Re: DHCP Reservations

It is not that easy as you describe. One problem that you will have is lease
time. By default it is 8 days and if one of your current servers fail and
you switch to the other it will start giving out IP addresses that could be
already leased out since it doesn't know what was leased out already...

What you could do is have both systems running at the same time. Let say you
are using IP addresses ranging from 192.168.1.0 - 192.168.1.255 with 24 bit
subnet mask.
Give server 1 following range 192.168.1.1 - 192.168.1.150 and the other one
192.168.1.100 - 192.168.1.255. I know this two ranges overlap but this
overlapping part (192.168.1.100-192.168.1.150) can be used for static
assignment - but you will have to manually create these reservations (enter
MAC address on both servers and corresponding IP address from this
overlapping range).

You could also configure DHCP on cluster - but I know it gets more expensive
that way.

Hi,

I am in the process of installing our new Primary Server (W2003SP1) to
initially run alongside our existing machine, and eventually take the
majority of the load.
I have setup DHCP and have both servers showing on the MMC. I currently
only
have reservations on the old server, which I would like on the new server.
Do
I have to manually re-enter the reservations or can I transfer them
across??

Also, in order to avoid IP conflicy, I am going to unauthorize the old
server and force clients to use the new server. In case of system failure,
all I would need to do is authorize the old server and hopefully this
would
supply IP's to the clients - does this make sense to anyone other than me
??!!

Thanks in advance.
