An Overview of Link Local Multicast Name Resolution
When a user on a corporate network needs to access some resource off of another computer, the user usually specifies the remote system’s NetBIOS name when establishing the connection. This technique works well on corporate networks because the Active Directory mandates the existence of a DNS server. This means that users can attach to a remote system by using its NetBIOS name and Windows will query the DNS server in order to determine the IP addresses associated with the host record matching the computer’s name. That’s great for corporate networks, but name resolution has always been a problem for ad-hoc networks at home networks. In most cases, it is either impossible or impractical to add a DNS server to a home network or to an ad-hoc network. This makes name resolution impossible. Windows Vista in Longhorn Server will change this with the new technology called link local multicast name resolution.(continue at source)
