Limitations on File Server memory and the requirement of crew intervention with
PC Card handling makes automatically backup scheduling impracticable at this
time. (Manual startup)
3.2.12 Windows Internet Naming Service (WINS)
Because of the flexible and dynamic nature of the OPS LAN (moving OPS LAN
devices between different ISS modules, switching devices between coax and RF
connectivity, exchanging PCMCIA components, etc.), active communication
between clients and the server is necessary to maintain fault-tolerant performance.
Microsoft’s Windows Internet Name Service (WINS), which provides NetBIOS name
to IP address mapping in response to queries from clients, fulfills this need. The OPS
LAN file server maintains the WINS database which tracks the current status of
client availability. Each client device is configured to communicate its presence to
the OPS LAN file server.
When a computer attempts to register a NetBIOS name with the WINS database on
the file server, it is permitted to do so only if the name is not currently reserved in
the WINS database. When a WINS client is shut down in an orderly manner, it
releases its name reservation in the WINS database and the name is marked as
released. After a certain time, a released name is marked as extinct. Extinct names
