Using windows XP pro. on a 2 computer home network. Was using simple file sharing and everything was working fine for awhile. Then started getting file accesss denied with different files. clicked off simple file sharing and tried to change owner but would not let me and could not find owner. backed up all data and reformated hard drive on 1 computer reloaded all software but when try to bring data backin from backup access denied and can not change owners. Anybuddy run into this problem. Any help would be greatly appreciate. also can you go from simple file sharing to not simple file sharing and back?
