When Nomura were looking to design and integrate Windows NT Server and Workstation builds into the existing PC and Unix environment for the first time, CAT was enaged to provide strategic design and technical architecture input into this project. CAT personnel formed part of a team that was responsible for defining the Windows NT strategy, infrastructure, standard builds, network and domain structure for Nomura.

CAT's main responsibilities were to write the Terms of Reference and Technical Overview documentation as well as to produce a complete task list and plan the various stages of the project. CAT was also tasked with the formulation of the strategy for the Windows NT domain model. Once the design work was completed successfully, a Consultant from CAT was engaged to carry out the implementation of this domain model into the Nomura networking environment.

CAT personnel were also heavily involved in the design of all aspects of the new PC client, based on Windows NT 4.0. This involved deciding how best to present core applications to users, defining a default user profile, local and network security, writing logon scripts and building an automated installation process. All of this work was set against the requirement for the new PC client to integrate seamlessly with the existing UNIX data and applications servers using NFS and NIS.

CAT also assisted technical staff at Nomura with the integration of existing PC applications (there were at least 150) into the new Windows NT 4.0 environment and the preparation of automated installation routines using WinInstall.
