There’s a bug in Windows Vista (who’d o’ thunk?). If you enable file sharing, then attempt to add a user to the share using this window:
you may get the error “Uable to locate user”. This is caused by the user name and login name being different. You’ll need to make them both the same to add the user. After you add them, you can change the user name and login names to be different.
