I have three computers on my wired network. One computer is an iMac, one is a Ubuntu and the last is an XP machine. When I am on the iMac and use the Go to menu and select server I see the computer I need to logon to plus the shared directories, but when I click on the directory on the remote computer I get an error that says "Volume failed to mount the volume "Public" failed to mount". I am at a loss on what to do. I am new to Mac networking so please give me as much info as possible. Thanks.
