unable to open DCE authorization file Explanation: The DCE$UAF file does not exist. The user will be asked if a new DCE$UAF file should be created. User Action: If a DCE$UAF file that you want to use exists in another directory, exit the DCE$UAF utility and SET DEFAULT to that directory or define the logical name DCE$UAF to point to the required DCE$UAF file and then restart the DCE$UAF utility.
