Question { 16255 }

What’s the main differences between exchange 5.5 and
Exchange 2000/2003

Answer

The primary differences are...
-Exchange 2000/2003 does not have its own directory or
directory service; it uses Active Directory instead.
-Exchange 2000/2003 uses native components of Windows 2000
(namely, IIS and its SMTP, NNTP, W3SVC and other
components, Kerberos and others) for many core functions.
-SMTP is now a full peer to RPC, and is it the default
transport protocol between Exchange 2000/2003 servers.
-Exchange 2000/2003 supports Active/Active clustering and
was recently certified for Windows 2000 Datacenter/2003.
-Exchange 2000/2003 scales much higher.
-It boasts conferencing services and instant messaging.

Question { 13562 }

What is the Send as permission?

Answer

Active Directory Users and Computers or the Exchange
Management Shell to grant the Send As permission for a
mailbox.
Use the Send As permission in Microsoft Exchange Server to
configure a mailbox so that users other than the mailbox
owner can use that mailbox to send messages.
After this permission is granted, any messages that are
sent from the mailbox will appear as if they were sent by
the mailbox owner.

Question { 31715 }

What are exchange Recipient types ? Name 5

Answer

The people and resources that send and receive messages are
the core of any messaging and collaboration system. In an
Exchange Server organization, these people and resources
are referred to as recipients.

A recipient is any mail-enabled object in the Active
Directory directory service to which Exchange can deliver
or route messages. This topic discusses the recipient types
that are supported in Microsoft Exchange Server 2007.

User mailbox

A mailbox that is assigned to an individual user in your
Exchange organization. It typically contains messages,
calendar items, contacts, tasks, documents, and other
important business data.

Linked mailbox

A mailbox that is assigned to an individual user in
a separate, trusted forest.

Shared mailbox

A mailbox that is not primarily associated with a single
user and is generally configured to allow logon access for
multiple users.

Legacy mailbox

A mailbox that resides on a server running Exchange Server
2003 or Exchange 2000 Server.

Room mailbox

A resource mailbox that is assigned to a meeting location,
such as a conference room, auditorium, or training room.
Room mailboxes can be included as resources in meeting
requests, providing a simple and efficient way of
organizing meetings for your users.

Question { 10011 }

What are Query Based Distribution groups?

Answer

A query-based distribution group provides the same
functionality as a standard distribution group.

However, instead of specifying static user memberships, you
can use an LDAP query (for example, "All full-time
employees in my company") to dynamically build membership
in a query-based distribution group.

This reduces administrative costs because of the dynamic
nature of the distribution group. However, query-based
distribution groups have a higher performance cost for
queries whose outcome produces many results.

This cost is in terms of server resources, such as high CPU
usage and increased memory usage. This increased usage
occurs because every time an e-mail message is sent to a
query-based distribution group, an LDAP query is executed
against Active Directory to determine its membership.

Question { 9932 }

What are virtual servers? When would you use more than one?

Answer

Exchange Virtual Server is a clustered Exchange
installation. When Exchange is installed on a Windows
Server 2003 cluster,
it is configured as an Exchange Virtual Server that can be
passed between cluster nodes transparently to Exchange
clients.

1. SMTP Virtual Server, 2. HTTP Virtual Server, 3.POP3
Virtual Server, 4. IMAP4 Virtual Server and so on

Question { 8139 }

Name some of the SMTP Virtual server configuration options.

Answer

The following table lists important configuration
information that Exchange Server 2003 stores for SMTP
virtual servers in Active Directory.

Important Active Directory attributes for SMTP virtual
servers

msExchServerBindings -Specifies the Internet Protocol
(IP) port binding for Secure Sockets Layer (SSL)
connections.

msExchAuthenticationFlags -Indicates which type of
authentication this SMTP virtual server accepts.

msExchMaxIncomingConnections -Specifies the maximum
number of inbound connections allowed for this SMTP virtual
server.

msExchLogType -Specifies the log formats that this SMTP
virtual server uses for protocol logging.

msExchAccessSSLFlags -Identifies the type of encrypted
channel that this SMTP virtual server supports.

Question { 11796 }

What is a Mail Relay? Name a few known mail relay software
or hardware options.

Answer

Often referred to as an e-mail server, a device and/or
program that routes an e-mail to the correct destination.
Mail relays are typically used within local networks to
transmit e-mails among local users.

(For example, all of the student and faculty e-mail of a
college campus.) Mail relays are particularly useful in e-
mail aliasing where multiple e-mail addresses are used but
the mail relay forwards all messages to the specified e-
mail addresses to one single address.

A mail relay is different than an open relay, where an e-
mail server processes a mail message that that neither
originates or ends with a user that is within the server’s
local domain (i.e., local IP range).

Mail relay Softwares:
1.NoticeWare Email Server 4.3
2. Flash Mailer 20.

Question { 12991 }

What is a smart host? Where would you configure it?

Answer

A smart host is a type of mail relay server which allows an
SMTP server to route e-mail to an intermediate mail server
rather than directly to the recipient’s server.

Often this smart host requires authentication from the
sender to verify that the sender has privileges to have
mail forwarded through the smart host.

This is an important distinction from an open relay that
will forward mail from the sender without authentication.
Common authentication techniques include SMTP-AUTH and POP
before SMTP.

1.Use for backup mail (secondary MX) services

When configured to be a backup mail server (not the primary
MX record) a smart host configuration will accept mail on
behalf of the primary mail server if it were to go offline.
When the primary mail server comes back online, mail is
subsequently delivered via the smart host.

