Maintaining highly available systems requires not only good choices in technology, but careful attention to design and operational practices. For more information about practices that enhance availability, see the following:

• By following best practices for the technologies you use, you can prevent problems before they start, increasing system availability. For information about best practices for specific technologies, see the list in Best practices: pointers to recommendations and tips.
  
  
• By following best practices for security, you protect against attacks that could decrease system availability. For more information, see Best practices for security.
  
  
• By understanding the deployment and management practices described in the Windows Resource Kits, you can design, test, and operate systems in ways that maximize availability. For more information, see the following:
