I am trying to build a machine but I see the following error:

Task Sequence: <name> has failed with the error code (0x00000001). For more information, please contact your system administrator or helpdesk operator.


This message is displayed because the Task Sequence had an issue in locating/ loading a file. Make sure no-one is editing the Task Sequence or updating any files it references then power off the machine and try rebuilding it.
