When checking to see if a particular name is registered on the Internet your computer consults a database that is maintained on what server?
The Domain Name System (DNS) server is consulted to check to see if a name is registered on the internet. This server translates domain names to IP addresses, to locate computer devices and services.
What is a domain check and how is it useful?
A domain check is when a system checks to see if a domain is being used currently. It is useful to know whether or not the domain has been taken or the steps to obtaining it.
What is the process of acquiring an EU domain registration?
Any company or person located in the European Union can register a .eu domain. First, you need to check to see if your desired .eu domain is already registered. If not, then you can register your .eu domain name online.
How can I check for the availability of domain names?
Usually, the domain selling website will have a availability check handy at the time of the domain purchase. Or you can simply type your desired domain into the address bar to see if a website comes up. If it does, then the domain is taken.

Describe the importance of DNS to AD?
When you install Active Directory on a server, you promote the server to the role of a domain controller for a specified domain. When completing this process, you are prompted to specify a DNS domain name for the Active Directory domain for which you are joining and promoting the server.If during this process, a DNS server authoritative for the domain that you specified either cannot be located on the network or does not support the DNS dynamic update protocol, you are prompted with the option to install a DNS server. This option is provided because a DNS server is required to locate this server or other domain controllers for members of an Active Directory domain
Which commmand is used to find DNS server's information about a domain name?
Find All Name Servers GOALS: Find every name server that may be authoritative for your domain. Make sure that all are authoritative, and that WHOIS has a list of all of them (and no others). BACKGROUND: Every domain name is required to have a primary nameserver (only one), and at least one secondary nameserver. This is to help ensure that all domains are reachable. For example, if you have 3 separate offices, and one of them suffers a disaster, that shouldn't prevent people from being able to reach the other two offices. The WHOIS database lists all the authoritative nameservers (ones that get updated automatically when you make changes) for your domain. This list gets sent to the root server for your Top Level Domain (such as .com). Anyone in the world trying to reach your domain will get that list, and go to one of the nameservers to resolve a subdomain within your domain. Step 2a: Find out what the root servers think your nameservers are To do this, you will need to use a program that can generate DNS requests (such as NSLOOKUP on Windows or DIG). My favorite program for this is Sam Spade. Or, you can go to a web site that allows these requests, such as http://www.samspade.org/. First, find the primary root server for your Top Level Domain (such as .com if you have the domain example.com). With NSLOOKUP, you can type "set type=NS" (to get the NS, or nameserver, records) and then enter your top level domain ("com" or "uk" or whatever). You will get a list of root nameservers. Type "server " followed by the first nameserver in the list (for example, "server a.root-servers.net"). Then, enter your domain name ("example.com"). Now, you will have a list of servers that the root servers think are authoritative for your domain. With DIG, enter your top level domain ("com") as the domain to look up (or type "dig com@default.dnsserver" where "default.dnsserver" is your normal DNS server). Look at the "NS" entries in the results, and take the top one, and enter it as the nameserver to use. Then, as the domain to look up, enter your domain name (or, type "dig example.com@a.root-servers.net", where your domain goes before the "@" and the root server goes after the "@"). This should just return the name servers for your domain, but make sure just to look at entries with " NS " in them. Problem? If there are any nameservers listed here that are NOT listed in WHOIS, or there are any nameservers listed in WHOIS that are NOT listed here, there is a problem. Contact the company that gave you your domain name for help. Add these to your list of nameservers from WHOIS that you got in Step 1. Step 2b: Find out what your name servers say your nameservers are For this step, do exactly what you did in Step 2a, except this time use the first one of the name servers you have written down as the DNS server to use, and use your domain name as the domain to look up. Using NSLOOKUP, type "server nameserver.example.com" (where nameserver.example.com is the first name server on the list you wrote down), then "set type=ns", and then enter your domain name. If there are any name servers listed here that are not on your list, add them to the list. Or, using DIG, enter the first name server you wrote down as the name server to use, and then your domain name as the domain to look up. Or, from the command line, type "dig example.com@nameserver.example.com". If there are any name servers listed here that are not on your list, add them to the list (only look at entries with " NS " in them). Problem? If any name server you check here returns a name server that was NOT listed in WHOIS, it is called a "missing nameserver", and is an error. If the name server listed is authoritative for your domain (see steps below), it MUST (RFC882 p.25) be added to the WHOIS listing. If it is NOT authoritative for your domain, it MUST be taken out of the nameserver it was listed in. Problem? If any name server you check here does NOT return one of the name servers listed in WHOIS, there is a problem. If the name server listed in WHOIS IS authoritative for your domain (see steps below), it MUST be added to your nameservers. If it is NOT authoritative, it MUST be taken out of WHOIS (but you MUST have at least 2 nameservers listed in there). Repeat this step for EVERY name server on your list -- even ones you may have just added. Step 2c: Test every name server You need to make sure that every name server on your list is authoritative for your domain. With DIG, use the first name server on your list as the domain server to use, and enter your domain name as the domain to look up (or, from the command line, type "dig example.com@nameserver.example.com"). You should see "Authoritative answer" (or something similar) if it is authoritative, or "Non-authoritative answer" if it is not. Problem? If the name server is NOT authoritative for your domain, you have a "lame delegation." If this server is not authoritative, and it is listed as an NS record in your domain (step 2b), it MUST be taken out. If this server is not authoritative, and it is listed in WHOIS, it MUST be taken out (but, you MUST also have at least 2 name servers listed in WHOIS). Step 2d: Sanity Checks * You MUST have ONLY ONE primary nameserver. You will check this later in the step for SOA (Start of Authority) records, where the primary server is listed. * You MUST have AT LEAST ONE secondary nameserver. That means that WHOIS, the root servers, and all your name servers MUST list at least two name servers that are authoritative for your domain. You may have more than one secondary nameserver (4 to 7 SHOULD be the maximum). * Your secondary nameserver(s) MUST get their information directly from your primary nameserver, and check it periodically (how often is based on the SOA record fields) for updates.
Requirement of dns in domain controler?
When you install Active Directory on a member server, the member server is promoted to a domain controller. Active Directory uses DNS as the location mechanism for domain controllers, enabling computers on the network to obtain IP addresses of domain controllers. During the installation of Active Directory, the service (SRV) and address (A) resource records are dynamically registered in DNS, which are necessary for the successful functionality of the domain controller locator (Locator) mechanism. To find domain controllers in a domain or forest, a client queries DNS for the SRV and A DNS resource records of the domain controller, which provide the client with the names and IP addresses of the domain controllers. In this context, the SRV and A resource records are referred to as Locator DNS resource records. When adding a domain controller to a forest, you are updating a DNS zone hosted on a DNS server with the Locator DNS resource records and identifying the domain controller. For this reason, the DNS zone must allow dynamic updates (RFC 2136) and the DNS server hosting that zone must support the SRV resource records (RFC 2782) to advertise the Active Directory directory service. For more information about RFCs, see DNS RFCs. If the DNS server hosting the authoritative DNS zone is not a server running Windows 2000 or Windows Server 2003, contact your DNS administrator to determine if the DNS server supports the required standards. If the server does not support the required standards, or the authoritative DNS zone cannot be configured to allow dynamic updates, then modification is required to your existing DNS infrastructure.
How do you check if a mail server is running?
In a terminal, type "ps aux | grep [insert name of mail server]". If you see more than one process listed, the server is running. Otherwise, it is not.
