Figure 124. Encryption Components in the Service Pack. If you use 128-bit encryption,
you should click on
Cancel
in order not to overwrite the encryption files.
If you choose not to install the encryption components, you will gain some
security benefits in a secure C2 environment. Either choice does not have any
impact on the functionality of your server.
C.2 Emergency Repair Disk (ERD)
If it is necessary to use the Windows NT ERD to repair your Windows NT system
after you apply the service pack, you will need to re-apply the service pack after
the repair has completed.
The ERD repairs your system by restoring your original Windows NT Setup
information, which subsequently changed, thus resulting in the need to re-apply
the service pack. After the repair has completed, simply follow the above
installation instructions to re-apply the service pack.
It is
advisable
to update your ERD after you make any changes to the system.
You can do this by running
RDISK.EXE from the \WINNT\SYSTEM32\ directory.
C.3 Adding New Components to the System
If new software or hardware components are changed or added to your system
after you have applied the service pack, it will be necessary to re-apply the
service pack. This is because the files taken from the original Windows NT disk
set may not be equivalent to the files on the service pack disk set.
It is not possible to install new components directly from the Service Pack media
(such as a new keyboard or printer driver); they must be installed from the
original product media.
Don′t Forget!
Remember to recreate the emergency repair disk.
