Bare metal recovery of Windows NT with ADSM
Draft

Introduction

The need for bare metal recovery arises when a computer has been destroyed or
has suffered a
catastrophic disk failure. All known methods of using ADSM for bare metal
recovery of
Windows NT involve two copies of the operating system: the one that is
restored from the
ADSM server and the one used to run the ADSM client. This is probably best
done by having
a separate recovery partition defined. However, few if any of the TJU servers
have such
recovery partitions configured at this writing. In the absence of a recovery
partition, the
procedure outlined below puts the two copies of Windows NT in different
directories within a
single partition.

Recovery system requirements

Each replacement Windows NT must have the following hardware features:
* A CD-ROM drive.
* Enough spare disk space for a second copy of Windows NT and a second copy of
the
ADSM client software in addition to the space required to perform restore
process.
* A network interface capable of supporting IP connectivity.
* NT local administrator account and password information.

Preparations

The following materials and infrastructure must be available to support the
process:
* Windows NT installation diskettes and CD-ROM media.
* DOS bootable floppy disk and Windows NT service pack 3 CD-ROM.
* CD-ROM media or a file server containing ADSM client software for Windows
NT.
* An up to date listing of the sizes of disk partitions on the original
system.
* An ADSM server with backups of the files on the original system.
* Installation instructions for installing Windows NT on a different hardware
platform.

The Process

1. Install Windows NT in the \winntemp directory, using a 2 GB FAT disk
partition {D:}.
2. Configure the Administrator account with no password.
3. Create the original disk partitions-similar to the original server.
4. Install the same service pack level as the original server.
5. Reboot server using the DOS bootable floppy.
6. Make a temp directory:  D:\jrtemp.
7. Copy D:\winntemp\system32\config\*.* to D:\jrtemp\config
8. Copy D:\winntemp\system32\hal.dll to D:\jrtemp
9. Reboot server into NT; Copy the C:\boot.ini to D:\jrtemp.
10. Install ADSM client software in the /adsmtemp directory.
11. Edit the options file and set the IP address of the ADSM server.
12. Restore the files originally in the partition from the ADSM server,
exclude the C:\boot.ini
file.
13. Edit the D:\jrtemp\boot.ini file to point to the C: drive and the WINNT
directory.
14. Copy the D:\jrtemp\boot.ini to c:\.  Overwrite the existing file.
15. Copy the D:\jrtemp\config\SYSTEM.*  to C:\winnt\system32\config.
Overwrite any
existing files.
16. Copy the D:\jtemp\config\*.EVT to C:\winnt\system32\config.  Overwrite any
existing
files.
17. Copy the D:\jrtemp\hal.dll to C:\winnt\system32.  Overwrite the existing
file.
18. Copy the contents of the C:\adsm.sys\registry\system\machine\*.* directory
into the
C:\winnt\system32\config directory, where system is the system name.
19. Copy the file C:\adsm.sys\registry\system\users\default into the
C:\winnt\system32\config
directory.
20. If a user username was logged on locally when the last ADSM backup was
run, copy the
contents of the C:\adsm.sys\registry\user\username directory into the
C:\winnt\profiles\username directory and rename the username000 file as
ntuser.dat and
the username000.key file as ntuser.dat.log.
21. Reboot the system.
22. Restore the contents of any additional partitions.
23. Delete the \winntemp and \adsmtemp directories {D:}
24. Remove any/all network interface cards from the ADAPTERS section of the
network
folder in the Control Panel.
25. Reboot the server and add the network interface card that is present in
the server.
Configure the IP address-supplied by SunGard.
26. Convert the {D:} drive from FAT to NTFS; Type convert d: /FS:NTFS
