I have windows xp pro one wireless and one with a NIC card running through a router. I have completed the home networking install but I still can't access the shared files. I can access the files on the laptop through the desktop but I can only see them on the laptop and can't access them. It tells me: it is not accessible. You might not have permission to use this network resource. Contact the admin to see if you have access permissions. please help I have been trying to fix this for a while now.
