DHCP Backup server...

Hello all I'm trying to setup a backup DHCP server in windows 2000. I installed active directory on this backup server also. Now my ? is that I'm trying to basically synchronize all the DHCP info to a this new backup server as smooth as possible with no conflicts. I've already installed the DHCP service and now I want to set this box up as a backup. I done this with DNS and it was pretty simple I just had to provide the installation wizard the correct info about the primary server and also let it know that DNS2 is a secondary box. Now I right clicked on new scope on dhcp2.domain.com(backup) and selected new scope but I feel that if I go on with the installation it will make the network think that dchp2 is now the primary. I know for a fact that the company consultant is waiting for me to make a mistake and also waiting for my call so he can charge us a fat amount. HELP!

Why not just set it up the way you want it, just don't authorize the server to disperse IP addresses.  Granted you have to manually authorize the server to act as a DHCP server when the primary goes down, but that doesn't take but a few minutes.
If this is a good enough idea just send $800/hr - 4 hr minimum!  :-)

ocon the I know I can do that but the reason I want to setup as a synchronization is because this is how we had our Network setup and I just want to keep it like it was. Luckily our backup crashed not the primary. Also do you guys think I should do these modifications in the evening when no one is around? Thanks.

1) make sure your primary is backed up.

2) Make sure your secondary is also.

3) Make the changes. It should not make any difference to the users, since most will not be rebooting and getting new DHCP info anyway.

I hope this helps !

What is your lease time set to?  You might consider using DCHPEXIM from the 2000 RESKIT to export the DB.  It is much simpler than the process cited in most of the Q articles.  The only issue is that it does not seem to have any switches or automation.

Jasan, before you get yourself into a bind, read this document. It will explain how to setup the backup server, especially with respect to name ownership etc.

there are a few options in how to do this.  do you just want the backup DHCP to be on standby without leasing to any client and kicks in when the active one fails?  If this is the case, then MS Cluster service is a great way of doing it.  However, you'll need to be familiar with how clustering works and have all the required hardware - ie: shared disk.
You can also copy the db from 1 DHCP server to the other as geoffryn had mentioned.  you should also write a script to periodically synchronize the db's.
If you also want it to lease to clients, then you can use the distributed scopes technique.

good luck.
