Network Solution for Windows – Windows system, Linux system, Ubuntu server configuration tip

In this article we will learn about services DFS – Distributed File System and how to develop a system DFS on Windows Server 2003. …
1. About DFS

DFS is used to build the structure assigned to represent many locations to share data on many different file server. If your network has multiple file server, each file server has a shared folder contains data, you will have problems when they do remember to share on any server. DFS but instead must share the memory associated with each file server, you will only have to remember a unique name to go to all shared on all servers. You can imagine what that name as a “home” of all shared files, the “home” that contains a link pointing to the actual location of the shared folders on the file server. DFS client can lead to the most recent server File can using “Active Directory site metric. DFS can also set on a Cluster System to provide better performance and reliability higher.

DFS to work out as yet, we need to understand some terms:
DFS Root is a root name for the DFS link. You can understand it as a “Root Share”, which you may have files and other directories.
DFS Link: path to a shared folder is located in a specific network. When user access to DFS Link will be redirected to the actual share.
DFS Target (Replica): can be DFS or DFS Root Link. If you have 2 share exactly the same but stored in 2 different location, you can group them in a DFS target.

Directory structure of a real system DFS

Windows Server 2003 was upgraded services Distributed File System from Windows Server 2000, it provides better performance, ability against error (fault tolerance), load balancing and reduce bandwidth use. It comes with a series of command line tools to help back up and restore DFS name space –

DFS Namespace easier.

To understand more easily, we consider the following situations:

System of DaiVyCorp INC the server name is: dc01, server01-File, File-server02, server03-File, in which:

- File-server01: shared folder setup, Resource, User access via path: \ \ File-server01 \ Setup and \ \ File-server01 \ Resource

- File-server02: shared folders Student, Examination, access through the link: \ \ File-server02 \Student and \ \ File-server02 \ Examination

- File-server03: shared folders Music, Picture, access through the link: \ \ File-server03 \ Music and \ \ File-server03 \ Picture

We use the server as a DFS Root dc01 (stand-alone form, such), the DFS Root called Data, users can all share in the path: \ \ dc01 \ Data \ Setup \ \ dc01 \ Data \ Resource; dc01 \ Data \ Hocvien; dc01 \ Data \ Music … without which the share on any server!

2. Install and configure DFS

Tools to manipulate DFS is Distributed File System console pre-installed in Windows Server 2003, your Start menu> All Programs> Administrative Tools> Distributed File System to open the tool.

- First, your My Computer, on a drive that, create a folder to contain DFS Root. Here I select drive E, create a folder named Data to contain DFS Root.

- The first step, you must create a DFS Root. You must click the Distributed File System select New Root. Root is the highest level in the structure of DFS. Unlike Windows Server 2000, Windows Server 2003 allows you to have more than one root.

- Click next page Wellcome ignored the first, you go to Root Type page, where you choose one of two types root is root Domain and Stand – alone root. Domain root will save the entire configuration in the DFS Active Directory, supports automatic file synchronization and error-resistant, while stand-alone root is not. If you have a domain, I recommend that you select Domain root.

If you select Domain root, users will access using the path: \ \ domain-name \ DFSRoot-name \ …

If you choose Stand-alone root, users will access using the path: \ \ server-name \ DFSRoot-name \ …

Here I choose to root Domain.

- At the next page Host domain, select your domain that you want to contain DFS Root. If you only have one domain in the Domain Host has only one domain appear. You enter the correct name of your domain then click Next.

- Next, in Host server, you enter the FQDN of the server name containing the DFS Root.

- Next, you enter the Root Name. You note that domain name and Root name will change the path that users access the share, so you should set the Root name short, the meaning clear.

- At the next page, Root share, you enter or Browse to the folder containing the DFS Root. For security reasons, you should contain a folder in a drive other drive system.

- Click Finish finish creating DFS root. Then you will see DFS Root you’ve created appear. You must click on the DFS Root and select Check Status to check the status of Status. If status is online, and you see a green check mark beside the name of the DFS Root means it is working well.

- The next link you must create a folder to share. You must click on the correct DFS Root you want and select New Link (you choose the right note DFS Root, because in Windows Server 2003 can generate more than one DFS root).

- New Link Page will next create a link from a DFS Root folder to share on the actual network. You fill in the necessary parameters such as Link Name (the name of Link), Path to target (the path to shared folder on the actual network), Comments (comments) …

Similarly, you need to point to how much shared folder on the server do you create this much link corresponding to them.

- From the client, you will have access to the shared folder with a common path, such as your case is: \ \ domainname \ data
