i have a wireless network set up in my home and all the computers can connect to the internet just fine. if i go to network places all 3 computers show up but when i try to access them i get an error message. it says i do not have permission. i have permission, they are all my computers. i would like to have full access to all computers from any of the three. i think this problem is also stopping me from using one printer for all computers

You need to give permission on the other computers by creating a user. The quickest way to do this is to set up your user on the other PCs (including the same password).

i dont have any users set up on my computers at all though. all of my computers are setup as administrator
