Hi

I have 2 servers (PDC and BDC) in a single NT4 domain. The PDC is
currently our only DHCP server. I want to enable DHCP Server on the BDC
for redundancy, it is currently installed but the service is disabled
at startup.

I thought I would start the DHCP Server service on the BDC then add the
total scope and configuartion options that match the PDC. I would then
add the exclusions, following MS's 80/20 design rule, where I would
exclude the first 80% of IPs from the scope of the BDC and exclude the
last 20% of IPs from the scope of the PDC.

Can I do this whilst PCs are connected to LAN? How do I switch over ?
Do I just configure it and let it get on with it or do I have to stop
and start DHCP Server services on both machines?

Any other pitfalls to watch for?

Thanks in advance

You don't have to restart anything. As long as the addresses
don't overlap you should be fine.
