I would just like to make a note that tricked me, i feel other may benefit from having a headsup, and maybe could even help me resolve this issue.
we have just upgraded from 2000 server to 2008 the process is as follows:
download and run DHCPEXIM.EXE on your 2000 server, follow the prompts and export to a file, I never ticked the box to disable the scopes as i think this may have mean't if i couldn't do a successful upgrade i would have to re-enable over 150 scopes one at a time.
once you have this file you can remove the DHCP Server from the domain (if your using the existing ip address / hostname )
you can then goto your DC's and authorise the new server to be the DHCP server.
login to the 2008 server
assuming you have already installed the dhcp service without any scopes you can run the following to import the file you created earlier.
netsh dhcp server import c:\yourfile
this can take some time 150 scopes took about 5 mins for me.
once this command completes you can then right click the dhcp scope and authorize if it hasn't already done so by it's self.
here is the important bit that caught me out
if you admin the dhcp server remotely with the windows admin tools note that your tool will no longer display the reservations (altho they are there ! )
if you look directly on the server your see all of them but with the remote tool they are hidden, you can even add new ones which will then show up for that current admin session but if you close the app and then reopen it there gone.
if anyone knows how to fix this i would like to know.
