I have a Windows 2003 network with about 50 client stations. I have
two servers running DHCP:

server01 has a scope of 192.168.2.10-x.x.x.60
server02 has a scope of 192.168.2.61-x.x.x.115

I do very little on the network as far as adding new stations,
installing NICs, etc.

My question: Is this a good way to setup DHCP redundancy or am I
missing something?

Hello Nick,

This is ok, but think also about redundant DNS server (Active directory integrated
zones) and also have more then one global catalog server.

Best regards

I use the full range in both scopes and then use Exclusions to control what
is given out.

Full range and then use exclusions? Can their be conflicts between the
two? Are the lease expirations different?

What you do is to assign the same range to both servers, then exclude
non-overlapping ranges between the two. For example, set up both servers to
assign addresses in the 192.168.0.x range, then on the first server exclude
192.168.0.1-127 and on the second server exclude 192.168.0.128-254 so that
no address can be given out by both servers. In the event one fails the
other will continue to hand out addresses.

No. That is what the Exclusions are for.
I want the Scopes to be fully configured with the full address range and be
identical other than the Exclusions.

If one DHCP fails I can just alter the Exclusions on the remaining one and
it can take over everything.
