System attendant

One of the core Exchange 2000 services that performs miscellaneous functions (usually related to directory information) such as generation of address lists, offline Address Books, and directory lookup facilities.

T.120

A standards-based protocol used with Exchange Data Conferencing. Clients such as Microsoft NetMeeting are T.120 compatible.

User

In Active Directory, this is a security principal (a user who can log on to the domain). A user may have an e-mail address and/or an Exchange mailbox, making the object mail- enabled and/or mailbox-enabled, respectively.

User Principal Name – UPN

A multi-valued attribute of each user object that the system administrator can set. A UPN allows the underlying domain structure and complexity to be hidden from users; for example, although 50 domains may exist within a forest, users would seamlessly log on as if they were in the same domain. For consistency purposes, system administrators can make the UPN and users’ SMTP address the same.

A user can log on to Active Directory through a number of different methods:

◆By specifying the user name and domain name

◆By using the convention of username@domain-namein the user box

◆By using his or her UPN, such as e-mailalias@microsoft.com

Virtual root

A shortcut pointer to a physical storage location. Virtual roots are normally defined to allow users and applications to connect with a short ”friendly” path instead of navigating a complex hierarchy.

Internet Information Server (IIS) uses the concept of virtual roots to expose resources provided by a web server.

Virtual server

An instance of any service type normally implemented in Internet Information Server (IIS). For example, a virtual server can be an instance of:

◆FTP

◆IMAP

◆Instant Messaging (RVP)

◆HTTP

◆NNTP

◆POP

◆SMTP
