Q.2 Where is the Directory Service database stored in Exchange 5.5?
Answer: Dir.edb
Q.3 Mention the types of Routing Group Connectors in Exchange 2000?
ANSWER:
A Routing Group is a collection of Exchange servers that communicate with each other directly over the same internal network or reliable connection.
When multiple Routing Groups must be created, each individual group must be connected using one of three available Exchange connection types:
<>· <>Routing Group Connector This connector is the default connector type. It can be used to connect a single or multiple Exchange bridgehead server for load balancing of message traffic.
<>· <>SMTP Connector The SMTP connector uses the Simple Mail Transport Protocol to connect and communicate with remote Routing Groups, non-Exchange mail systems, and the Internet mail host.
<>· <>X.400 Mail Connector Limited to a single local and remote host, the X.400 connector is primarily designed for communications between Exchange Server 2003 and X.400 mail systems.
Mixed Mode
When Exchange Server 2003 is in a mixed environment, Routing Groups can consist of only servers that had been installed directly into the Administrative Group where the Routing Group resides. Additional servers from other Administrative Groups cannot be added to the Routing Group.
Native Mode
After the functional level has been raised to Native Mode, Exchange servers can be managed and moved between Routing Groups.
Also, Routing Groups in a single Administrative Group can contain servers from other Administrative Groups.

Q.7 How to restore Group policies?
Answer:-
dcgpofix
Backup and Restore
From GPMC, it is easy to perform backup and restore operations. Backup and restore operation options are context-sensitive, depending on where you are within the Group Policy Objects node.
- Click on the Group Policy Objects note to display all GPOs in the domain.
- Select the target GPO(s) for backup. For multiple GPOs:
- For a range of GPOs, select the first GPO, press SHIFT and click on the last GPO.
- For multiple non-contiguous GPOs, select the first GPO, press CTRL and click on other GPOs.
- Right-click and select Backup...
- On the next window, speficy the backup directory and description and click Back Up.
- Click OK when done.
Backup All GPOs
This operation is normally performed by domain administrators.
- Select the Group Policy Object node.
- Right-click and select Backup All...
- Specify the backup directory and description and click Back Up.
- Click OK when done.
Restore GPO
- Within the Group Policy Object node, select the target GPO.
- Right-click and select Restore from Backup... This will launch the Restore Group Policy Object Wizard.
- Click Next.
- Specify the correct backup folder location.
- If multiple backups have been done, choose the correct backup version. The Source GPO window displays the GPO name, backup timestamp and description. You can also check the settings on the source GPO by clicking on the View Settings... button.
- Click Next.
- Click Finish when ready to restore.
- Click OK when done. You have now restored the GPO.

Q.8 what is the function of NNTP service in Exchange 2000?
Answer:-While installing Exchange 2000, the system creates a default Network News Transfer Protocol (NNTP) virtual
server. You can use this virtual server to house a feed from other newsgroups
This Default NNTP virtual server can be used to create feeds to a Public Folder for storage (Internet Newsgroups).
For other storage media (either a file system or remote share), you must create a new virtual server.
NOTE:- Sir , Please Add
Network News Transfer Protocol
Because Network News Transfer Protocol (NNTP) is growing in popularity, it would be wise for us to take a brief look at the architecture of this protocol. We'll then discuss the more pragmatic aspects of administering NNTP on your network.
NNTP Architecture
NNTP specifies a way to distribute, query, retrieve, and post news articles on the Internet. A client wanting to retrieve a subset of articles from the database is called a subscriber. NNTP allows a subscriber to request a subset of articles rather than requiring the retrieval of all articles from the database. Before NNTP was developed, two methods of distributing news items were popular: Internet mailing lists and the Usenet news system.
An Internet mailing list, commonly known as a list server, distributes news by the use of distribution e-mail lists. A subscriber sends a message to the distribution list, and the message is e-mailed to all of the members of the list. But sending a separate copy of an e-mail to each subscriber can consume a large amount of disk space, bandwidth, and CPU resources. In addition, it can take from several minutes to several hours for the message to be fully distributed, depending on the size of the list and the physical resources available to propagate it. Maintaining the subscriber list also involves significant administrative effort, unless a third-party program is used to automate this function.
Storing and retrieving messages from a central location instead of sending an email to each subscriber can significantly reduce the use of these resources. The Usenet news system provides this alternative. In addition, Usenet allows a subscriber to select only those messages he or she wants to read and also provides indexing, cross-referencing, and message expiration.
NNTP is modeled on the Usenet news specifications in RFC 850, but it is designed to make fewer demands on the structure, content, and storage of the news articles. It runs as a background service on one host and can accept connections from other hosts on the LAN or over the Internet.
When a subscriber connects to an NNTP server, the subscriber issues the NEWSGROUPS command to determine whether any new newsgroups have been created on the server. If so, the server notifies the subscriber and gives the subscriber the opportunity to subscribe to the new newsgroups. After this, the subscriber is connected to the desired newsgroup and can use the NEWNEWS command to ask the server whether any new articles have been posted since the subscriber's last connection. The subscriber receives a list of new articles from the server and can request transmission of some or all of those articles. Finally, the subscriber can either reply to a news article or post a new article to the server by using the POST command.
NNTP uses TCP for its connections and SMTP-like commands and responses. The default TCP port for NNTP is 119. An NNTP command consists of a command word followed in some cases by a parameter, and commands are not case sensitive. Each line can contain only one command and may not exceed 512 characters, including spaces, punctuation, and the trailing CR–LF (carriage return/line feed) command. Commands cannot be continued on the next line.
Responses from the server can take the form of a text response or a status response. Text responses are displayed in the subscriber's client program, whereas status responses are interpreted by the client program before any display occurs.
Q.9.What is Recepient Update Service in Exchange 2000?
Answer:- Recipient Update Service (RUS) is a very important component in your Exchange installation, it is RUS that is
responsible for updating address lists and email addresses in your Active Directory
Default Exchange organization will have two RUS objects
(a)
system objects such as the MTA & System Attendant.
(b) Domain RUS :-responsible for the updating of the address information for recipient objects
in the domain that it is responsible for
Q.10 The function of the Default SMTP Virtual Server in Exchange 2000?
Answer:-SMTP virtual server plays a critical role in mail delivery.
SMTP virtual servers provide the Exchange mechanisms for managing SMTP.
the default SMTP virtual server sends messages within a routing group.
Additionally, if the server is a domain controller, Active Directory uses
this virtual server for SMTP directory replication . An SMTP virtual server is defined by a
unique combination of an IP address and port number.
The default SMTP virtual server uses all available IP addresses on the server and
uses port 25 for inbound connections.
A single physical server can host many virtual servers
