Chapter 7 AS/U in a Subnetted Domain

Advanced Server/9000 uses an IP broadcast based method to send datagrams to entire domains and to resolve NetBIOS names to IP addresses. These IP broadcasts are usually not routable across subnets. Thus, if you using Advanced Server/9000 in multi-subnet domain environments, you need a way to forward domain based datagrams (for example, netlogon requests) to clients and servers on different subnets. You also need a way to resolve the NetBIOS names to IP address of clients and servers on different subnets. Listed below are some approaches to solving this problem with AS/U.
