Using Windows 2003 Deployment Software

As a network administrator, one of the most common tasks is the deployment of various software, including system software and application software. In a large-scale network environment, deploying software by means of installation disks for local installation is inefficient, affects work, and may cause errors. Therefore, the common installation method in this case is network installation. However, the current network installation generally uses a shared installation disk for installation. This installation method has two main disadvantages: First, the client must be connected to the server, otherwise the shared resources cannot be accessed. For example, a new machine without any system cannot. The use of shared resources; Second, even after the client connected to the server's share, in the process of installing the application, there must still be an administrator to participate in the presence of the application, otherwise some installation options can not be determined, the installation process can not continue. Therefore, administrators must master some effective methods to efficiently complete the work of the daily software department.

In order to solve the problem of deployment in the software network, Windows Server 2003 provides two technologies, RIS and Installer. The former is a remote installation service, which provides remote installation of the operating system for clients in the network through Windows Server. The latter is specifically designed to address the need to publish applications in a Windows network environment. In addition, Windows Server 2003 provides the ability to quickly deploy changes.

Remote Installation Services

Remote Installation Services (RIS) is a built-in network service for Windows Server 2003. This method enables clients to pass the "Guide Information Negotiation Protocol" (BINL) in a domain environment. ") access the server and request the server to provide the operating system, and the server can use the "Simple File Transfer Protocol (TFTP)" to download the required installation files for the client after responding to the request. At the same time, the RIS server adopts the “single instance storage (SIS)” technology, which can ensure that when processing a large number of client installation requests, it not only occupies system resources, thus providing system guarantee for software deployment in a large network. The specific process is described below.

1. Configuring the RIS Server

As with other Windows services, the installation of the RIS service can be done through the "Windows Components Wizard", which requires the Windows Server 2003 system installation CD.

2. Specifying User Rights

In a security system such as Windows Server 2003, the completion of any work is subject to resource permissions and user rights, so which users should be defined after installing the RIS service. This service can be used on the client to install the operating system, which requires the power of the specified user. There are two main powers: one is the power to add computers to the network; the other is the ability to process installation tasks in batches. As shown in Figure 1, these two rights are assigned to the user in the domain controller's "Active Directory Users and Computers".

(1) Specify the power to add a computer

First, in the "Active Directory Users and Computers" manager, right-click the domain or organizational unit where you want to install the client. As shown in Figure 2, select “Delegation Control (E)…” in the pop-up menu. Then in the "Delegation Control Wizard", specify the users who are authorized to install the client, and assign them the power to add computers to the domain, as shown in Figure 2, follow the wizard's prompts to complete the operation.

(2) Specify the power to batch process installation tasks

After assigning the user's power to add computers, go back to the "Active Directory Users and Computers" manager and continue to define the batch processing installation tasks. Power. Once again, right click on the desired domain or organizational unit as shown in Figure 1. Select “Properties(R)” in the Properties window of Figure 3, select Edit Group Policy.

When editing Group Policy, the system will open the “Group Policy Editor”. In the location shown in Figure 4, double-click “Log in as a batch job” to specify network users and define policy settings. . You can add a user or group (U)…” button to the <; and then follow the prompts to add the user who will be installing the system on the client to this policy.

3. Preparing the Installer

Before installing the operating system on the client, you must first prepare the installer for its system on the RIS server so that the client can automatically obtain the required source files from the server at the time of installation. This is done by the Risetup.exe server configuration wizard provided by the RIS server, which copies the required source files to the server and can be transferred over the network when the client is installed. Running the Risetup.exe program starts the "Remote Installation Service Installer Wizard". Then proceed to the next operation.

(1) set the client installation location; (2) specify the response to the client; (3) define the location of the source file to be copied this time; (4) specify the folder name; (5) ) Installation instructions.
