DNS Server
The Mail server will be using fedora as the OS. First step will be to install fedora on the server. After successful install there are 3 packages that need to be installed. The first package will be the bind package. Next will be the bind-utils and bind-chroot packages.
After successful install of all packages we will start with adding files to the chroot directory that will be implemented for security. We will do this in anticipation if anyone hacks into the server they will be confined to that directory. To do this a copy of the named.config, named.rfc1912.zones, and the named.root.hints files will made in the /var/named/chroot/etc directory.Also copy the default zone files from/user/share/doc/bind/sample/var/named into var/named/chroot/var/named directory. In the /etc/named.config file we need to add the DNS server Birch.company.com with the ip address 206.207.208.12, mail server Cedar.company.com 206.207.208.11, and web server Aspen.company.com 206.207.208.10 to the list of servers to be added to the DMZ zone.. In the /etc/resolve.config file we need to point the DNS server to quiry the ISP DNS 82.83.84.85 for unknown names or domains. This setup will allow clients on the Corp. side to query the DMZ DNS which will in turn query the ISP DNS for any name resolution and protect the internal network from being compromised.
In addition to the using chroot we will also implement SELinux as addition security. To ensure DNS will run automatically at system boot the runlevel will be set to runlevel 3 using the chkconfig...

Dns in Windows 2003 Server

...Introduction to DNS in Windows Server 2003 There are three scenarios in which your network needs DNS. • Firstly, to find Active Directory resources such as Global Catalog Servers and also Domain Controllers that authenticates Logon or Kerberos requests. • Secondly to locate pages on the internet, • Thirdly, mundane task for example, connecting to a printer share. DNS makes it possible for clients to access network resources using alphanumeric names rather than pure IP addresses. Unlike WINS, DNS is hierarchical, with advent of Windows 2000 DNS became dynamic DNS. In practical terms, it means that clients can update their own DNS Server records automatically, thus reducing the administrative load. The killer reason for implementing DNS is that Active Directory relies on DNS for finding Global Catalog, Kerberos and Logon Servers. Before you install DNS on a production network you need to answer a whole series of questions. For example Will your DNS name match our email domain? Who will be in charge of DNS, you or must you rely on a Unix department? One 'Litmus Test' for a difficult topic is the number of specialist terms a component uses. My rule is the more unusual words and acronyms, the more difficult the subject is to master. DNS passes this ' difficulty ' test with flying colours. For instance you need to understand, Namespace, Authoritative, Recursive, and Incremental to name just a few of the DNS keywords. As you learn about DNS Server watch out......

...for forwarding DNS queries for external DNS names to DNS servers outside the network and conditional forwarders can be used to forward queries according to specific domain names. When we designate a DNS server as a forwarder, then that forwarder is responsible for handling external traffic. Which limits DNS server’s exposure to the internet. In less time, a forwarder resolves a large number of external DNS queries using cached data built by it. This decrease the response time of DNS server. Server which doesn’t have forwarder setup. That server can use root hints to resolve queries. Conditional forwarder:- Conditional forwarders are using to forward queries according to domain names by DNS server. A DNS servers can be configure to forward queries to different forwarders according to the specific domain names that are contained in the queries is better than having a DNS server forward all queries it cannot resolve locally to a forwarder. When we configure the DNS server in one internal namespace to forward all queries to the authoritative DNS server in a second internal namespace, Conditional forwarders enable name resolution between the two namespaces without performing recursion on the DNS namespace of internet. This performance enhances name resolution which also avoids DNS servers performing recursion to our internal root for different namespaces within the network. How to configure Forwarder:- There are two ways to configure forwarder in DNS server. 1. A) We can...

Dns Role Server

...DNS Server Role Updated: January 21, 2008 Domain Name System (DNS) is a system for naming computers and network services that is organized into a hierarchy of domains. TCP/IP networks, such as the Internet, use DNS to locate computers and services through user-friendly names. To make using network resources easier, name systems such as DNS provide a way to map the user-friendly name for a computer or service to other information that is associated with that name, such as an IP address. A user-friendly name is easier to learn and remember than the numeric addresses that computers use to communicate over a network. Most people prefer to use a user-friendly name—for example, sales.fabrikam.com—to locate an e-mail server or Web server on a network rather than an IP address, such as 157.60.0.1. When a user enters a user-friendly DNS name in an application, DNS services resolve the name to its numeric address. What does a DNS server do? A DNS server provides name resolution for TCP/IP-based networks. That is, it makes it possible for users of client computers to use names rather than numeric IP addresses to identify remote hosts. A client computer sends the name of a remote host to a DNS server, which responds with the corresponding IP address. The client computer can then send messages directly to the remote host's IP address. If the DNS server does not have an entry in its database for the remote host, it can respond to the client with the address of a DNS server that...

...As far as the issue at hand there might be an issue with some of the hosts not being authorized through DHCP in the active directory. You can do this by going into the device and going to the console tree, click DHCP; on the Action menu, click Manage authorized servers (the Manage Authorized Servers dialog box appears); Click Authorize; when prompted, type the name or IP address of the DHCP server to be authorized, and then click OK. This can be done on the devices that are not receiving the new address and DHCP will automatically configure the rest. In the command line, type in ipconfig / all to allocate if the devices that are not working have any IP address at all and see if DHCP is enabled. This will tell you if the device is using DHCP. Since the DHCP server was changed, a DHCP server can only service requests for a scope that has a network ID that is the same as the network ID of its IP address. You have to make sure that the DHCP server IP address falls in the same network range as the scope it is servicing. For example your IP address range is 192.168.0.200 through 192.168.0.225, a server with an IP address in the 192.168.0.0 network cannot assign addresses from scope 10.0.0.0. Using ipconfig in the command line will tell what IP address is being used. If it is not the same on the devices that are working then that is where the problem is. Also, the computers not working could use a simple re-boot and maybe the addresses will be automatically assigned or......

