I gave ip addresses to both the laptops as 192.168.2.1 & 192.168.2.2. I shared my drive and mapped it also. Computer name as well as the drive name is shown on the other system but when I open it , it shows "access denied". I have given all the permissions to that shared drive. When I change permissions on mapped drive access is denied on that too. Please help me.:(

Make sure you have the same user names on both PCs.
