I have one PC with XP pro loaded and other Laptop with XP home loaded. Now I made a Peer to Peer connection by myself. IP 192.168.100.2 mask 255.255.255.0 for PC and 192.168.100.3 mask 255.255.255.0 for Laptop.

Now this Peer to Peer is without any router or any hardware between them. Workgroups are same.

I am getting ping from Laptop to PC. But from PC when I tried to ping Laptop I am not getting.

I have tried to share file from both sides but I was not able to do so. But very strange thing is I tried to make connection from Laptop by using XP's inbuilt Remore Desktop connection and I was able to connect to my PC from Laptop and I have controlled my PC from Laptop. But I was not able to share my file as on normal Network.

Why this is happening ? How to solve this and share my files from both side ? What am I missing ?

People your help will be appreciable.

Two questions:
1) Is the Ethernet cable you are using between them is a cross over?
2) Did you try setting one of the computers as the gateway? Eg 192.168.100.2 would be the gateway and the other would connect to that?

There are a number of issues that must be chacked:

1. Ensure that the cable is a cross over cable and is good.

2. Firewalls block connections, and depending on the firewall that you are using on either machine configuring it may not be possible - first turn off all firewalls on both machines and try pinging.

I would have included that you needed to have a shared folder on each computer, but the ping command does not care, so if you cannot ping, I would first look at the cable and then the firewalls.

1) check your crossover cable

2) are you running a third party software that has internet security on it, if so you will need to make a rule to allow internal network 192.168.100.0 connections. If using XP SP2 check it's built in firewall rules.

3) if you are able to get icmp working from both machines and your file sharing does not work, then trying turning off simple file sharing.
