I feel like half a moron for needing to ask this question. I have 3 PC's. One is brand new. Workgroup is workgroup. All C drives are shared with everybody, administrators, and system all in shared permissions group. Two of the machines talk without problem to each other. New device can see both others but I cannot map a drive (username/password issue) to either. I am mapping \\server\share with no success. What am I missing?
