Step 2: Update All Servers with Security Patches
To help you ensure that your mobile messaging network is strong from end to end, take this opportunity to update all of your servers.
After you install Exchange Server 2003 SP2 on your front-end server, update the server software on your other Exchange servers and on any other server that Exchange communicates with, such as your global catalog servers and your domain controllers.
For more information about updating your software with the latest security patches, see the Exchange Server Security Center Web site.
