There are 3 computers on my network- I have a desktop with xp home and a laptop with xp pro and my roommate has a desktop with xp home. All 3 computers are on the same windows network and all 3 show all the other computers in the network connections window, however my desktop and laptop cannot be accessed from any computer. My roommates desktop can be accessed from both my desktop and laptop.

When I try to acces my desktop and laptop I receive this error message "You might not have permission to use the network resources. Contact the administrator of this server to find out if you have access permissions. The network path was not found."

My desktop and laptop used to be able to connect to eachother and I made no changes. I have read a lot online about different things to try (download windows server resource tool kit, change registry values to allow annoymous users access, and enabled netbios protocol). Before trying these steps one of my computers (it changed depending on which was restarted last) could not even view the other workgroup computers and the other could view itself and my roommate's comp, after trying some of these fixes I was then able to view all 3 workgroup computers from all 3 computers but I can't figure out what I have to do to access them.

I am running McAffee on both my computers and have checked that the firewall settings are set to allow ip addresses in the local range, and the windows firewall is set to allow file and printer sharing.

I can ping my roommate's comp from both of mine but neither of mine from the other one or hers.

Any other tips to help me view AND access files on my computers from the other computers on the network? Any help would really be appreciated, thanks!
