Summary of differences between the number of concurrent connections per server and each device or user in server authorization Mode

Server authorization mode: differences between the number of concurrent connections per server and each device or user
Authentication per server: the number of concurrent client users allowed to access the service at the same time;
Each customer authentication: indicates that each of your clients has an authentication license, through which the client accesses the server;
Example:
The company has two servers: Server1 and Server2;
Client: 100;
If you choose to authenticate each server, you need to select 100 for each of Server1 and Server2, a total of 200 certifications, in order to meet the needs of simultaneous access by 100 clients;
If you select customer authentication, you only need 100 customer authentication to meet the access needs of 100 clients;

You can select different authentication methods based on your needs.
Change local server to per device or per user authorization
1. Open "select authorization mode" on the server to be configured ".
2. In "product", click the product to change the authorization mode.
3. Click "per device or user ".
To open a control panel project, click Start, click control panel, and then double-click authorize ".

Web Server Permissions

You can configure the following permissions for IIS to specify the Web site directory, such as read and directory browsing permissions. It is important to understand the differences between Web Server permissions and NTFS permissions. Unlike NTFS, the Web server Permission applies to all users who access the Web and FTP sites. NTFS permission applies only to specific users or user groups with valid Windows accounts. NTFS controls access to physical directories on the server, while Web and FTP permissions control access to virtual directories on the Web or FTP site.
If you select "per device or user" mode, each device or user accessing the Server running the Windows Server 2003 Family product must have a separate "Client Access License (CAL )". With a CAL, a specific device or user can connect to any number of servers running Windows Server 2003 Family products. Most companies that have multiple servers running the Windows Server 2003 Family products use this authorization method.
On the contrary, each server license means that each concurrent connection to this server requires a separate CAL. In other words, this server can support a fixed number of connections at any time. For example, if you select the "per server" client Authorization mode with five licenses, the server can have five concurrent connections at a time (if each client needs a connection, five clients are allowed at a time ). Clients using these connections do not require any other licenses.
The authorization mode per server is often the first choice for small companies with only one server. This authorization mode is also useful for Internet or remote Server access when the client computer may not be authorized as a network client of the Windows Server 2003 Family product. You can specify the maximum number of concurrent server connections and reject any additional login requests.
If you are not sure which mode to use, select "per server" because you can change from "per server" mode to "per device" or "per user" mode, without any cost.
Differences between each server and each client)
Understand the differences between each server and each client during window2003 Installation
　　
During the installation of WIN2003, the textbooks mentioned whether to choose "per server" or "per client". The explanations in the textbooks were not clear, and the students were even more confused in class. Today, I just called Microsoft 8008203800 and finally figured it out.
　　
To install and use a WIN2003 system, you must pay two yuan: WIN2003 software and user license. WIN2003 officially quoted more than 30 thousand yuan, with each user license of 340 yuan. The following uses a company as an example.
　　
A company has 50 computers connected to a LAN, and another server is installed with the WIN2003 system, company users can access no more than 30 servers at the same time (including shared files or printers through network neighbors). The cost is: 1 set of WIN2003 price 30 thousand, 30 user license price 340X30. Select the mode for each server when installing WIN2003, and enter 30 for the number of users.
　　
If the company needs to install another WIN2003 system in a short time, and there are also 30 users accessing the server, the company will have to spend more than 30 thousand RMB.
　　
In the above cases, the company has only 50 computers. However, since they access two servers at the same time, each server has a maximum of 30 visitors. Therefore, it is quite expensive to use the above methods for each server, A better solution is to replace WIN2003 in the company with the customer model. In this way, the company needs to spend a total of 30 thousand x 2 sets + x 50 sets. In the future, if the company adds another WIN2003 server, it only needs a set of WIN2003 money, you no longer need to add a license to the customer, unless you have added a new user computer in the company.
　　
　　
Note the following points:
　　
1. In the above example, the client computer is not genuine and has nothing to do with the user license purchased for WIN2003, that is, even if the client computer is already a genuine XP user, if you want to use the network service provided by WIN2003, you must purchase a user license.
　　
2. WIN2003 purchased in June 30 thousand is only the price of the software. If you need to access WIN2003 shared files and Shared printing, you must purchase a user license.
　　
3. If WIN2003 does not provide services such as user sharing, but is used by a WEB server, you have to purchase a WEB access license in addition to spending 30 thousand Yuan to purchase WIN2003, the WEB access permission has nothing to do with the number of users simultaneously accessing the website. The price for a WEB Access License is more than 20 thousand.
　　
4. the user license paid by the company is not a specific program or software, but a license contract issued by Microsoft, indicating that your company is legally using the software, otherwise, it is called the dversion.
