How do I create a DHCP scope in Windows 2000?

A. A DHCP scope is a range of addresses that can be assigned to clients and can also optionally provide information about DNS servers, WINS etc.

DHCP scopes are configured using the DHCP MMC snap-in as follows:

  1. Start the DHCP MMC snap-in (Start - Programs - Administrative Tools - DHCP)
  2. Right click on the server and select New - Scope from the context menu
  3. The scope creation wizard will be started, click Next
  4. Enter a name and comment for the scope. Click Next
  5. Enter the address range to use, for example from to (remember the host part cannot be 0). Also enter the subnet mask as either the number of bits used or the actual mask, e.g. 24 is the same as Click Next

  6. You can specify addresses to be excluded either by range, e.g. to and click Add, or just enter a Start address and click Add, e.g. to exclude a single address. Click Next
  7. You can now configure the lease time for the address. Setting too large will mean you will lose the use of addresses if the client machine is inactive for long periods of time, too short and you will generate unnecessary traffic renewing the address. The default 8 days is fine. Click Next
  8. The wizard gives the option to configure the most common DHCP options. Select Yes and click Next
  9. Enter the address of the gateway, and click Add. You can enter several. Click Next when all are entered.
  10. Enter the DNS domain, e.g. and the DNS server addresses. Click Next
  11. Enter the WINS server addresses and click Add. Click Next
  12. You will then be asked if you wish to activate the scope. Select your answer and click Next
  13. Click Finish to the wizard

The new scope will now be listed and the status as either Active or Inactive.

If you selected to not activate the scope it can be manually activated by right clicking on the scope, select 'All Tasks' and select Activate. The activation is immediate. Likewise you can deactivate by selecting deactivate
