Best way I can thing of is setup two separate scopes, and only
activate one.When you need to make the change,disable the first, and
enable the second.
Don't know how to do this on one box with a batch file, but with two
DHCP servers,you can simply run "net start "Microsoft DHCP Server" in
a batch file to start the redundant one, and "net stop "microsoft DHCP
Server" on the failed one. From the client IPconfig /renew (NT/w2k
clients) or Winipcfg /renew (9x clients)

Even easier might be an inexpensive CISCO switch or something that
handles the routing for you. That way you wouldn't have to mess with
the clients.
