Info On Trouble Sharing Folders?

I used easy transfer to move files from an old Xp pc to windows vista pc. I then tried to do shared folders between the new pc and my laptop which is an xp system. I can see the laptop on my vista pc network and I can access the laptop files. When I click on folders in my vista machine that I identified to share they show as shared. When I go to my laptop with xp the new pc shows up in network places. However, as soon as I click on the icon for the shared folders I get an access denied -don't have permission to access. On my vista machine I have password protection off , discovery on, public folder on and file sharing on. The public folder allows me to click on its folders with no access issues but all the files that were transfered using easy transfer say access denied,
