No they do not. The idea behind the GlobalNames zone in Windows Server 2008 is that no client configuration is needed. Just remember that you need to meet these requirements.
· DNS Servers must be Windows Server 2008.
· Global Names Zone must be enabled (DNSCMD /config /enableglobalnamessupport 1) on each DNS server.
· A forward lookup zone named GlobalNames must be set up on each DNS server that
· · · Is active directory integrated
· · · Does not support dynamic updates (recommended)
· You must provide a CNAME record mapping the client name to its FQDN.
When a client makes a single name request to a DNS server, DNS will check all its zones to try and match it to a FQDN. This will not work. After DNS has exhausted all its zones, it will look in the Globalnames zone. There, should it be present, it will locate a CNAME record for that single name. It will point to the FQDN record in the forward lookup zone. DNS will now return the IP address to the requesting node.
