Windows Serrver 2003 DHCP Question

Hello Experts,

I have some DHCP questions I am sure have an easy answer... so here goes. We currently have two Windows Server 2003 DHCP servers. Our second server is configured as follows:

Address Pool: 10.1.9.1 - 10.1.9.255 Disribution
                        10.1.9.1 - 10.1.9.11 Exclusion

The first server is as follows:

Address Pool: 10.1.3.1 - 10.1.4.255 Distribution
                        10.1.7.X - 10.1.8.X Reserved by MAC address

Here are my thoughts...

I have set up the second DHCP as a failover in case the first DHCP fails.

1. Would this be a sufficient setup in an environment where we only need about 200 clients?
2. How can I get a good failover for my reservations from the first server, maybe by entering the same reservations on the second???
3. Our first DHCP server just recently started to not automatically start when the server is rebooted. It can be started manually and it works fine after that. Any ideas on what to try that would fix this?

Thanks!!!

1. Your new server has enough addresses for 243 clients.  So if you are under 200 then you will be fine.

2. Yes, set the same reservations on the second server

3. Are there any errors logged in the event viewer from the DHCP service or Service Control Manager describing why the DHCP server can't start?

Thanks!

I there any way to import those reservations to the new server or do I have to enter them all manually? There were some DHCP errors yesterday they are 1004, 1010, 1016, 1014, and 1008.

The only way I can think of to import your reservations would be to open your primary server in dhcp management then RC and backup.  Then go to the new server and RC Restore using the backup from the other server.  You would then have to remove the scopes that were brought in from the primary and create the scopes you want for the secondary.

As far as the DHCP errors go there are a lot of reasons why you might be recieving these errors.  Check out www.eventid.net and type in your event ID and the source to see possible solutions to those errors.
