In this apartment I live in, I have 2 other roommates, all are connected to the internet with a router in my room. However, my two other roommates computers can share files together in "My Network Place" while mine cannot. In my own "My Network Place", I only see my own computer's identity and not theirs, and they cannot see my computer in their "My Network Place". I've tried just about every single possible way to fix this but to no aveil. All the configuration for my computer is set exactly the same as my roommates' computers, like the name of the workgroup and so on... please help, helpful GAF !
