In my mind, the MS Recovery Console is the key to achieving successful
restores back to dissimilar h/w in the Wintel area. After installing
your vanilla MS OS (that is to be restored over), you need to take a
copy of the OS files that are specific to your h/w. Then, if they are
overwritten with different versions by your restore, you can put them
back with the RC upon reboot.

These files can be found in Device Manager--> Computer and then under
the driver details of the Properties of your processor(s).

For Windows2000, they are as follows
c:\winnt\system32\hal.dll
c:\winnt\system32\kernel32.dll
c:\winnt\system32\ntdll.dll
c:\winnt\system32\ntkrnlpa.exe
c:\winnt\system32\ntoskrnl.exe
c:\winnt\system32\win32k.sys
c:\winnt\system32\winsrv.dll

For Windows2003, they are as follows
c:\windows\system32\hal.dll
c:\winnt\system32\ntkrnlpa.exe
c:\winnt\system32\ntoskrnl.exe

If after you complete the restore of your system drive and you reboot
and get a blue screen or worse, all is not lost. The Microsoft Recovery
Console is an extremely useful tool. From the RC, you can copy the above
original files from a floppy or the root of the system drive to the
system32 directory. Also, the RC will enable you to disable devices or
services on boot.

One important point to note, the RC requires the LOCAL administrator
password to be entered before it can be used, therefore ensure that you
know the local passwords to all your machines.

The following IBM Technote is also very useful for Wintel system
restores

Above all else, the key to restoring back to dissimilar h/w is practice.
Where possible, try to trial restore as many of your Wintel systems back
to unlike h/w. I know it is obvious, but it is far easier to solve any
arising issues in a DR trial environment, than at 3am with somebody
looking over your shoulder, asking every 5 minutes when will it be ready
?

>What kind of system are you concerned with?

I'm looking for some basic info on all platforms anyone has experience
with,
Windows being the biggest concern. After hearing some remarks this
morning
in a meeting concerning bringing back a server from scratch, and how
long it
took, I'm flabbergasted. Then again nobody called me to ask for help
either.

To add to this are there any issues anyone is aware of for servers that
have
been virtualized but still use TSM for their backups? Would the process
be
the same?

Thanks,
