Download your free Network Device Monitor. Guy's Review of Computer Tools. Perhaps you have never given the DHCP database a thought. Well the time may come where you need to backup, reconcile or compact the DHCP database.
At the very least, I expect you will want to check your lease statistics. I just hope that you are not afflicted by this blind spot. Display Statistics is available at both the server and the scope level. See the screen shot to find the Display Statistics… menu. Network C — Windows Server R2 x It can change according to your requirement. Click next to continue 8 Then it will give brief description about DHCP server role and click next to continue.
What about moving many w2k3 dhcp server scopes to just 1 w dhcp server. Keep repeating the same process and the scopes append? Specifying the IP address range of a scope requires some knowledge of subnetting. Each scope in a DHCP server holds a pool of IP addresses to give out to clients, and the range of IP addresses must be within the allowed range of the subnet that you specify on the subnet mask field.
For simplicity we entered a classful, class C IP address range from Notice that the range encompasses the IP address of our server, the DNS servers and the default gateway, meaning that the DHCP server could potentially assign a client an IP address that is already in use! Do not worry -- we will take care of that later. Specify IP addresses to exclude from assignment. For the Start IP address , enter Certain network devices, such as servers, will need statically configured IP addresses.
The IP addresses may sometimes be within the range of IP addresses defined for a scope. We have the opportunity here to define those IP addresses that are to be excluded.
We specified IP addresses Specify the lease duration for the scope. Verify that Days is 8 and click Next. The lease duration is how long clients should keep their IP addresses before having to renew them. There are a few considerations at this point.
If a short lease duration is configured, clients will be renewing their IP addresses more frequently. The result will be additional network traffic and additional strain on the DHCP server.
On the other hand if a long lease duration is configured, IP addresses previously obtained by decommissioned clients would remain leased and unavailable to future clients until the leases either expire or are manually deleted.
Additionally if network changes occur, such as the implementation of a new DNS server, those clients would not receive those updates until their leases expire or the computers are restarted. In an environment where computers are often moved and replaced, such as a wireless network, you would want to specify a short duration since a new wireless client could roam within range at any time.
