Difference between MS outlook and Outlook express? Tell 5 differences.
Built on open Internet standards, Outlook Express is designed for use with any Internet standard system, for example, Simple Mail Transfer Protocol (SMTP), Post Office Protocol 3 (POP3), and Internet Mail Access Protocol (IMAP). It provides full support for today’s most important e-mail, news, and directory standards such as Lightweight Directory Access Protocol (LDAP), Multipurpose Internet Mail Extension Hypertext Markup Language (MHTML), Hypertext Markup Language (HTML), Secure/Multipurpose Internet Mail Extensions (S/MIME), and Network News Transfer Protocol (NNTP). Full support ensures that you can take advantage of new technologies as well as seamlessly send and receive e-mail.
New migration tools that automatically import your existing mail settings, address book entries, and e-mail messages from Eudora, Netscape, Microsoft Exchange Server, the Windows Inbox, and Outlook make it easy for you to quickly take advantage of all that Outlook Express has to offer. The ability to receive mail from multiple e-mail accounts, as well as the ability to create Inbox rules, helps you manage and organize your e-mail.
Outlook helps you find and organize information so that you can work seamlessly with Office applications. This helps you communicate and share information more effectively.
Powerful Inbox rules enable you to filter and organize e-mail messages. With Outlook, you can integrate and manage e-mail from multiple e-mail accounts, personal and group calendars, contacts, and tasks.
When you use Outlook with Exchange Server, you can use workgroup information sharing and workflow communications, group scheduling, public folders, forms, and enhanced Internet connectivity.
Outlook is designed for use with the Internet (SMTP, POP3, and IMAP4), Exchange Server, or any other standards-based communication system that supports Messaging Application Programming Interface (MAPI), including voice mail. Outlook is based on Internet standards and supports today’s most important e-mail, news, and directory standards, including LDAP, MHTML, NNTP, MIME, and S/MIME, vCalendar, vCard, iCalendar, and full support for HTML mail.
Outlook also offers the same import tools that are offered with Outlook Express. This enables easy migration from other e-mail clients, and offers further migration from Microsoft Mail, Microsoft Schedule+ 1.0, Microsoft Schedule+ 7.0, Lotus Organizer, NetManage ECCO, Starfish SideKick, Symantec ACT, as well as synchronization with leading Personal Digital Assistants (PDAs), such as the 3Com Palm Pilot.
In Active Directory, a collection of computer, user, and group objects defined by the administrator. These objects share a common directory database, security policies, and security relationships with other domains. In DNS, any tree or sub tree within the DNS namespace. Although the names for DNS domains often correspond to Active Directory domains, DNS domains should not be confused with Active Directory domains.
In an Active Directory forest, a server that contains a writable copy of the Active Directory database, participates in Active Directory replication, and controls access to network resources. Administrators can manage user accounts, network access, shared resources, site topology, and other directory objects from any domain controller in the forest.
A copy backup copies all selected files but does not mark each file as having been backed up (in other words, the archive attribute is not cleared). Copying is useful if you want to back up files between normal and incremental backups because copying does not affect these other backup operations.
A daily backup copies all selected files that have been modified the day the daily backup is performed. The backed-up files are not marked as having been backed up (in other words, the archive attribute is not cleared).
A differential backup copies files created or changed since the last normal or incremental backup. It does not mark files as having been backed up (in other words, the archive attribute is not cleared). If you are performing a combination of normal and differential backups, restoring files and folders requires that you have the last normal as well as the last differential backup.
An incremental backup backs up only those files created or changed since the last normal or incremental backup. It marks files as having been backed up (in other words, the archive attribute is cleared). If you use a combination of normal and incremental backups, you will need to have the last normal backup set as well as all incremental backup sets in order to restore your data.
A normal backup copies all selected files and marks each file as having been backed up (in other words, the archive attribute is cleared). With normal backups, you need only the most recent copy of the backup file or tape to restore all of the files. You usually perform a normal backup the first time you create a backup set.
Backing up your data using a combination of normal backups and incremental backups requires the least amount of storage space and is the quickest backup method. However, recovering files can be time-consuming and difficult because the backup set can be stored on several disks or tapes.
Backing up your data using a combination of normal backups and differential backups is more time-consuming, especially if your data changes frequently, but it is easier to restore the data because the backup set is usually stored on only a few disks or tapes.
- STRICT replication consistency MUST be enabled for the following to work.
- Will NOT work with LOOSE replication consistency as the data between the “DC with lingering objects” and “DC with correct data” is the same
- REPADMIN /REMOVELINGERINGOBJECTS
- repadmin /removelingeringobjects BAD-DC.ADCORP.LAN ed0c6601-28c1-47e9-b3db-5dcf291d9e31 DC=ADCORP,DC=LAN
- On the DC containing the lingering objects the event IDs 1937 (starting removal summary), 1945 (for each lingering object detected and removed) and 1939 (final removal summary) are registered in the Directory Service event log.
What are boot volume and system volume?
Ans. Boot volume: The volume that contains the Windows operating system and its support files. The boot volume can be, but does not have to be, the same as the system volume.System volume: The volume that contains the hardware-specific files that you must have to load Windows. The system volume can be, but does not have to be, the same as the boot volume. The Boot.ini, Ntdetect.com, and Ntbootdd.sys files are examples of files that are located on the system volume.

8 What is the difference between 64bit OS and 32bit OS?
Ans: Its a distributed naming system which is organized in a hierarchy. Its used in private network or internet by computers, services or entities lying within.
2) What is Domain Naming Service?
