4. Protecting or Registering Server Names using Static Mappings

It is possible to enter NetBIOS name to IP address mappings manually into the WINS database and these entries are known as static mappings, and can be used to protect the names of critical servers. Microsoft do not generally advocate the use of static mappings except for servers that cannot register their own NetBIOS names into the WINS database and servers named in accordance with the naming standards should not need be entered as static mappings. However, if you have older servers that are not named in accordance with the naming standards, these can be entered into the WINS database as static mappings to protect their names.

In addition, if you operate your own WINS servers, but have external workstations that use the central WINS servers that need to be able to locate your servers, these server names can also be entered as static mappings into the central WINS databases. Doing so should allow external workstations using the central WINS servers to locate your servers without needing entries in their LMHOSTS files.

Static mappings can be made for server names, domain names, and Samba server NetBIOS names; be aware however that NT and 2000 workstations that are members of a domain really need to use the WINS servers that the domain controller uses, since they need an entry that is only registered by the primary domain controller and cannot be entered using a static mapping. This problem does not affect workstations accessing shares on the domain controller; it is only a problem for workstations that are actually members of the domain.

Please e-mail any static mappings required to winsmaster. You can include details of domain names as well as servers and you need to include the following information.

  • Whether the entry is unique (for a server name), multihomed (for a server with more than one IP address) or a domain.
  • For a unique or multihomed entry, give the IP address(es) and NetBIOS (or computer) name of the server. Note that this is not the same as its DNS name.
  • For a domain entry, give the IP address of the primary domain controller (NT) or first domain controller (2000) and the domain name.
