Methodology for Resolution of Ambiguous Distribution Network Names

      This article describes a methodology for allowing a Local Area
Network (LAN) Domain Controller to manage a list of known servers so
that requesting install applications can prevent installation of
duplicate server names when servers are powered off.

      Installing a new LAN server can create duplicate server names
when a same named server happens to be installed to a machine which
is powered off. The identically named server can be installed because
a LAN is not aware of machines which are powered off. If a server is
inactive, the server installation procedure will allow an
administrator to duplicate the server name. When the existing server
which was previously powered off tries to initialize during power up,
an error will occur because of a duplicate name. Only one of the
servers can be active at any time since they share the same name.
Upon recognition of this error condition, one of the servers must be
reinstalled with a different name.

      Creation of a Domain Controller service maintaining the list of
known network servers solves this problem. The Domain Controller
service creates and maintains a server name list with all server
names registered in that LAN. Server installation routines can call
the Domain Controller service when a new server is to be installed
and registered. The Domain Controller service will verify the new
server name against the known server name list. This...
