DHCP - W2K to W2K3 move

Hello

I am researching the article 325473 for this move and have some questions. I
would also appreciate anyone's input that may have already completed this
move.
OUr DHCP server are load balanced, in that they both have the same scopes,
but different IP ranges for leasing.

1. Certain items will not be imported via DHCPEXIM.
I cannot find the following information to verify: DHCP databae backup path,
Mulicast Scopes and BOOTP tables.

2. Step 2 of the article state to run jetpack from the command prompt. Is
this the right path? Jetpack resides under system32, not the dhcp folder. Is
using jetpack necessary?

3. Step 4 is a little confusing. After exporting, can't I just copy the file
(not sure which file?) to the target server and import via DHCPEXIM? Is this
file a text file? or DHCP.mdb. I see that it is reccomended to use netsh.

Thank you for your assistance.

If you are looking for W2k -> W2k3 migration, then "Dhcpexim.exe" itself can
not be used on W2K3.

The path is correct. "jetpack" utility resides in %windir%\System32, which
is present in default value of environment variable "PATH". The
"%windir%\System32\dhcp" folder is where "dhcp.mdb" resides. The "cd
%systemroot%\system32\dhcp" action is for "dhcp.mdb" sake and not for
"jetpack".

Yes, this is necessaruy to compact the DHCP database.

> 3. Step 4 is a little confusing.

Step 4 mentions "Disable the DHCP Server service on the server". The "DHCP
Server" service needs to be disabled to prevent DHCP Server from starting
after the database has been transferred.

Reason why you cannot use "Dhcpexim.exe" to import the database in W2k3 is
that "Dhcpexim.exe" is not supported in W2k3

Please note that DHCPExim.exe utility
(http://www.microsoft.com/windows2000...dhcpexim-o.asp)
is supported only on Windows 2000 Server or Windows NT Server 4.0.

Also note that if a database is exported on a Windows 2000-based computer
using DHCPExim utility and an attempt is made to import it on Windows Server
2003 using DHCPExim.exe utility, then DHCPExim terminates with the following
error message: "An error occurred. An attempt was made to load a program
with an incorrect format."

Please let me know if you need any further assistance.

First off, be proud that someone actually did a search before re-posting!

Anyway, can you jetpack the DB with the service running or is it 100%
necessary to stop this first?

My plan is to export the DB and test DHCP restores, so I WANT the server to
continue to give leases. I just want a copy of the DB for testing.

Are there known issues moving a DHCP database/config to a DHCP server in an
entirely different domain?

I don't think so. DHCP wouldn't know a Domain if it tripped over one.

That's about my thoughts on that, thanks =) Just checking if there was some
stupid hidden security thing.

Now what about jetpacking and doing the db export while the service is
running? Possible?

AD does have to "authorize" the DHCP to give out addresses before it can do
it, but that is the only connection I can think of.

Never even heard of "jetpacking". I never export DHCP,...I just configure
the new one indentical to the old one,..power off the old one, start up the
new one. I intensionally never create large numbers of "Reservations" so
that building a new one is easier to do. If there are a large number of
Reservations, then you should have just statically assigned them in the
first place and not even use DHCP.
