There are some Microsoft white papers on this topic that tell you how
to delete the hardware spec files and force NT to do a fresh
autodetect of hardware. I have it but haven't tried it. Eric
How to Restore a Backup to Computer with Different Hardware Article
ID: Q139822
The information in this article applies to:
Microsoft Windows NT Workstation versions 3.5, 3.51, 4.00
Microsoft Windows NT Server versions 3.5, 3.51, 4.00
SUMMARY
This article explains how you can restore a tape backup from one
computer to another computer with different hardware, and maintain
user accounts and working environment. This procedure may be needed if
there is no backup domain controller or fault tolerance implementation
on the network and the primary domain controller is down for some
time.
A backup set is intended to be used as a disaster recovery utility to
maintain your system by backing it up and restoring it to the same,
not a different computer. When you restore to a different computer you
may encounter problems, due to hardware differences between the two
computers.
This procedure is not recommended by Microsoft and therefore is not
supported. Microsoft makes no warranty, implied or otherwise,
regarding the performance, stability or reliability of this procedure.
MORE INFORMATION
NOTE: If you need to only change the primary hard disk and controller
while maintaining user accounts and desktop settings, please see the
following article(s) in the Microsoft Knowledge Base:

TITLE : Changing Primary Disk System After Installation
To restore a tape backup from one computer to another computer with
different hardware, and maintain user accounts and working
environment:
1. From the original computer you need a tape backup of the registry
and all
other files you want to transfer.
2. Partition and drive information should be set up the same as the
original
computer. However, the primary partition should be a FAT partition
and
initially Windows NT should be installed onto a FAT partition (it
can be
converted later). Use the same computer name and domain name as the
computer
that is being replaced.
3. Create a directory off the root called CNFGTEST. From the backup
set restore
the Registry (%SystemRoot%\system32\config directory) to
C:\CNFGTEST on the
hard drive.
4. Delete SYSTEM.* and *.EVT files from C:\CNFGTEST.
NOTE: These files must be deleted in order to remove hardware
specific
information.
5. Boot to DOS and copy the remaining files from C:\CNFGTEST to the
current
%SystemRoot%\system32\config directory.
NOTE: You cannot replace SAM or Security hives while Windows NT is
running.
6. Reboot the computer and make sure that everything is functioning in
Windows
NT. When you restart user accounts should be in place.
7. If you use TCP/IP with DHCP and/or WINS, you can restore the
%SystemRoot%\SYSTEM32\DHCP and the %SystemRoot%\SYSTEM32\WINS
directories. It
may be necessary to reestablish the DHCP scope.
8. The %SystemRoot%\SYSTEM32\SPOOL and %SystemRoot%\SYSTEM32\REPL
directories
can now be restored. If you were using TCP/IP printing, printer
queues will
have to be re-created and IP addresses reassigned.
9. Convert to NTFS if the original install was NTFS. To replace data
with
permissions you must convert to NTFS. To convert the file system to
NTFS,
type the following from the MS-DOS Command Prompt:
convert <drive letter> fs:ntfs"
Next, restore the user data.

Does any one have any hints on using ADSM to restore to different Vendor
machine. We have a NT 4.0 operating system that was backed up from an IBM
Netfinity server and trying to restore to a Compaq server.
Thanks,
