Restarting the SQL Server service causes all current DoS connections to be disconnected. A paused service might give the impression that the server has crashed, causing an automated DoS attack designed simply to bring down the server to finish. If the DoS attack is targeted at Windows rather than at SQL Server, attempting a reboot of the server might cause a DoS attack to stop for similar reasons.

Most Exchange administrators do not earn the big dollars because they know how to create a user mailbox or an address list. Great Exchange administrators earn their wage by being cool, calm, and confident during a crisis. For an Exchange administrator, there is no bigger crisis that you will have to resolve than recovering a mission-critical Exchange Server when some catastrophic event occurs. In the first lesson in this chapter, you will learn the procedures that allow you to recover each of the separate Exchange Server 2007 roles. The second part of this chapter covers how you can apply different high availability strategies to each Exchange Server 2007 roles. In terms of high availability, there is no one-size-fits-all solution. High availability techniques that are suitable for one Exchange Server 2007 role are completely inappropriate for other roles. In the second lesson of this chapter, you will learn which high availability strategy to apply to a particular server role to best meet the needs of your organization.

Two types of computer naming systems exist in Windows Server 2003 networks: DNS and NetBIOS To resolve computer names, the DNS Client service in Win dows Server 2003 always attempts DNS name resolution before NetBIOS name resolution DNS names and the DNS protocol are required for Active Directory domains and for compatibility with the Internet or intranets DNS host names cannot exceed 63 bytes The DNS namespace is hierarchical and is based on a unique root that can have any number of subdomains An FQDN is a name of a DNS host in this namespace that indicates the host s location relative to the root of the DNS domain tree An example of an FQDN is host1subdomainmicrosoftcom A DNS zone is a contiguous portion of a namespace for which a server is author itative.
