Networking a vista laptop to xp pro desktops

I had no trouble connecting my laptop to my wireless router for internet access, but I cannot connect to my home network properly. I installed the LLTD Responder on the XP machines, and I can see them on the network map, but I cannot access their shared files, nor can I see them when I view the actual network. The Vista machines workgroup has the same name as the XP ones. BTW the XP machines can't seem to find the laptop either.

 

Connected!

I don't know what I did, but somehow my computer has connected now!

 

Make sure you weren't connected to the internet via a neighbour's unsecured wireless network. It happens a lot : you get full internet access but no access to your network.
