Missy, would love to...
but given a significant lack of documentation on installed
apps / shares an upgrade seems the better part of valour in this instance

Sounds like you're making something fairly
simple into something rather convoluted. I'd simply rebuild the boxes
and join them to the new domain.

Subject: [ActiveDir] Nt4 domain
controller upgrade to Windows 2000
Apologies if this one has been around before
but ..
as subject i am looking to acheive the upgrade of a whole load
of NT4 backup
domain controllers to Windows 2000.
it is preferable
to use an upgrade method (as opposed to new install) -
based on a number
of installed applications / services (dhcp, wins, lpr
server).
it
is also intended to change the domain membership of these DC's in
the
same process. the observed behaviour is that the Windows 2000 setup
routine
detects its configuration as a DC and generates a "red" warning
in a system
compatibility report stating that the PDC should be upgraded
first.
presumably the setup routine must do some sort of query
against the PDC to
determine its OS version ??
the domain from
which these DC's are intended to be migrated is in fact a
NT4 domain, and
this seems to be critical to the continuance of the
setup
routine.
is it correct that there is no option for the
existing domain membership to
be modified in this setup routine
??
it seemed to me that the dcpromo routine that initiates at first
logon when
Windows 2000 starts would be flexible enough that if the
administrator so
decided to remove any exsiting security information from
the original NT4
domain and replace it with the information from an
administrator specified
domain ??
if this is the case then the
available options (given that the upgrade of
the PDC to a production
domain is by far the least preferable) need to be
evaluated;
is it
a "supported" operation to take the BDC offline from the network,
promote
it to PDC (merely to allow the setup routine to proceed) which
presumably
would complete given that the system would not detect any - this
begs the
question as to the checks that a BDC promotion goes through to
complete -
is it merely the non-detection of an exsiting PDC or is there a
bit more
sophistication ??
from here then once the system is running Windows
2000, the dcpromo process
can be stopped, and reinitiated once the
computer is joined to the network
once again as a Windows 2000 member
server, and joined to a new domain ?
otheriwse it seems to me that
the only way of proceeding is to use the
"clean installation" method and
reinstall all applications / services.
on this tack, it seems to me
potential issues with the restore of a DHCP
server configuration (backed
up by taking a copy of the relevant NT4
registry key) to a Windows 2000
DHCP server - is this a supported operation.
I will be very
appreciative of input from the newsgroup on this
one
