are maintained for a period sufficient to propagate the information to all WINS
servers, after which the extinct name is removed from the WINS database. If a
computer has released its name through an orderly shutdown, WINS knows that the
name is available and the client can immediately re-obtain the name when it reenters
the network.
If a computer is not shut down in an orderly fashion, its name reservation remains
active in the WINS database. When the computer attempts to reregister the name,
the WINS server challenges the registration attempt. If the computer has changed IP
addresses, the challenge fails and the client is permitted to reregister the name with
a new address. If no other computer is actively using the name, the client is also
permitted to reregister with the name.
All names in the WINS database bear a timestamp that indicates when the
reservation will expire. If a client fails to reregister the name when the reservation
expires, the name is released.
To support true network connectivity to the Mission Control Center (MCC) after
OCA Router arrives onboard, the following static WINS addresses have been added
to the File Server (see Proprietary Table E-4 STATIC WINS ADDRESSES).
3.3 Operational Issues
3.3.1 Web Browser Security Policy
Software and web page developers should be made aware that the Microsoft
Internet Explorer (MSIE) web browser cannot be updated via the automatic
download feature that ordinarily searches the Internet for new controls and plug-
ins. SSC Client laptops are equipped with MSIE for viewing and interacting with
HTML files located on the OPS LAN. MSIE has a built-in feature for acquiring
software modules (JAVA plug-ins, ActiveX controls, etc.) from the Internet for the
purpose of adding features and expanding functionality. However, to ensure the
integrity of SSC software, this feature has been disabled. Developers should submit
a S-POCCB Change Request (CR) to request the modifications needed by MSIE to
support developers’ applications.
