Understanding GlobalNames Zone in Windows Server 2008
Today, before the introduction of windows Server 2008, many Microsoft-based networks deploy WINS technology and servers in their environment. WINS is an alternative name resolution protocol to DNS. It is an older service that uses NetBIOS over TCP/IP (NetBT), mostly used in older operating systems such as Windows 95/98 and Windows NT 4.0. WINS and NetBT do not support IPv6 protocols and both are entering legacy mode for Windows Server 2008, and since Windows 2000 Server and beyond, most network services are no longer based upon NetBT name resolution, and use DNS names instead. That is why, in most cases, it is assumed that clients would want to retire their WINS infrastructure in favor of DNS name resolution.(continue at source)