2.Use in spam control efforts

Some ISPs, in an effort to reduce e-mail spam originating
at their customer’s IP addresses, will not allow their
customers to communicate directly with the recipient’s mail
server via the default SMTP port number 25. In this case
the customer has no choice but to use the smart host
provided by the ISP.
A growing number of systems also verify the sending system
against known lists of cable modem and DSL networks and
will not accept SMTP connections from these systems to
reduce the amount of incoming spam. Field tests have shown
this can have a sizable impact on the number of spam
messages one receives and it is expected to become more and
more common
3.Use in centralizing email services
When a host runs its own local mail server, a smart host is
often used to transmit all mail to other systems through a
central mail server. This is used to ease the management of
a single mail server with aliases, security, and Internet
access rather than maintaining numerous local mail servers.

Question { Cognizant, 13529 }

What are Routing Groups? When would you the them?

Answer

A routing group is a logical collection of servers used to
control mail flow and public folder referrals. In a routing
group, all servers communicate and transfer messages
directly to one another.

In a routing group, all servers communicate and transfer
messages directly to one another, as follows:

1. A user in your Exchange organization uses a mail
client to send mail to another user.

2. Using SMTP, the sender's client submits this mail
to the SMTP virtual server on the Exchange server on which
the client's mailbox resides.

3. The Exchange server looks up the recipient of the
mail message to determine which server the recipient's
mailbox resides on.

4. One of two things occurs:
• If the recipient's mailbox is on the same Exchange
server, Exchange delivers the message to the recipient's
mailbox.

• If the recipient's mailbox is on another Exchange
server, the first Exchange server sends the message to the
recipient's home mailbox server, and it is the recipient's
home mailbox server that delivers the message to the
recipient's mailbox.

Question { ABC, 14327 }

What are the types of connectors you can use in exchange?

Answer

• Routing group connector

The routing group connector is the recommended connector
for connecting routing groups that are in the same Exchange
organization. This connector uses SMTP to transfer messages
to other servers running Exchange Server 2003. The routing
group connector can only be used to connect routing groups.

• SMTP connector

The SMTP connector establishes a messaging route between
two routing groups or between a routing group and a non-
Exchange SMTP host. Although the routing group connector
and the SMTP connector use SMTP as the transport protocol,
the SMTP connector provides additional functionality in
that it can be used to connect an Exchange organization
with any SMTP server.

• X.400 connector

The X.400 connector establishes an X.400 messaging route
between two routing groups or between a routing group and
an X.400 system. Like the routing group connector and the
SMTP connector, an X.400 connector can be used to link
Exchange routing groups. Generally, X.400 connectors are
used only when connecting to other X.400 messaging systems.

Exchange Server 2003 supports the following optional
connectors that you can use to connect the organization to
non-Exchange messaging systems:
• Exchange Calendar Connector

Exchange Calendar Connector is used for exchanging
free/busy information between an Exchange organization and
a Lotus Notes or Novell GroupWise messaging system.

• Exchange Connector for Lotus Notes

• Exchange Connector for Novell GroupWise

Question { 9387 }

What is the link state table? Who would you view it?

Answer

Every Exchange server maintains its own routing table,
called the link state table, dynamically in memory, based
on Active Directory and link state information,

as follows:
• Routing-related Active Directory information This
information is stored in attributes of the organization
object, routing group objects, connector objects, and
server objects. These objects reside in the configuration
directory partition and define the routing topology of the
entire Exchange organization.

• Link state information This information specifies
whether each connector in the routing topology is available
(up) or unavailable (down). Link state information is
dynamic and might change when a connector experiences
transfer problems or when transfer issues are resolved.

view Link state table
you can use to view Link state table in Exchange Server
2000/2003 WinRoute tool (Winroute.exe)

Question { 7444 }

What is the Rouging Group master? Who holds that role?

Answer

When you create a routing group, the first server in that
routing group is assigned the role of routing group master.

The routing group master keeps track of the link state
information and propagates it to the other servers in the
routing group, and other servers communicate back any
changes in link state.

For example, if a member server tries to contact another
server over a connector, and this link is unavailable, the
member server immediately notifies the routing group
master.
Likewise, when a non-master receives new link state
information, it immediately transfers the link state
information to the master, so that other servers can
receive the information about the routing change

Question { 12413 }

What is DS2MB

Answer

Metabase update service, also referred to as the directory
service/metabase synchronization process, or DS2MB (because
this process is implemented in DS2MB.dll) is a component in
Exchange Server 2003 that is used to synchronize several
Exchange configuration settings in Active Directory with
counterpart settings in the IIS metabase. The function of
DS2MB is to replicate configuration information from Active
Directory to the local IIS metabase.

Question { 5636 }

What is forms Based Authentication

Answer

Forms-based Authentication

Exchange 2003 has a snazzy new feature called Forms-based
Authentication, which I'll refer to as FBA. FBA is the new
logon security feature for Outlook Web Access (OWA) which
is disabled by default in Exchange 2003.

There are several security benefits to running FBA:

1. If the session is inactive for a period of time, the
session will expire. The only way to gain access again is
to re-authenticate. More on this later.

2. Users can no longer click the Remember my password check
box in Internet Explorer.

3. Like the session inactivity setting, if you log out, you
really log out. The only way to gain access again is to re-
authenticate. Previously in Exchange 2000, the user had to
complete the logout session by closing the browser window
