I used:

netsh dhcp dump >C:\dhcp.txt

Recreatse the scope on the new server. Then:

netsh exec c:\dhcp.txt



MS Print Migrator is great.  I have a dns entry for the print server ,
so when I change servers I merely change the name in dns. It took while
for users to get mapped correctly but it's great. (Also  dns entry for
home dirs and profiles paths. I use dfs for data)

Sure thing Glenn.


1:It is possible to move dhcp between same OS servers, I think you just
need to copy the Database from old to new.


2: With regards to printers, yes you can migrate them over with
PrintMigrator 3 from Microsoft. It would be a lot easier if the
servername would remain the same. However if it doesn't, I have included
a little script that should change the client-side for you. just rename
the extension from .txt to .vbs, then probably implement like I did
through script. I had this running for about 1 week, then disabled it.

        Yes, but I would move the FSMO roles first.

        Yes, that is what I do.  Use the /sec option, or the /mir option
if you prefer.


        "Is there a way to move my DHCP settings?"

        Same OS on the old and new server?  If so, yes.  But I have
never had much luck with this.

        Unless you have a huge number of reservations, I would manually
create the new scope.  But first, I would set the old scope to have a
ridiculously low lease time, and wait until everyone has refreshed their


        I.e., if you currently have a three day lease time, then 1.5
days before you intend to activate the new DHCP server (give yourself AT
LEAST 50% of the old lease time, if not more) change the lease time to
something like an hour or two.


        I usually use this as an opportunity to re-do my reservations
anyway, so that printers are all contiguous, etc...


        "Is there a way to move print server printers?"

        Not sure what you mean... unless the server is going to have the
same name (which is impossible given your steps to upgrade) you are
going to have to re-map your clients printers anyway.

        Subject: [windows2000] Replacing DC with another DC

        We are a small school with only one server.  I just want to make
sure I do this correctly.  I'm replacing my DC with a new machine.


        1) Configure new server

        2) join domain and promote to a DC

        3) Demote old DC


        Can I test the new DC by just shutting down the old DC prior to
demoting?  I would hate to lose all the student login information.


        Can I use robocopy.exe to move all the folders with permissions
to the new box?


        Is there a way to move my DHCP settings?


        Is there a way to move print server printers?


        Any help would be appreciated.
