Home networking - XP logins
I've got an irritating problem which I hope can be easily solved.
I've got 3 machines running over a wireless network. Machine A is my machine, and is connected to the wireless router by cable. It's running XP pro. The other 2 machines, B and C, are connected by wireless USB doobries, and are both running XP home. B and C are the kids machines, and all in the family have their own user names on B and C. On machine A, there's only me set up as a user (apart from the administrator profile in case its needed.) My login name and password are the same on all 3 machines. There's no problem in connecting to the internet from any machine.
From machine A, I can see the shared files on the other 2 machines, and can do what I want on the shared drives and directories. Whilst I can see machine A from B and C, anytime I try to do anything on the shared directories, I get a message saying I can't log on.
I've been through help and searched google to no avail. I suspect that its something to do with the settings of Machine A. Can anyone tell me what to do or point me in the right direction?
Thanks in advance
