What's the function of the OS-X server in this network? It doesn't seem like a good fit. Manca - This whole thing sounds like really bad plan. If you're keeping Exchange, you probably want to keep Active Directory. And if you want to keep Active Directory, you want Active Directory to also be both the dhcp and the dns server, so that computers joined to the Active Directory domain will do name resolution correctly.
If you really want to convert to an OS X-based environment and if you have any number of windows PCs, this is a questionable move , you should ditch exchange as well and use the OS X's mail server. Joel if you're planning on keeping Exchange you don't "probably want to keep Active Directory", Active Directory is required.
If you take Active Directory away from Exchange or try to move it on to the Exchange server for that matter it will burst into flames. Show 3 more comments. Ben Pilbrow Ben Pilbrow 12k 5 5 gold badges 34 34 silver badges 57 57 bronze badges.

The period of validity is called the DHCP lease time. To avoid impacts of the DHCP server not being available at the end of the lease time, clients generally start renewing their lease halfway through the lease period.
This renewal process ensures robust IP address allocation to devices. Any device asking for a new IP version 4 address at arrival on the network and not receiving an answer will use automatic private internet protocol addressing APIPA to select an address. These addresses are in the network range There are four key DHCP usage scenarios: 1. A DHCP server can act as a primary or a secondary server.
To be a primary server, it must have a range of IP addresses for which it is responsible. When a DHCP server is added to a network that already has a primary DHCP server, the new server can be configured to provide primary and secondary service, or secondary service only.
If the server is configured for both services, both servers can perform the duties of a primary server, they can give out IP addresses as long as each is primarily responsible for a different IP range. Each server can act as a secondary server for the other, by confirming existing configurations supplied by a primary server when the primary server is unable to respond to requests for confirmation. Every primary server automatically acts as a secondary server.
A DHCP server's range of IP addresses is specified during the installation and configuration of the software on the server. As a primary DHCP server, the server can give out an IP address to a client requesting a new configuration from the range of IP addresses for which it is responsible.
When a client asks for confirmation of its existing configuration, the server responsible for that client's IP address confirms the configuration. Acting as a secondary server, it can confirm configurations that were supplied by another DHCP server on the network.
