Batch File Example
The example below shows how to check for a specific error level using a DOS Batch file:
@ECHO OFF
DFC.EXE get /isfrozen
IF Errorlevel 5 GOTO Error5
IF Errorlevel 4 GOTO Error4
IF Errorlevel 3 GOTO Error3
IF Errorlevel 2 GOTO Error2
IF Errorlevel 1 GOTO Error1
IF Errorlevel 0 GOTO Error0
:Error5
Echo Errorlevel 5
Goto END
:Error4
Echo Errorlevel 4
Goto END
:Error3
Echo Errorlevel 3
Goto END
:Error2
Echo Errorlevel 2
Goto END
:Error1
Echo Errorlevel 1
Goto END
:Error0
Echo Errorlevel 0
Goto END
:END
Actions can be placed between the
ECHO Errorlevel #
statement and the
Goto END
statement for
each of the detected error levels. To use this Batch file to automatically Thaw a Frozen workstation, the
following section of the Batch file would have to change to the following:
:Error1
Echo Errorlevel 1
DFC.EXE password /BOOTTHAWED
Echo
Goto END
This section contains the
actions that should be
performed for each Errorlevel.
This section checks the
Errorlevel that DFC provides to
the operating system.
