Home Networking problem.........

[[fastdetect]]

Hello,
(2 Xp Comps, 100Mbps-Crossover/Router)
I am having a problem with a 2-pc network without an interent connection......

it seems that one pc can send and recieve some packets ----- and the other pc can send packets

and not recieve them at ALL look :

Also in Netwrok-N sometimes one of the pc's can't see the wrokgroup at all (MSHOME)
(also no Physical address on one of my pc's)
http://klitev.port5.com/p1.jpg
Here is what i already tried on both pcs:

-Created a new admin account
-Tried the command Ntsh to reset everything and it did reset but no look
-Checked if certin services were running
-Unique names same workgroup
-Lots of other stuff.......



Also this is a home network... and i tired this with crossover and my router but the results were

the same............... :(


what the HELL is going on here? its definetly not hardware




thnx

Do you have XP's firewall enabled?

If you are using a router, you need to change the IPs to 192.168.1.100 192.168.1.101
and use the subnet:
255.255.255.0
and make sure the gateway is set to the router IP:
192.168.1.1 (could also be 192.168.0.1)

If you're using a router, then you don't use crossover cables, rather you use standard straight cables, one from each computers NIC, into one of the ports on the built in switch of the router. Not the uplink port of the router.

What kind of router?

Obtaining a 169.254.XXX.XXX address means the computers did not detect a DHCP server on the network, and are attempting to auto-configure themselves.

If you only have two computers, and you are only going to peer to peer them then you don't even need the router, just use your crossover cable from computer to computer.

j79zlr That's assuming the router has a 192.168.1.XXX LAN scheme, which many do not. Also you're need DNS entries, else you don't surf anything. But he doesn't seem to have a WAN connection, so you don't need DNS, you don't even need the gateway entry.

what kind of config i need for a peer-to-peer network (crossover)? because one day my LAN just gaveoout and since then i can't make the 2 comps communicate

also no firewall is on....

thnx

Ah really? So it was working before?

For just a peer to peer (P2P) network, for only two computers, you can have two approaches.

1) Two computers, one NIC in each, connect with a crossover cable from NIC to NIC. As long as both NICs are the same speed, it usually works fine.

2) Two computers, one NIC in each, and in between...will be a hub, or a switch, or a router which happens to have a built in switch on the LAN side. Each NIC connects to a standard port on the hub or switch with a standard patch cable, not crossover.

Now, for either setup above, you need to set your protocols. Assuming you're using TCP/IP, you need to make sure the IP scheme is same, meaning 192.168.1.XXX or 192.168.0.XXX.

Computer A
192.168.1.11
255.255.255.0

Computer B
192.168.1.12
255.255.255.0

That should do it. As long as no firewalls are running on either computer, they should be able to ping each other. If they cannot...then we must look at a hardware failure, such as a bad NIC, bad patch cable, bad hub or switch. I especially look this way because you said it was working before.

hmmmmmmmmmmm i'll give it a try thnx....... also note that both xp comps say "LAN Connection connected" (little popup) if i disconnect the cable/router so they both know if they are conencted....... if any other solutions popup in anyone's head let me know


thnx
