I tried without success to prevent the password prompt (i seem to vaguely remember something about a file deletion being necessary) by setting the Users control panel applet to not have any users.
I noticed also that the Network applet was set to use a workgroup, but it didn't seem to like my removing this either. Similarly i noticed that something called 'Microsoft Family Logon' was set in the networking applet. Attempting to remove this just caused something like 'The network is incomplete' or some such to appear.
Looing through system help on these issues was a waste of time. Can someone supply the missing help please?
