Select whether to use the same credentials or different credentials enter them as necessary and click OK. Summary Administration of an ISA server is relatively straightforward assuming the proper controls have been put into place to restrict console access to the proper individuals. Through the use of an auditable controlled access mechanism such as that which role-based access controls can give access to administer an ISA Server 2006 environment can be easily controlled and monitored. Best Practices Use the concept of role-based access control to delegate administrative access to an ISA server and to other network resources. Use the Remote Desktop Protocol RDP to administer an ISA server when possible rather than using the ISA Administrator MMC Console remotely. Use the lockdown mode functionality of an ISA server to protect it from attacks and denial of service attempts. Create groups to correspond with each of the ISA administrative roles such as ISA Full Administrator ISA Basic Monitoring and ISA Extended Monitoring. CHAPTER 17 Maintaining ISA Server 2006 By and large ISA Server 2006 does a great job in keeping itself in working order with a fairly low amount of maintenance required. As with any complex system however getting the most out of an ISA Server implementation requires that certain best-practice procedures be performed on a regular basis. These procedures can range from simple daily tasks such as checking the ISA admin console for alerts and updates to complex issues such as performing operating system ISA and hardware upgrades. This chapter focuses on the best-practice maintenance procedures that should be performed to keep ISA Server 2006 in top shape. Guides and checklists for ISA maintenance are included and step-by-step maintenance procedures are outlined. IN THIS CHAPTER Understanding the Importance of a Maintenance Plan for ISA Updating ISA s Operating System Performing Daily .
