Solution Profile

The United States Army - Pacific (USARPAC) migration consolidates the NT Domains and Exchange Sites down to one Active Directory Domain and 5 Exchange 2003 Sites. This goal has the effect of not only consolidating hardware and services in each region, but it also enables the centralization of the management of Enterprise Operations through the implementation of Windows Server 2003 Active Directory and Exchange Server 2003. The architecture chosen for this project supports the Active Directory and Exchange 2003 infrastructure and ensures redundancy of core networking services, the high availability of the messaging systems, and meets the security requirements of NETCOM.

The Problem

The scope of USARPAC's migration encompassed four disparate regional areas which collectively hosted over 30 NT Domains and 8 Exchange 5.5 Sites that serviced more than 19,000 User Accounts and over 18,000 mailboxes respectively.

The Solution

CTA Engineering deployed the following architecture to achieve USARPAC's goals: four-node and two-node Exchange 2003 mailbox clusters; load balanced SMTP bridgeheads; redundant domain controllers and DNS servers; NTECOM security templates and GPOs used in server builds and Active Directory deployment; and Dell SAN for the redundancy of messaging databases. They also added multiple layers of AntiVirus and SPAM protection from two vendors in order to ensure the maximum coverage of protection.

The end state of the USARPAC migration is a centralized and consolidated architecture running state of the art operating systems, applications, and hardware in support of the USARPAC enterprise.

Solution Benefits

  • USARPAC is now able to centrally manage all workstations

  • Ease of security configurations implementation across the entire enterprise

  • CTA Engineering centralized the management of the entire USARPAC messaging infrastructure

  • Ability to monitor all critical services of the architecture

  • Centrally manage the messaging AntiVirus and SPAM infrastructure for the more than 18,000 mailboxes
