As per another thread in this list, I too have identified this file HPBAFD.INI as the source of occasional loss of connection to my terminal servers. The application lockout apparently caused (in some manner) by this file usually occurs during a printing event. In addition, Veritas Backup Exec identifies this file as incomplete when trying to back it up. The file is always recreated when deleted and therefore required by the printing environment. If anyone else has seen this and discovered what it is for, a response would be appreciated. There is almost no other mention of this issue on the web.
