To enable DNS load balancing among a primary DNSserver and its secondary servers

Stub Zone

Name server (NS) records to identify authoritative

servers A record for name servers that are authoritative

One common use for a stub zone is to help quickly

Between two different namespaces

Additional DNS Server Roles

forward name resolution requests to a specificremote DNS server

A DNS server can function as a caching server

A caching server is used to provide fast queriesecause t e resu ts o eac query are store n

One limitation of using caching servers is that it takes

resolved names to IP addresses

Windows Internet Namin Service WINS

Used to register NetBIOS computer names and mapthem to IP addresses for any systems that use

WINS automatically registers network clients that

Builds a database that other network clients can queryin order to locate a computer

WINS consists of two main parts: the WINS serverand the WINS database

Im lementin Microsoft DHCP

Enables a Windows Server 2008 server with DHCPservices to detect the presence of a new workstation

Assign an IP address to that workstation

The DHCP server has a pre-assigned range of IPaddresses that it can give to a new client

Microsoft DHCP server can support the following:
