GIVE ME SOME DIFFERENCES BETWEEN WINS AND DNS? PLZ

Do you know NetBIOS? This is an old name resolution method which relies on broadcast traffic. Therefore it is limited to 1 subnet and causes a large amount of traffic on larger subnets. This implies a limit in the amount of systems you can connect. Later, a central server was designed to work around these limitations. So a WINS server resolves NetBIOS names (like HOSTNAME) to an IP adress. How this works is explained on http://support.microsoft.com/kb/119493 DNS, a far more modern approach, uses a central server from the beginning and has the possibility to make a hierachical structure, domains. DNS therefore is well suited to support large environments (like the internet). DNS resolves fully qualified domain names (FQND) like hostname.subdomain.domain.tld to an IP. How this works is explained on http://technet.microsoft.com/en-us/library/cc958812.aspx WINS was a very important network infrastructure service in the past, but is becoming depreciated.

Hello muppuri, WINS and DNS are both name resolution services for TCP/IP networks. While WINS resolves names in the NetBIOS namespace, DNS resolves names in the DNS domain namespace. WINS primarily supports clients that run older versions of Windows and applications that use NetBIOS. Windows 2000, Windows XP, and Windows Server 2003 use DNS names in addition to NetBIOS names. Environments that include some computers that use NetBIOS names and other computers that use domain names must include both WINS servers and DNS servers.
