How to Publish a DNS server in Internet Security and Accelerate (ISA) Server

This article will tell you how to publish a DNS server by using the Microsoft Internet Security and Acceleration (ISA) Server.

If you want to publish a DNS Server which is hosted on the ISA Server, then you have to create a new server publishing rule. For doing this, follow these steps:

• You have to start the ISA Server Management tool.
• Then you have to elaborate the Server Name, where Server Name is the name of your ISA Server computer.
• After this, click on the Firewall Policy.
• Click on Create a New Server Publishing Rule after clicking on the Tasks tab.
• After performing this, in the Server publishing rule name box, you have to type a descriptive name for this rule
• Then click on the Next. If you want to publish the DNS Server,
• Then write its IP address in the Server IP address box.
• You have to type the IP address of the ISA Server computer's internal interface, in case the DNS server is hosted on the ISA Server computer.
• Then in the Selected protocol list, click on DNS Server and then click on the Next.

If you want that ISA Server to listen on for DNS queries, then you have to click to select the check box of the network list. For example, click to select the External check box, in case you want to enable external users to submit queries to your DNS server.
Now, if you want to select a particular IP address that ISA Server listens on:

• Then click on the Address.
• Then click on the opted IP addresses on the ISA Server computer in the selected network.
• After this, click on the IP address that you want ISA Server to listen on, click on Add,
• Then click on OK. After performing this,
• Click on Next and then click on the Finish.
• Click on the Apply to save your changes and to update the firewall policy and then click OK.

Finding out the Best DNS Server

The Domain Name System (DNS) is a naming system which is useful for the devices which are either using or participating in Internet. It translates the domain names of these participants into a form which is simple and useful for users. Now let us see what this form is? This form is basically composed of the numerical identifiers. These numerical identifiers are linked with the networking devices for the intention of locating these devices globally. DNS is also useful for the Internet because it can translate the user friendly domain names into the IP addresses.

If you want to calculate the DNS server addresses for your IP, then you can use a website for this purpose. Although this project is under development, it gives satisfactory results. For getting the best DNS servers for your IP follow these steps:

• You have to open the website http://dnsserverlist.org/.
• Then on this website, search for a rectangular box in the middle part of the website. On this rectangular box the calculated DNS servers were written.
• You have to open your Local Area Network (LAN) in the Network Connections.
• Then right click on the LAN and select Properties.
• Then highlight Internet Protocol (TCP/IP) and click on the Properties. Choose the option Use the following DNS server addresses and then click on the Advanced.
• Then move to the DNS tab and click on Add. After doing this, you have to add the three DNS server addresses which were automatically created by at the website dnsserverlist.org.
• Then click on the OK for coming out of the LAN. Now, you will get the best DNS servers for your IP.

Alteration in Terminal Server's Listening Port

As we have described earlier about DNS Server Installation in Windows Server 2003 that is Domain Name Server installation in Windows Server 2003 and now will describe how to alter listening port of your Server.

It is a well-known fact that TCP port 3389 is used by Terminal Server and Windows 2000 Terminal Services for client connections. Alteration in this port is not recommended by Microsoft. But you can change this port. You have to perform this task carefully, otherwise you will face serious problems.

You have to give more concentration while modifying the registry. If you want to change the default port, then you have to follow these steps:

• You start with the task of running Regedt32 and go to this key, HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp.


• Then you have to find the port number subkey and notice the value of 00000D3D, hex is for 3389.


• After this, you have to change the port number in Hex and save the new value

If you want to change the port for a particular connection on the Terminal Server, then follow these steps:

• You have to run Regedt32 and go to this key, HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Terminal Server\WinStations\connection.


• After this, you have to find the port number subkey and notice the value of 00000D3D, here hex is for 3389.


• Then you have to change the port number in Hex and save this new value.

After performing this, you have to make alteration in the Port on the Client Side. Follow these steps to perform this:

• You have to open Client Connection Manager.


• Then on the File menu, click on New Connection and then create the new connection. After executing the wizard, you will view a new connection listed there.


• Then you have to ensure that new connection is highlighted. After this, on the File menu, click Export.


• Then you have to edit the .cns file using Notepad. You have to make modifications in the server port, Server Port=3389 to Server Port= new port number, that you had specified on Terminal Server.


• Now import the file back into Client Connection Manager. Then you will be demanded to overwrite the current one.


• If it has the same name, then overwrite it.

In this way, you will receive a client that has the correct port settings to match your Terminal Server settings. Hope it will help you out, Don’t Forget to subscribe to my blog for more tips and tricks on server and Microsoft Server Support Services

Installation of DNS Server in Windows Server 2003

When you browse Internet, you always write alphanumeric address in the address bar. You write these type of addresses because these are easy to remember. The main point is that any server address is in the form of IP address. Then there arises the need of translating these alphanumeric addresses in the IP addresses. Here comes the role of DNS Server. DNS Server does the task of translating the alphanumeric address into the IP address. This server is required when you write any website address in the address bar or you click on any link. Before the installation of DNS Server, you should have the information about your domain name, the IP address and host name of each server for which you want to provide name resolution.

