Changing Scope Properties

The subnet identifiers and address pool make up the properties of scopes. You can change the properties of an existing scope.

You cannot exclude a range of addresses that includes an active lease. You must first delete the active lease, as described in "Managing Client Leases" later in this chapter, and then retry the exclusion.

To change the properties of a DHCP scope

1. In the DHCP Servers list in the DHCP Manager window, select the scope for which you want to change properties, and then choose Properties from the Scope menu.

– Or –

In the DHCP Servers list, double-click the scope you want to change.

2. In the Scope Properties dialog box, change any values for the IP address pool, lease duration, or name and comment as described earlier in "Creating Scopes" or in online Help. You can extend the address range of the scope, but you cannot reduce it. You can, however, exclude any unwanted addresses from the range.
3. Choose the OK button.
