We currently had a Windows 2003 Server setup to be our Active Directory, DNS, and DHCP server. We also have another Windows 2003 Server that is our primary file server. Both are Virtual Machines running in an ESX4 cluster of 3 VMware hosts.
We recently promoted our file server to be a secondary Active Directory Domain Controller and also installed DNS on it so we now have a backup domain controller and DNS server.
Does it make sense to have the file server also be a backup/secondary DHCP server as well, or is that not necessary? Or is it even possible? What happens to the workstations that reboot if the DHCP server is down and there isn't another DHCP server to process the DHCP requests?
Thank you in advance for any insight provided.
