Abstract

VM PWSCS provides a communications network consisting of hundreds, even thousands, of workstations located throughout an enterprise. Installing a service update currently requires that each workstation user be notified when a service update is available. The workstation user must then manually run a program to apply the service on his workstation. This procedure makes it very likely that all of the workstations will never be at the same service level, making problem determination that much more difficult.

VM PWSCS Automated Software Service Distribution for Multiple Environments

      VM PWSCS provides a communications network consisting of
hundreds, even thousands, of workstations located throughout an
enterprise.  Installing a service update currently requires that each
workstation user be notified when a service update is available.  The
workstation user must then manually run a program to apply the
service on his workstation.  This procedure makes it very likely that
all of the workstations will never be at the same service level,
making problem determination that much more difficult.

      A VM PWSCS network consists of one or more domain controllers
and zero or more user workstations.  A domain controller is
responsible for managing the network, routing conversations,
authenticating users, and authorizing programs.  Domain controllers
are located in physically-secure areas and are not normally used by
end users.

      A user workstation is located in an office environment and is
used by the end user.  It is not physically-secure and is trusted
only after being authenticated by a domain controller.

      VM PWSCS will automatically track the service level installed
on each machine in the network.  This tracking is performed by the
domain controllers in the network.  When a new service level is
available, the network administrator needs only to install it on a
single domain controller.  This domain controller will then send the
new service level to all of the other domain controllers in the
network.

      Each time a user workstation is turned on, it identifies itself
to the network and attaches to one of the domain controllers.  As a
part of the workstation signon, the workstation tells the domain
control what service level is installed on the workstation.  If a new
service level is available, the domain controller will signal the
user workstation that a service update is available.  The user
workstation will retrieve the service update without any user
intervention.  The new service level will replace the current service
level on the user workstation and will be activated the next time the
workstation is turned on.  In addition, if t...
