Abstract The expansion of the organization has allowed the IT department to design a network that will allow each office to share the same Internet Domain Name while still being located in separate offices. The organization currently own 25 servers and they expect to have to purchase up to thirty more to accommodate the new branch office. The design will allow for providing service to 5000 users with the thought of future growth being applied to the new network design. It has been suggested that

1. What is the purpose if the Global Names Zone in Windows Server 2008 DNS servers? Global Names Zone is intended to aid the retirement of Windows Internet Name Service. It is not intended to support the single-label name resolution of records that are dynamically registered in WINS. Support for these dynamically registered records is not scalable, especially for larger costumers with multiple domains or forests. After enabling the Global Names Zone, the administrator must manually create, add,

often caused by having the wrong DNS server configured on the client, sending DNS requests that the server does not have in its database, or packet loss on the network. DNS is a UDP-based protocol, so packets that are lost will not be retransmitted, causing DNS to fail Resolution: Check the client configuration to see which DNS server it is setup to use. If this is the wrong server, adjust this setting in the client or in the DHCP server which provided it. Test the DNS server from the client connection

Knowing what is best for the organization should be based on their current size and equipment needs. A small office with only 2 computers would not require new equipment to be installed. In this size office I would recommend statically assigning the IP addresses to the two computers and using the DNS that
