only after those two ping tests have worked move on to pinging PC 1 from PC 2(and vice versa).

Once you've got basic IP connectivity we can move on to other things

ok, set one PC to an IP of 192.168.0.1 subnet mask 255.255.255.0 and the other to 192.168.0.2 subnet mask 255.255.255.0 then try again

[edit] Jon T just beat me to it heh

I set up as sugested and the results are as follows

pc 1: pings 127.0.0.1 Excellant
pings 192.168.0.1 Excellant

PC 2: pings 127.0.0.1 Excellant
pings 192.168.0.2 Failed

I did an ipconfig on pc2 and found that the ipconfig reading did not match what I had entered in on the local area connection properties. perhaps this is why it does not work. I trid disabling and enabling the connection as well as repairing but still the same answer.
