Windows 7 Windows Public Folder

Hi, I am very in-experienced with the networking center of Windows 7. I turned on Public Folder sharing but I cannot get my client computer to connect to the Public Folder stored on the host computer. When I type in //(COMPUTER NAME HERE) it brings me a box with a message. The first few sentences say:

\\(COMPUTER NAME) is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions.

Something I should be missing but have no clue. I turned on Public Folder sharing on my host machine under its networking center but I cannot have another computer browse it. Any help much appreciated. Thanks.

BTW both computers use the same OS.
