Vista - XP - Vista network

I have 2 XP computers & 2 vista computers on a network . All computers have the same workgroup name. All computers have all drives & folders checked for File shareing. I can do anything I need to copy or modify files from the XP computers using the Vista computers. I can see all drives. folders on the Vista Computers from the XP computers but cannot open any of the folders. so the system works well opening Xp files from Vista computers but not the other way around...any ideas...????

Vista firewall, AV, permissions.

I open Firewall settings - Advanced, but only see check boxes for local area connections 1 & 2 or restore default button....nothing about permissions.
I even turn off firewall but no difference. Message on other computer says Access denied....You may not have permission to use this network resource....

I have had similar issues with Vista when trying to share drives as opposed to folders across a Vista - XP private network. If haven't done so, try sharing a subfolder separately and ensuring "everyone" is added to the permissions list.