The Role of Te Dns Server

...System (DNS) is a standard technology for managing the names of Web sites and other Internet domains. DNS technology allows you to type names into your Web browser and your computer to automatically find that address on the Internet. A key element of the DNS is a worldwide collection of DNS server. The structure of the DNS is a hierarchical namespace allowing the uniqueness of a name to be guaranteed in a tree structure, like UNIX file systems. A system of distribution servers enabling namespace to be made available. a client system making it possible to "resolve" domain names, for example interrogate the servers to find out the IP address corresponding to a name. It is necessary because DNS allows all of these numbers and configuration options to be changed and updated as networks get more and more complicated without requiring the user to keep track of everything. A user doesn't have to send email to different people in the same company. They only need to remember the domain name; even as new servers are added and old servers are removed or replaced. There are two types of DNS servers – primary and secondary. A primary master name server reads data for the domain zone from a file located on the web server of the hosting account. This server usually also sends information to the secondary server as well. A secondary DNS server, also called a slave server or simply a slave, receives zone data from the primary server automatically after starting. In Microsoft's DNS manager......

...starting the next task. To command the computer to wait until the program finishes, the start command used with the /wait switch or /w for short is used. For example to install a DNS Server role the command line input would be start /w ocsetup DNS-Server-Core-Role. 2. To remove a Server role the switch /uninstall is used. The switch is typed at the end of a command line input of the start, /w, ocsetup and then name of the role which is to be removed. For an example, if say the Server role of DHCP was needed to be uninstalled the command line input would be start /w ocsetup DHCPServerCore /uninstall. 3. To start and configure the DHCP Server role once it has been installed two commands will be needed. To configure the service the command to input would be sc config dhcpserver start= auto. This command will bring up the ChangeServiceConfig function for the DHCP Server role. To start the DHCP Server role the command line input would be net start dhcpserver. 4. To configure a DNS zone once a DNS Server role has been installed the command line input to use is dnscmd. The dnscmd command is used in conjunction with the / command followed by the DNS configuration that is to be changed. For example if the DNS server cache need to be cleared the command line input would be dnscmd...

...*part one talk about DNS servers. What are they what do they do basic configuration and variation of configuration. As the network administrator for Contoso, Ltd to resolve the issue of users on the company network reporting that they can use host names to connect to computers on the local private network, but they cannot use host names to connect to Internet destinations you have a few options. The action that will take the least amount of administrate effort to enable network users can connect to the Internet host names would be to configure NS2 and NS3 to use NS1 as a forwarder. A DNS forwarder is a DNS server that performs DNS queries on behalf of another DNS server (Shinder.T 2005). With this setup one would configure the firewall used by NS1 to allow only one DNS server to communicate with the internet. After you configure NS2 and NS3 to forwarder all queries that cannot be resolved internally will be forwarded to NS1. Because of the large amount of traffic going through NS1 the server will build a large cache of DNS data, overtime this data will allow the DNS server to process request faster(Book). Another option to solve the issue of users on the company network reporting that they can use host names to connect to computers on the local private network, but they cannot use host names to connect to Internet destinations is to configure all DNS servers to send queries outside of a network using their root hints. This is not the most desirable configuration......

...support the size, security needs and growth possibilities of an organization. One area that will impact the entire organization for years relates to using/installing Domain Name System (DNS) and Dynamic Host Configuration Protocol (DHCP). DNS and DHCP services can be set up in an office by installing the correct equipment or through the ISP that the organization is using. Knowing what is best for the organization should be based on their current size and equipment needs. A small office with only 2 computers would not require new equipment to be installed. In this size office I would recommend statically assigning the IP addresses to the two computers and using the DNS that is on the ISP network. For an office a little bigger, with 5 computers, I would recommend that they install a router/hub in-one device which can also act as a DHCP server. These all-in-one devices are typically less than $200, will add firewall protection and have ports to connect the computers via an Ethernet connection which will allow better internet access. I would still recommend that this office use the DNS on their ISP’s network. For a larger organization with over 25 computers, I would recommend that they install a Server which will have both DNS & DHCP options. With the size of this organization, having the DNS & DHCP on site will allow for quicker response times when using the internet and the ability to not have to manage which IP addresses are assigned to which...

You may ask why only one server? The simple answer is this I would setup the email server, print server and the office server would all be set as cloud servers this would save us on space as well as allow employees with the right permission to access the servers from any location via hardwired or wireless. How would I set up the group polices? Let’s star with the BC (Bereavement counselors) and the PCC (practitioner clinical counselor manager) I would set them up as local group with permission save to and access the print server and office server this is would allow them to access patient records from the server as well as save then for the doctors and nurses to access later. Also the TC (intake coordinator) and the VC (volunteer counselor) would be set up as a local group with the same access and permission as the BC this is due to the fact that like the BC I believe that due to the fact that thy are only inputting information and updating information, I see no need to allow them to have full access to system this to groups would have NTFS list folder contents permission...
