Other possible names for a virtual server would be network server, name based hosts, or the most common...just 'server' on it own. Your IP address is assigned depending on what server you use.

• No firewall provides protection against viruses, continuously new viruses and new methods are released everyday which affect the system.
• Firewall can't give protection against all attacks which don't pass through firewall.
• Firewall reflects overall security level of network, an architecture which depends on one security mechanism or one method has a point of failure which may open the system to intruders.
• If firewall is incorrectly configured it can't tell you the problem, only professional want to minimize the risk using their experience.
• It is highly difficult for firewall if someone hacked into your network to notify you, for which you need separate monitoring tools.
• If a hacker masquerades like trusted user or employee it is highly impossible for firewall to protect from such type of hackers, because today we have numbers of ways to find user names and passwords.
• Firewall can't protect system from malicious codes also.
• Firewalls don't encrypt e-mail messages or confidential documents which are sent inside the organization or outside of the organization.
• Firewalls can't give 100% security to the system or organization.
• Firewall can't find other vulnerabilities which might allow hacker to access internal network.
• Firewall cannot decide which is legitimate decision and which is not, it works entirely based on the set of rules and criteria and policy mentioned by the management part during the planning of security policy.

The global catalog contains a complete replica of all objects in Active Directory for its Host domain, and contains a partial replica of all objects in Active Directory for every other domain in the forest. The global catalog is a distributed data repository that contains a searchable, partial representation of every object in every domain in a multidomain Active Directory forest. The global catalog is stored on domain controllers that have been designated as global catalog servers and is distributed through multimaster replication. Searches that are directed to the global catalog are faster because they do not involve referrals to different domain controllers. In addition to configuration and schema directory partition replicas, every domain controller in a Windows 2000 Server or Windows Server 2003 forest stores a full, writable replica of a single domain directory partition. Therefore, a domain controller can locate only the objects in its domain. Locating an object in a different domain would require the user or application to provide the domain of the requested object. The global catalog provides the ability to locate objects from any domain without having to know the domain name. A global catalog server is a domain controller that, in addition to its full, writable domain directory partition replica, also stores a partial, read-only replica of all other domain directory partitions in the forest. The additional domain directory partitions are partial because only a limited set of attributes is included for each object. By including only the attributes that are most used for searching, every object in every domain in even the largest forest can be represented in the database of a single global catalog server.

DHCP is used to assign IP addresses to computers joining a network. Many ISPs use DHCP to give their customers IP addresses. When DHCP assigns you an IP address, or sends you a "DHCP certificate," it "leases" the IP address to you for a period of time. When this lease runs out, the DHCP certificate becomes "stale," and you must request a new one. Usually your computer will do this automatically and you won't even know it happened. This terminology is a bit strange. I can guess what you mean by a "stale" DHCP "certificate" but I'm not sure that everyone would. It sounds like something that someone made up. I could be wrong. -DJ Craig

Use Universal distribution groups in a multiple-domain environment. The membership of universal distribution groups is replicated to each global catalog server in each domain

standard secondary zone

During ordinary operation, the white space in the Active Directory database file becomes fragmented. Each time garbage collection runs (every 12 hours, by default), white space is automatically defragmented online to optimize its use within the database file. The unused disk space is thereby maintained for the database; it is not returned to the file system.

Two DNS application directory partitions below the forest root domain are automatically created by the DNS Server service when the computer restarts after the Active Directory Installation Wizard has finished. One application directory partition is created for the forest, ForestDnsZones, and one for the domain, DomainDnsZones. You can use the DNS administrative tool or the dnscmd.exe command-line tool, located in the \Support\Tools directory on the Windows Server 2003 product CD, to use these application directory partitions for DNS zone storage.

If you are installing an additional domain controller in an existing forest, the domain controller holding the domain naming operations master role must be online, available, and running Windows Server 2003 for these application directory partitions to be created. If the domain naming master is unavailable or is running Windows 2000, the DNS Server service will attempt to create the application directory partitions again at a later time.

REPADMIN

REPADMIN.EXE is a command line tool used to monitor and troubleshoot replication on a computer running Windows. This is a command line tool that allows you to view the replication topology as seen from the perspective of each domain controller. It performs the following actions: * Checks replication consistency between replication partners.

* Monitors replication status.

* Displays replication metadata.

* Forces replication events.

* Knowledge Consistency Checker (KCC) recalculation

* Important Usage

** In order to replicate the new NS record to all the domain controllers, run the REPADMIN /syncall command from the command prompt.

** To immediate replicate the AD information, choose either of two- From the AD Sites and Services console, select the existing connection objects and force replication. Or, use REPADMIN.EXE to force replication between the site connection objects.

** Use the REPADMIN tool to synchronize new user information between all sites to enable new users to log on to the domain in a remote site. Other Answer REPADMIN is a built-in Windows diagnostic command-line utility that works at the Active Directory level. Although specific to Windows, it is also useful for diagnosing some Exchange replication problems, since Exchange Server is Active Directory based. REPADMIN doesn't actually fix replication problems for you. But, you can use it to help determine the source of a malfunction.
