Reset password to blank

Note: PI Base Subsystem must be shut down for this command to succeed. Also note the path argument requires a trailing \ character.

The administrative account is piadmin. To reset the piadmin (userid #1) password to blank:

1. Navigate to the PI\adm directory.

2. Type:

   pidiag -udf path

   This command is useful when the piadmin password is lost. For example:

   e:\PI\adm>pidiag -udf e:\pi\dat\
   The administrative password has been successfully reset.

Following this operation, the piadmin password can be set to any given string using the pisetpass utility.
