  • GPO Preferences included in Windows 2008 server helps you eliminate logon scripts

    Group Policy preferences are made up of more than 20 new Group Policy client-side extensions (CSEs) that expand the range of configurable settings in a Group Policy object (GPO). These new preference extensions are included in the Group Policy Management Editor window of the Group Policy Management Console (GPMC). The kinds of preference items that can be created by using each extension are listed when New is selected for the extension. Examples of the new Group Policy preference extensions include the following:

Dynamic Host Configuration Protocol (DHCP) server services are used to provide automated IP configuration services for computers. However, traditional DHCP services are prone to outages and failure because the database that contains the DCHP lease information is stored on only one computer. If the computer fails, the DHCP lease database is inaccessible and computers are unable to renew their DHCP leases.

In Windows Server 2008 R2 and Windows 7, the DHCP Failover feature has been included to help mitigate IP configuration outages due to DHCP server failures. The DHCP Failover feature is an implementation of the DHCP Failover protocol, which is an Internet Engineering Task Force (IETF) draft.

With DHCP Failover, two computers providing DHCP Server services synchronize DHCP lease information. One computer is designated as the primary DHCP server and the other as the secondary DHCP server, which is similar in concept to the primary and secondary Windows Internet Name Service (WINS) servers.


This will cause switch flooding by sending the packets to every port in the switch. But if you are using a Network Hub unicast will work for you.


Is the way to deploy NLB in switches.  With multicast, each NLB node effectively has two MAC addresses: a physical MAC and a multicast MAC.  Switches typically do not associate ports with a multicast MAC address, so the traffic will be flooded out all ports.  The flooding of the multicast traffic may cause unintended network performance issues.  To resolve these issues, you can configure the switch with static mappings of the multicast MAC and the ports that the NLB nodes are connected to.
