Collection: Exchange Server 2003 (2)

1.    TELL ME WHY WE R USEING EXCHANGE SERVER?

This is a mail server. We can use this Server to send mails in Intranet as well as outside.

2.    What is a smart host?

A smart host is a common term for a server that accepts outbound mail and passes it on to the recipient.

DNS-

This is the standard for sending mail. When Exchange needs to send mail to another domain it will look for the MX records of that domain and will attempt to contact the mail server directly.

Smart host-

In this case Exchange takes your outgoing mail and sends it to another mail server (which is called a “smart host”, hence the name). The smart host will deliver your mail to the other mail servers on your behalf. This is exactly what you do when you use Outlook Express to send mail using your ISP SMTP servers.

3.     An Exchange server is having bandwidth issues, explain how you would look at fixing the issue?

4.    What are the different Exchange 2003 versions?          

Standard Exchange version, Enterprise Exchange version and Small Business Server.

5.     What are the main differences between Exchange 5.5 and Exchange 2000/2003?

The primary differences are.
-Exchange 2000 does not have its own directory or directory service; it uses Active Directory instead.
-Exchange 2000 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 servers.
-Exchange 2000 supports Active/Active clustering and was recently certified for Windows 2000 Datacenter.
-Exchange 2000 scales much higher.
-It boasts conferencing services and instant messaging.

6.    What are the major network infrastructures for installing Exchange 2003?

Hardware Requirements
There are several factors that affect the hardware requirements for Exchange Server 2003: the number of users that will be accessing the server; the size and number of messages transferred on a daily basis (not to mention during peak usage periods); availability requirements; and so on. These factors will have a significant influence on the type of hardware you use for your deployment.

Recursive vs Iterative Query.

With a recursive name query , the DNS client requires that the DNS server respond to the client with either the requested resource record or an error message stating that the record or domain name does not exist. The DNS server cannot just refer the DNS client to a different DNS server.Thus, if a DNS server does not have the requested information when it receives a recursive query, it queries other servers until it gets the information, or until the name query fails.

Recursive name queries are generally made by a DNS client to a DNS server, or by a DNS server that is configured to pass unresolved name queries to another DNS server, in the case of a DNS server configured to use a forwarder.

An iterative name query is one in which a DNS client allows the DNS server to return the best answer it can give based on its cache or zone data. If the queried DNS server does not have an exact match for the queried name, the best possible information it can return is a referral (that is, a pointer to a DNS server authoritative for a lower level of the domain namespace). The DNS client can then query the DNS server for which it obtained a referral. It continues this process until it locates a DNS server that is authoritative for the queried name, or until an error or time-out condition is met.This process is sometimes referred to as "walking the tree," and this type of query is typically initiated by a DNS server that attempts to resolve a recursive name query for a DNS client.

Difference betweenw SUS and WSUS

SUS did a great job of keeping Windows up to date, but WUS will be able to 

update other products such as Microsoft Office, Exchange Server and ISA Server.

Eventually, WUS will be able to keep all current Microsoft server products

up to date.

Comparison of Windows Server 2003 Editions

Standard Edition:  4-GB RAM Maximum

Enterprise Edition:  32-GB RAM Maximum, 64-bit Support for Intel Itanium-based, Hot Add Memory

Datacenter Edition:  64-GB RAM Maximum, 64-bit Support for Intel Itanium-based, Hot Add Memory

Web Edition:  2-GB RAM Maximum

In Active Directory a single server always holds at least three directory partitions:

• The schema
• The configuration (replication topology and related metadata)
• One or more per-domain directory partitions (subtrees containing domain-specific objects in the directory)

The KCC and Replication Topology 

The Knowledge Consistency Checker (KCC) uses site link configuration information to enable and optimize replication traffic by generating a least-cost replication topology. Within a site, for each directory partition, the KCC builds a ring topology that tries to set a maximum number of hops (3) between any two domain controllers. Between sites, the KCC creates a spanning tree of all intersite connections. Therefore, adding sites and domains increases the processing that is required by the KCC.

Difference between Windows Server 2000 and 2003

1) When installing terminal services for win2000 u r prompted to select application server functions 

or administrative functions sets can be installed sequently on one server but it performs only one 

function at one time.But in 2003 still distinguishes between application and administrative services 

but installation and management are now consolidated.

2) In Win 2000 server we can apply 620 group policies but in 2003 we can apply nearly 720 so 

Win2003 server is more secure than win 2000 server.

3) In 2000 we cannot rename domain whereas in 2003 we can rename Domain.

4) In 2000 it supports of 8 processors and 64 GB RAM (In 2000 Advance Server) whereas in 2003 

supports up to 64 processors and max of 512GB RAM.

5) 2000 Supports IIS 5.0 and 2003 Supports IIS6.0 

6) 2000 doesn’t support Dot net whereas 2003 Supports Microsoft .NET 2.0 

7) 2000 has Server and Advance Server editions whereas 2003 has Standard, Enterprise, 

  Datacenter and Web server Editions. 

8) 2000 doesn’t have any 64 bit server operating system whereas 2003 has 64 bit server operating 

systems (Windows Server 2003 X64 Std and Enterprise Edition)
