configure Windows Server 2003 DNS server

How do I install and configure Windows Server 2003 DNS server?

The Domain Name System (DNS) is the Active Directory locator in Windows 2000 and Windows Server 2003. Active Directory clients and client tools use DNS to locate domain controllers for administration and logon. You must have a DNS server installed and configured for Active Directory and the associated client software to function correctly. This article guides you through the required DNS configuration.

Install Microsoft DNS Server

1. Click Start, point to Settings, and then click Control Panel.
2. Double-click Add/Remove Programs.
3. Click Add and Remove Windows Components.
4. The Windows Components Wizard starts. Click Next.
5. Click Networking Services, and then click Details.
6. Click to select the Domain Name System (DNS) check box, and then click OK.
7. Click OK to start server Setup. The DNS server and tool files are copied to your computer.
8. Continue to the next step to configure the DNS server.

Configure the DNS Server Using DNS Manager

These steps guide you through configuring DNS by using the DNS Manager snap-in in Microsoft Management Console (MMC).

1. Click Start, point to Programs, point to Administrative Tools, and then click DNS Manager. You see two zones under your computer name: Forward Lookup Zone and Reverse Lookup Zone.
2. The DNS Server Configuration Wizard starts. Click Next.
3. If the Wizard does not auto-start, right-click your server name object in the DNS Manager console and choose Configure your Server.

4. Choose to add a forward lookup zone. Click Next. The new forward lookup zone must be a primary zone so that it can accept dynamic updates. Click Primary, and then click Next.

5. The zone name must be exactly the same as your Active Directory Domain name, or, if on a stand-alone or workgroup environment - the same as the suffix for all of the network computers that are to register with this DNS server. Type the name of the zone, and then click Next.

6. Accept the default name for the new zone file. Click Next.

7. Choose to add a reverse lookup zone now. Click Next.

8. Click Primary, and then click Next.
9. Type the name of the zone, and then click Next. The zone name should match the Network ID of your local subnet. For example, if your subnet range is from 192.168.0.1 to 192.168.0.254, type 192.168.0 in the name value.

10. Accept the default name for the new zone file. Click Next.

11. Click Finish to complete the Server Configuration Wizard.

After the Server Configuration Wizard is finished, DNS Manager starts. Proceed to the next step to enable dynamic update on the zone you just added.

Enable Dynamic Update on the Forward and Reverse Lookup Zones (Optional - Recommended)

1. In DNS Manager, expand the DNS Server object.
2. Expand the Forward Lookup Zones folder.
3. Right-click the zone you created, and then click Properties.
4. On the General tab, click to select the Allow Dynamic Update check box, and then click OK to accept the change.

5. Do the same for the Reverse Lookup Zone.

Enable DNS Forwarding for Internet connections

1. Click Start, point to Programs, point to Administrative Tools, and then click DNS to start the DNS Management Console.
2. Right click the DNS Server object for your server in the left pane of the console, and click Properties.

3. Click the Forwarders tab.
4. Check the Enable forwarders check-box.
5. In the IP address box enter the IP address of the DNS servers you want to forward queries to - typically the DNS server of your ISP. You can also move them up or down. The one that is highest in the list gets the first try, and if it does not respond within a given time limit - the query will be forwarded to the next server in the list.

6. Click OK.

svn configration for windows

Installing Subversion

- Double-click on the installer and run through it. Shouldn't take too long. Once installed, add an environment variable for SVN_EDITOR. You can do this by right-click on my Computer > Properties. Go to advanced. Hit the Environmental Variables button. Just add another in there called SVN_EDITOR with a value of C:\windows\notepad.exe

Creating a Repository

- Now you need to create a repository. Go to the command prompt (Start > run > cmd). type "svnadmin create D:\Programming\MySVNRepos". (Change the path to whatever path you want to use.) The repos is basically a special directory that will hold your files as well as various subversion config options.

Modifying Security and Authentication Settings

- Next up, you need to modify the permissions and u

sers. Navigate to the folder you just created. In my example, I used D:\Programming\MySVNRepos". In this directory, you will find a few folders. One folder will be called conf. Navigate to it and double-click on the svnserv.conf file. Opening it with notepad will be fine.

- The svnserv.conf file in a configuration file for the svnserv executible. For our purposes, just uncomment out the following lines:

[general]

anon-access = read

auth-access = write

password-db = passwd

- Save your changes. And double-click on the passwd file in the same directory. The file stores all usernames and passwords in the format:

$username = $password

- Make sure the [Users] line is uncommented and you can just add a new line for your username and password. For example, if you wanted your username to be josh and your password to be testing, just create a line like this:

josh = testing

- Save it and you're done configuring.

Serving Your Repos for the First Time

Now, you can test it out. Go to the command prompt again and type:

svnserve --daemon --root "D:\Programming\MySVNRepos"

Change the path to your specified path. Once this is done, the daemon should be listening and waiting for requests.

Creating your First Project folder

Click on startà runà and type following url

svn://localhost it will opne the following window.

Then right click on svn://localhost add a new folder as shown below .

Subversion will ask for your username and password.

However, keep in mind, it may also ask for your computer's Admin password. If it does, you can simply type in your computer's admin password. Once you hit return, you can then go ahead and type in your subversion username and then your subversion password. Your subversion username and password is exactly what you typed in the passwd file. (i.e. user: josh pass:testing)

Then create a project folder (I created test folder) on C, D or any drive. Right click on that project folder and do the svn checkout as per following.

Give the svn repository path as per the following..

After finishing the checkout click on ok.

Then copy the folder actual project folder into new project folder in my case it is test folder and I copied modernfamily actual project folder under test test folder.

After finishing the coping right click on modernfamily (your might be dfferent project folder) folder and add the files as show below.

After clicking on add tag it will appear the following window just click on ok tab as shown below.

Wait till adding thefiles and click on OK tab as per below…

After finishing the file adding then come to the root folder that is test folder right click on it and do the coming as shown below…

It will appear following window jist click on OK tab.

After finishing the commit again click on Ok tab that window is not shown here.

Running svnserv as a Windows Service

If you're running XP (Win2k, Win2k3, or Vista), you can tell the process to run as a service. Stop your existing svnserv daemon by closing out of the existing command prompt window. Now, go to the command prompt (again). Type:

sc create svnrepos binpath= "\"C:\program files\subversion\bin\svnserve.exe\" --service --root \"D:\Programming\MySVNRepos" displayname= "Subversion Repository" depend= Tcpip start= auto

(Note: add your repo path in command)

After adding service go to the services an check Subversion repository service is added. If it is added then start the service.

SVN Checkout on client system.

Make new folder and give your project folder name. Right click on same folder and click on svn checkout and give your repository path.

svnadmin hotcopy path/to/repository path/to/backup --clean-logs

Svnadmin dump reponame > reponame.dump For backup

Svnadmin load newrepo < style=""> For restore dump file
