Win 7 networking appears to me to be way less friendly than WinXP networking. I have been networking multiple WinXP computers for years so I have some experience. While not a total noob, in all honesty I would not classify myself as "expert" by any means. I recently converted my (3) desktop computers to Win 7 64. This was done to allow RAIDing hard disks. All machines are set to "Share". Network is set to "Work" type network and all computers are in the same workgroup (WORKGROUP). None of the computers require passwords. I do not have anti-virus software or 3rd party firewalls installed. The only machine combination that works: Copy files from Computer A to Computer B and pull files from Computer B to Computer A Copy files from Computer C to Computer B and pull files from Computer B to Computer C I can not copy or pull any other combinations, ie, copy from A to C, B to A, B to C, etc. When attempting to open any folders I get a can not connect see network administrator message. Any helpful suggestions will be appreciated.
