Chapter 4: Windows Disaster Recovery

Repairing a Windows NT 4.0 Operating System Installation

This section explains how to use NetWorker software to create a Windows NT 4.0 Emergency Repair Disk (ERD), and how to use the ERD to repair a damaged Windows NT 4.0 operating system installation.

To repair a Windows NT 4.0 operating system installation requires:

• Windows NT 4.0 Setup Disks (three disks)

• Windows NT 4.0 installation CD-ROM (same version that was installed prior to the disaster)

• Windows NT 4.0 Service Pack (same level that was installed prior to the disaster)

One of the following:

– A current Windows NT 4.0 ERD for the computer you are recovering

– The NetWorker backup or clone volume that contains the most recent REPAIRDISK save set for the computer you are recovering

• The Administrator account password for the computer you are recovering (required only if you are repairing the registry or system state)

If you do not have a current ERD, see “Creating an ERD from the REPAIRDISK

Save Set” on page 57.

If you have a current ERD, see “How to Use the ERD to Repair the Windows

NT 4.0 Installation” on page 59.

Creating an ERD from the REPAIRDISK Save Set

If you do not have a current ERD for the computer you are recovering, you can create one using either the NetWorker User program or the <NetWorker_install_path>\bin\recover.exe command.

Because the operating system of the computer you are recovering needs repair, to create an ERD you must use a different NetWorker client computer to perform a directed recovery of the REPAIRDISK save set. Before you begin the directed recovery, ensure that:

• The computer you will use to recover the REPAIRDISK save set is a

 

functional NetWorker for Windows client, connected to the NetWorker

 

server you will use for the recovery.

• The Client resource for the computer you are recovering includes in its

 

Remote Access List the NetWorker server you will use for the recovery.
