Exchange 2000 Hosting: The ASP Model, Part 2

Exchange Server hosted in an application service provider (ASP) environment is similar to a corporate Exchange deployment. Smart IT departments can think of themselves as ASPs, with their own organization as their customer. This article is the second in a series about the Exchange 2000 Server lessons you can learn from ASPs.

In "Exchange 2000 Hosting: The ASP Model, Part 1," November 2001, I described the front-end/back-end architecture that ASPs use for Exchange and told you that ASPs typically establish one Active Directory (AD) forest with a separate organizational unit (OU) for each company they host. Likewise, you might set up one AD forest, with a separate OU for each of your corporate divisions. I also showed you how to define a user principal name (UPN) suffix for a division—Division A—and associate it with the logon names of the users in that division. (For an explanation of how to create a UPN suffix as an OU property, see the sidebar "Creating a UPN Suffix as an OU Property," page 12.) . . .
