Zero knowledge of networks - help please!

Thanks. I assume it is necessary to switch off both the Windows Firewall (if on), and any third party firewall software? I did what you suggest earlier (regarding the IP addresses and subnet masks), so I hope this will solve the mystery!

By the way, obviously I don't want to go onto the internet without a firewall, however won't I get the same problems again when I re-enable the firewall?

Thank you for your help. :)

If you have a router you won't need your software firewall turned on really.
 
Sorry for taking so long to reply, been too busy to try this. Anyway, I tried what you suggested, and yes everything now works. I can ping both ways between the computers, and see the folder I shared on the XP machine on the 7 machine, and vice versa.

However to do this I had to disable the third party firewall, therefore I decided to disable the internet connection too. Is it easy to keep able to keep the connectivity whilst having the firewall enabled?

Likewise, what was the need for setting up a static IP address in the TCP/IP settings for the LAN? I don’t understand how the machines ‘know’ the IP address of the other machine, if that makes sense. I simply told them what there own IP addresses are (i.e. 192.168.0.4 and .5), but you don’t tell each machine the other computers IP address anywhere, so why is it important? I guess it is just like giving the computer a name? If it doesn't have an IP address it is nameless, therefore the other computer doesn't know who or what it is talking to? Apologies if that is a foolish question…

Likewise I set up static IP addresses for the wireless router (obviously different to the above), should I leave that or change it back to DHCP?
 
Hmmm this is odd I networked the computers together yesterday and I couldn't see the XP notebook on the 7 desktop until I re-enabled the Windows Firewall on the XP machine! I left the third party firewall on too and it still worked, not that I'm complaining ofc!

However, for some reason the internet doesn't work (using Firefox) on the XP notebook when the LAN is enabled, however no such problems on the 7 machine.

Any ideas please? :)

On the XP machine do an ipconfig and post the results, screenshot please.
