In repair mode, Eseutil f ixes individual tables but does not maintain the relationships between tables. You can use the Information Store Integrity Checker (Isinteg) to check and f ix links between tables if the repaired database is a mailbox or public folder database. Also in integrity mode Eseutil does not verify integrity at the application level. You can verify application-level logical integrity with Isinteg for mailbox and public folder databases. Isinteg is described later in this lesson.

In some cases, a DHCP server can return a DHCP Negative Acknowledgment (DHCP NACK) message to the client instead of the ACK in step 2. The NACK message is sent to a client to indicate that the IP address that the client has requested cannot be provided by the DHCP server. This situation can occur when a client requests an invalid or duplicate address for the network. If a client receives a negative acknowledgment, the lease renewal fails. In this case, the client begins a new lease initializa tion process.

Address lists are a method of organizing recipients. Address lists can be used to organize recipients on the basis of user account properties, such as department, company, or location. Clients are able to examine address lists to find recipients to which they wish to send messages. For example, a large organization has branches in many states. A separate address list has been created for each state. A client looking for the address details of a person she knows works in a particular state can just consult that state s address list rather than searching through all the addresses in the organization. The following default address lists are created during the setup of Exchange:

You can share an existing nonshared printer if your printing load increases. You can download additional print drivers so that clients running other versions of Windows can use the shared printer. You can stop sharing an existing shared printer. You can create a printer pool with multiple printers so that print jobs are automatically distributed to the first available printer. In this way, users do not have to search for an available printer. You can set priorities among printers so that critical documents always print before noncritical documents.
