When you specify a secondary DNS server, separate the two IPaddresses by a space.Business Communications Manager automatically assigns the value for this parameter. If theIP address or subnet mask for the corresponding LAN interface changes, this value isoverwritten. Use caution when changing this value.WINS Server Allows you to specify the IP address of the WINS server.Business Communications Manager automatically assigns the value for this parameter. If theIP address or subnet mask for the corresponding LAN interface changes, this value isoverwritten. Use caution when changing this value.Default Gateway Allows you to specify the IP address of the default next-hop router.Business Communications Manager automatically assigns the value for this parameter. If theIP address or subnet mask for the corresponding LAN interface changes, this value isoverwritten. Use caution when changing this value.Lease Time Allows you to specify the time, in seconds, for an address assignment until the client’s leaseexpires.The default is 259200 seconds (72 hours).Scope Status Allows you to enable or disable the scope.The default is enabled.Note: If the IP address or subnet mask for a LAN interface changes, the system creates ormodifies the corresponding DHCP scope for the interface. This operation also involvessetting default values for some parameters. By default, Business CommunicationsManager sets the IP address of the corresponding LAN interface to the DNS Server,WINS Server, Default Gateway options of the scope. It also sets the lease time to threedays and creates a range of addresses for the scope. If the IP address of the LAN interfaceis in the lower half of the subnet, the address range set for the scope includes all theaddresses above the LAN interface address. If the IP address of the LAN interface is in theupper half of the subnet, the address range set for the scope includes all the addressesbelow the LAN interface address. By default, the scope is enabled.Note: When DNS is disabled in Business Communications Manager, the DNS Server boxmust be set to the IP address of a remote DNS server.