Ans: A domain naming service translates names to IP address and vice-verse. Since humans can’t remember numbers but names, this system was designed so that it helps them recognize a service or computer by name but computers are able to talk to each other using IP addresses.
3) What is forward look up?
Ans: When DNS server is queried for a name and it returns an IP address in reply, its called forward lookup. For example when I type yahoo.com in the internet explorer, the dns server returns an IP address to which a computer is able to connect.
4) What is reverse lookup?
Ans: When a DNS client queries a DNS server about an IP and the DNS server responds by providing a name is known as reverse lookup in DNS.
5) What is DNS cache?
Ans: All the queries that a DNS client does, its results are saved by it in its temporary storage so that next time when it has to find out about an IP or name, it would first look into the cache. If its not there, then only it’ll contact the DNS server. This temporary storage is called DNS cache. It helps increase the speed of name resolution for frequently queried names.
Q: How DNS query works?
Ans: The answer is a detailed one. Please visit this page to know more.
6) What are DNS forwarders?
Ans: When we setup DNS servers we want queries for internet names to be forwarded to ISP DNS so that those can be resolved by the server to which they have been forwarded and returned back to my DNS server. These servers to which the DNS queries are forwarded to are called “DNS Forwarders”.
Internet names are just one example, we could as well set up forwarders for a particular domain name as well.
7) What is Primary DNS Server?
Ans: Its the Writable copy of the DNS where the DNS database is stored. All the changes related to creation, deletion or modification of a DNS record or Zone is done on this server.
8) What is secondary DNS?
Ans: Secondary DNS servers are read only replica of primary DNS servers. They are created to distribute the load of primary DNS servers and to prevent the writable copy of the DNS to the external world. Secondary DNS servers do the same job of carrying out name resolution by using a read only copy of the primary DNS server database. They get this copy of primary DNS server database using one of the DNS Zone transfer methods. They are AXFR, IXFR and Full Zone Transfer.
IXFR – Incremental Zone Transfer.
AXFR – augmented Zone transfer.
Full/Complete Zone Transfer
To know more about Zone transfer in detail please visit this page and read thoroughly.
9) What is Active Directory Integrated DNS?
Ans: Active Directory–integrated DNS enables Active Directory storage and replication of DNS zone databases. Windows 2000 DNS server, the DNS server that is included with Windows 2000 Server, accommodates storing zone data in Active Directory. When you configure a computer as a DNS server, zones are usually stored as text files on name servers — that is, all of the zones required by DNS are stored in a text file on the server computer. These text files must be synchronized among DNS name servers by using a system that requires a separate replication topology and schedule called a zone transfer However, if you use Active Directory–integrated DNS when you configure a domain controller as a DNS name server, zone data is stored as an Active Directory object and is replicated as part of domain replication.
10) What is stand alone DNS Server?
Ans: A non AD integrated DNS can be termed as standalone DNS server. Its the only DNS server in an environment.
11) How DNS can do load balancing?
Ans: DNS can do load balancing by using the following methods:
1) DNS Round Robin
2) Using weights on DNS records. For example we can define weight on each MX record to define how much of load we want a particular server to handle.
12) What is Secondary Zone?
Ans: The zone hosting the read only copy of a Primary DNS server’s writable copy of Zone is called a secondary zone.
13) What is SRV record?
Ans: The SRV RR identifies the host(s) that will support particular services. The MX RR is a specialised example of service discovery while the SRV RR is a general purpose RR to discover any service.
14) What is A record and PTR record?
Ans: “A” records are host records where a name is mapped to the IP address assigned to it. A “PTR” records where IP addresses are mapped to a name.
15) What is a Stub Zone?
Ans: A stub zone is a copy of a zone that contains only those resource records necessary to identify the authoritative Domain Name System (DNS) servers for that zone. A stub zone is used to resolve names between separate DNS namespaces. This type of resolution may be necessary when a corporate merger requires that the DNS servers for two separate DNS namespaces resolve names for clients in both namespaces.
A stub zone consists of:
The start of authority (SOA) resource record, name server (NS) resource records, and the glue A resource records for the delegated zone.
16) What is a delegated DNS zone? When do we use it?
Ans: Delegated DNS zones are created when we want the name resolution of subdomains or child domains to be broken up with in DNS. For more details please visit this page.
19) How to troubleshoot Active Directory related DNS problems using DCDiag tool?
Ans: Please find the steps here. Do look for part 2 of this youtube video.
20) New features of DNS in Windows 2008?
- Background zone loading: DNS servers that host large DNS zones that are stored in Active Directory Domain Services (AD DS) are able to respond to client queries more quickly when they restart because zone data is now loaded in the background.
- IP version 6 (IPv6) support: The DNS Server service now fully supports the longer addresses of the IPv6 specification.
- Support for read-only domain controllers (RODCs): The DNS Server role in Windows Server 2008 provides primary read-only zones on RODCs.
- Global single names: The GlobalNames zone provides single-label name resolution for large enterprise networks that do not deploy Windows Internet Name Service (WINS). The GlobalNames zone is useful when using DNS name suffixes to provide single-label name resolution is not practical.
- Global query block list: Clients of such protocols as the Web Proxy Auto-Discovery Protocol (WPAD) and the Intra-site Automatic Tunnel Addressing Protocol (ISATAP) that rely on DNS name resolution to resolve well-known host names are vulnerable to malicious users who use dynamic update to register host computers that pose as legitimate servers. The DNS Server role in Windows Server 2008 provides a global query block list that can help reduce this vulnerability.
