Windows Server 2003

It means that, there was some problem in the Web server and it prevented it from satisfying the request it received. Usually it happens when the server crashes or when there is a database issue etc.

Be specific please

If the pan was dropped, it takes about 4 quarts to fill it. If it was overhauled, it takes about 13 quarts to fill the convertor and everything..

The are called A, B, C, ...

These are the highest level of the DNS hierarchy. Ultimately, any DNS requests that can't be solved at a lower level (through the use of a cache) is traced back to those 13 root servers.

1)On the Active Directory tab, click Create synchronization rule.

2)Enter the server address for your Active Directory server and a user name and password that provide at least read access, then click Next.

3)elect the Active Directory container that you want to import, then click Next.

4)Select the target policy domain for importing the structure, then click Next.

5)Click Done to run the synchronisation rule.

The main group type found in active directory is the security group.

Windows Explorer can only handle up to 256 characters in a path and filename. This causes problems when trying to delete files that have been created in a share.

You can use this tool to delete long path file

The MAC address is the LAN/Ethernet card address there is no specfic Mac address for active directoy. Each server/PC in the world has its own unique mac address.

A server hosts resources that others can request or use. Therefore, anyone that is requesting information or a service that is on a server is using it. Traditionally these are called clients.

At the DHCP server, you would create an address reservation. To do so, you need to know the host's MAC address for its network interface.

Small Business Server has many benefits including a preconfigured intranet which allows the ability to share contacts, calendars, etc. On the downside, it has built in limitations such as the number of users and the use of only one domain.

No, you can't. Some of hidden folders are system and required for OS to run.

Backing up Active Directory is essential to maintain an Active Directory database. You can back up Active Directory by using the Graphical User Interface (GUI) and command-line tools that the Windows Server 2003 family provides.

You frequently backup the system state data on domain controllers so that you can restore the most current data. By establishing a regular backup schedule, you have a better chance of recovering data when necessary. To ensure a good backup includes at least the system state data and contents of the system disk, you must be aware of the tombstone lifetime. By default, the tombstone is 60 days. Any backup older than 60 days is not a good backup. Plan to backup at least two domain controllers in each domain, one of at least one backup to enable an authoritative restore of the data when necessary. System State Data

Several features in the windows server 2003 family make it easy to backup Active Directory. You can backup Active Directory while the server is online and other network function can continue to function. System state data on a domain controller includes the following components: Active Directory system state data does not contain Active Directory unless the server, on which you are backing up the system state data, is a domain controller. Active Directory is present only on domain controllers.

The SYSVOL shared folder: This shared folder contains Group policy templates and logon scripts. The SYSVOL shared folder is present only on domain controllers.

The Registry: This database repository contains information about the computer's configuration.

System startup files: Windows Server 2003 requires these files during its initial startup phase. They include the boot and system files that are under windows file protection and used by windows to load, configure, and run the operating system.

The COM+ Class Registration database: The Class registration is a database of information about Component Services applications.

The Certificate Services database: This database contains certificates that a server running Windows server 2003 uses to authenticate users. The Certificate Services database is present only if the server is operating as a certificate server.

System state data contains most elements of a system's configuration, but it may not include all of the information that you require recovering data from a system failure. Therefore, be sure to backup all boot and system volumes, including the System State, when you back up your server. Restoring Active Directory

In Windows Server 2003 family, you can restore the Active Directory database if it becomes corrupted or is destroyed because of hardware or software failures. You must restore the Active Directory database when objects in Active Directory are changed or deleted. Active Directory restore can be performed in several ways. Replication synchronizes the latest changes from every other replication partner. Once the replication is finished each partner has an updated version of Active Directory. There is another way to get these latest updates by Backup utility to restore replicated data from a backup copy. For this restore you don't need to configure again your domain controller or no need to install the operating system from scratch. Active Directory Restore Methods

You can use one of the three methods to restore Active Directory from backup media: primary restore, normal (non authoritative) restore, and authoritative restore. Primary restore: This method rebuilds the first domain controller in a domain when there is no other way to rebuild the domain. Perform a primary restore only when all the domain controllers in the domain are lost, and you want to rebuild the domain from the backup.

Members of Administrators group can perform the primary restore on local computer, or user should have been delegated with this responsibility to perform restore. On a domain controller only Domain Admins can perform this restore.

Normal restore: This method reinstates the Active Directory data to the state before the backup, and then updates the data through the normal replication process. Perform a normal restore for a single domain controller to a previously known good state.

Authoritative restore: You perform this method in tandem with a normal restore. An authoritative restore marks specific data as current and prevents the replication from overwriting that data. The authoritative data is then replicated through the domain.

Perform an authoritative restore individual object in a domain that has multiple domain controllers. When you perform an authoritative restore, you lose all changes to the restore object that occurred after the backup. Ntdsutil is a command line utility to perform an authoritative restore along with windows server 2003 system utilities. The Ntdsutil command-line tool is an executable file that you use to mark Active Directory objects as authoritative so that they receive a higher version recently changed data on other domain controllers does not overwrite system state data during replication.

SOA Resource Records

Every zone contains a Start of Authority (SOA) resource record at the beginning of the zone. SOA resource records include the following fields:

*

The Owner , TTL , Class , and Type fields, as described in "Resource Record Format" earlier in this chapter.

*

The authoritative server field shows the primary DNS server authoritative for the zone.

*

The responsible person field shows the e-mail address of the administrator responsible for the zone. It uses a period (.) instead of an at symbol (@).

*

The serial number field shows how many times the zone has been updated. When a zone's secondary server contacts the master server for that zone to determine whether it needs to initiate a zone transfer, the zone's secondary server compares its own serial number with that of the master. If the serial number of the master is higher, the secondary server initiates a zone transfer.

*

The refresh field shows how often the secondary server for the zone checks to see whether the zone has been changed.

*

The retry field shows how long after sending a zone transfer request the secondary server for the zone waits for a response from the master server before retrying.

*

The expire field shows how long after the previous zone transfer the secondary server for the zone continues to respond to queries for the zone before discarding its own zone as invalid.

*

The minimum TTL field applies to all the resource records in the zone whenever a time to live value is not specified in a resource record. Whenever a resolver queries the server, the server sends back resource records along with the minimum time to live. Negative responses are cached for the minimum TTL of the SOA resource record of the authoritative zone.

yes users are the important part of active directory as the users are assigned the permission to use the resources, groups, printers .We can assign users to a group and apply permission on them we can put them in OU and apply restriction /permission etc.Without users there is no meaning of resources.
