Project: Network Infrastructure Client: The British American International
	Solution Summary 3H Technology (3H) was tasked to implement a network infrastructure for British American International (BAI). 3H designed and deployed an advanced and secure network architecture capable of growth in support of BAI's international development center. The network configuration was automated and configured to provide ease of maintenance and support. BAI went many months with no designated IT personnel upon completion of the project. BAI Washington office was praised by the senior IT management staff for its network infrastructure.

CHALLENGE
3H Technology (3H) was tasked to design and deploy a Windows network environment to support BAI's web development, e-mail infrastructure, and the following supporting functions:

• Set a user account management solution to support both internal and international users.
  
• Implement a network address translation (NAT) architecture to support a secure robust internal IP address scope with minimal public IP addresses.
  
• Enable DHCP to manage a limited IP address scope while providing internet connection for remote visitors.
  
• Deploy DNS and WINS in support of NetBios names resolution.
  
• Provide a dynamic backup solution of critical systems and databases.
  
• Configure an advanced anti-virus solution.

• User account policies were configured to implement the latest security procedures. Directory access was restricted to user groups that in turn passed access to accounts. This solution provides a decentralized security policy outside of any one account and provides the greatest level of flexibility and accountability.
  
• A 128-bit security upgrade was applied to all the operating systems to provide the highest level of security. The 128-bit upgrade was prohibited outside the United States.
  
• A Windows 2000 NAT solution was deployed to provide BAI with virtually unlimited IP addresses with only a few public IP addresses. This solution enables internet traffic to be routed to the appropriate sub-network, depending on the IP packets. The NAT architecture restricted both port and protocol and was configurable to restrict or favor certain IP scopes and addresses.
  
• A DHCP scope was configured to provide BAI with both manageability and accountability of their IP address scope. Coupled with NAT, BAI was able to maintain an accurate and reliable IP address scope for more than 100 IP addresses.
  
• 3H resolved previous DNS record failures. Microsoft WINS service was installed on the back-end sub-network to manage NetBios name resolution while DNS was used to manage Internet name resolution. 3H configured and managed a separate DNS server within the NAT zone to minimize the effect of internal IP changes on development servers.
  


• Veritas Backup Exec was deployed to enable BAI to safeguard critical data. 3H continued to support BAI in managing effective deployment of Veritas to ensure all critical data was in the backup scheme. 3H developed maintenance plans within SQL that provided consistency checks and data transfer checks to ensure the viability of each database.
  
• Norton Anti-virus software was installed on all servers, workstations, and laptops to provide BAI with a reliable protective shield from software viruses. 3H configured Norton with dynamic updates and software pushes to ensure the latest anti-virus software installation.