If you want to configure your computer as a DNS Server, then the following conditions should be fulfilled:

Your operating system should be configured in the correct way. DNS service is based on the correct configuration of the operating system and its services, in case you are using the Windows Server 2003 family. You have to allocate the available disk space. All the existing disk volumes should use the NTFS file system.

If you want to install DNS Server, then follow these steps:

Click on the Start, click on Control Panel and then click on the Add or Remove Programs. After this, click on Add/Remove Windows Components. Then open the Windows Components Wizard. In the Components, pick out the Networking Services check box and then click on the Details. In the Subcomponents of Networking Services, pick out the Domain Name System (DNS) check box, click on OK and then click on the Next. If you are prompted, then type the full path of the distribution files and then click on OK. In this way DNS Server will be installed on your system.

Installation and Setup of BIND DNS Server

DNS is stands for "Domain Naming Services".It is very crucial server or services specially when you want ot access your server from internet.The reason for this is that domain names are much easier to type for users, and easier to remember. Thus, you need a DNS server if you plan on having Internet users connect to your server. The standard DNS server is the Berkeley Internet Name Domain (BIND). BIND is available through the Internet Software Consortum, or ISC at isc.org. In addition, BIND should be available through your distribution. In the case of BIND, I would recommend downloading the packages through your distribution's website. Before you may use a domain name, you must first register it, which there are several services available to register domain names. Once installed, you should then edit /etc/named.conf, and add the following information to it:

zone "desireddomain.com" {

type master;

file "desireddomain.db";

};
You will of course replace the "desireddomain" strings as appropriate with your new domain name. This entry tells the named service that this server is the master server (with DNS, 2 DNS servers are required, for redundancy). Now then, we will now create the "desireddomain.db" file, which should be placed in the working directory of named, which is specified in the beginning of /etc/named.conf. In this file, we should place the following information:

IN SOA nameofyourfirstdnsserver.com. nameofyourseconddnsserver.com. (

1000000; Serial

10800 ; Refresh - 3 hours

3600 ; Retry - 1 hour

86400 ; Expire - 24 hours

3600 ) ; Minimum - 1 hour

IN NS nameofyourfirstdnsserver.com
www IN A ipaddressofwebserver ftp

IN A ipaddressofftpserver smtp

IN A ipaddressofmailserver
This should be saved in the directory specified in the first few lines of /etc/named.conf. Now, we will configure a secondary DNS server, or a slave DNS server. This is much easier than setting up the primary/master server. The only file to change will be the /etc/named.conf on the secondary server. You should save the following in the /etc/named.conf file:

zone "desireddomain.com" { type slave; file "desireddomain.db"; };

Now, we can grab the configuration file from the first server using a utility that comes with BIND, named-xfer. We will do this by entering:

named-xfer -z desireddomain.com -f desireddomain.db \ -s 0 addressofprimarynameserver

This will copy the configuration file from the primary DNS server. BIND should start automatically, if not, you may start it with the following command (for most systems):
/etc/init.d/named start

You should allow somewhere between 24 and 48 hours for the DNS records to be updated once you move your DNS server from host to host. DNS is a great protocol, and makes our lives easier, by allowing us to be lazy (simply type a domain name instead of an IP).

Naming of Windows Workgroups and Domains

Each Windows computer belongs either to a workgroup or a domain. Home networks and other small LANs utilize workgroups, whereas larger business networks operate with domains. Choosing proper workgroup and/or domain names is essential to avoiding technical problems in networking Windows computers. Ensure your workgroups and/or domains are named appropriately according to the following rules;

• Ensure each workgroup and domain name is no longer than 15 characters.


• Ensure no workgroup or domain name contains spaces. Windows ME and earlier versions of Windows do not support workgroups or domains with spaces in their name.


• Whenever possible, ensure all computers on the LAN use the same workgroup/domain name. Using common workgroups/domains makes it easier to browse the network and avoids some security complications when sharing files. Note that the default workgroup name in Windows XP is "MSHOME" but in older versions of Windows is "WORKGROUP".


• Ensure the name of the workgroup/domain is different from the name of any computer on that network.

Avoid special characters in workgroup and domain names. Whenever possible, do not use any of the characters when naming Windows workgroups and domains: / \ * , . " @

• For simplicity, avoid using lower-case letters in workgroup or domain names.


• The workgroup name need not match the network name (SSID) on a Wi-Fi LAN.

To set or change workgroup/domain names in Windows XP, right-click on My Computer or open the System icon in Control Panel, then choose the Computer Name tab and finally, click the Change... button to access the workgroup/domain name fields.

To set or change workgroup/domain names in Windows 2000, open the System icon in Control Panel and choose the Network Identification tab, then click the Properties button.

To set or change workgroup/domain names in older versions of Windows, open the Network icon in Control Panel and choose the Identification tab.
