SUMMARY
=======
The Windows NT 4.0 Server and Workstation compact discs include a utility called
Rollback.exe. Rollback.exe was designed to help computer manufacturers
preinstall Windows NT 4.0, and allow end-users to do the final configuration
according to the desired role of the computer. Running this utility will remove
all registry settings on a system and bring it back to the end of the Character
Based Setup portion of the Setup program, effectively undoing everything
configured by the GUI portion of Windows NT Setup.
WARNING: Do not run this file on a production system! There is no way to recover
information erased by running this utility, so anything stored in the registry
will be lost. This includes user account information, protocol bindings,
application settings, user preferences, etc.
MORE INFORMATION
================
If you run Rollback.exe on a production system there is no warning that
Rollback.exe removes all system registry entries. Therfore, after you run
Rollback.exe there is no system to rescue or to restore as the registry and the
Setup.log file no longer exist.
The only fix to this problem is to restore the entire system from a current tape
back up. Emergency Repair Disk does not restore the system as it requires the
Setup.log and specific registry components to be present.
Rollback.exe is on the Windows NT compact discs in the following directory:
Support\Deptools\<system>\
