Home networking issues

Well I just setup my PC in my room and want to network it with the PC in the living room. All my pictures, movies, music, etc etc are on that computer. I ran the network setup wizard on both computers and selected the same options for both.

Now when I go to My Network Places on the living room PC it pulls up the shared folders between both PCs. When I go to it on the one in my room it doesn't pull up anything from the living room computer.

They only thing that is on in Windows firewall on both computers. I tried the \\computer name and it works on the PC in the living room. On my computer it doesn't do anything. On the living room PC I can see all the files that I am sharing from my PC, but when I go to my PC I can't see anything.

Both have been rebooted several times and checked to make sure the work groups were the same. Changed both to the same user name and password also.

In the living room I put in \\Dmj and it will pull up my computer. Put in \\Family and it will pull up all the files I am sharing on that computer.

Now when I go to my room and type in \\Dmj or \\Family it says: "Windows cannot find "\\Family'. Check the spelling and try again, or try searching for the item by clicking the Start button and then clicking search"

I was told to open a dos window and ping the family computer. I got this:
