Technical Information (for support personnel)
Background:
The cause of this error is that the Web server is busy and cannot process your request because of heavy traffic.
Details:
Microsoft support

1. Both windows2000pro and WindowsXP allow only the number of online users with 10 connections at the same time. If the object is not released in time, even if you access it by yourself, too many users will be prompted.

2. There are 10. If you press F5 to refresh the page multiple times during the test, it will not take long for you to prompt that there are too many visitors.

3. I have encountered this problem, yesProgramAfter opening the database, you must ensure that conn. Close is required. Check your program well. There must be a place where the database is always on.

4. If the number of IIS connections is too large, you can increase the number of IIS connections. If you do not want to limit the number of IIS connections, set it to 2003 Server or.

6. If you do not want to reinstall the system, use Apache for webserver.

5. We recommend that you change the 2kserver system or release all the objects created with server. Create at the end of the page in a timely manner during programming, but this will reduce the response speed of user access,

7. If the VM is used, the traffic that the Network Space Provider sets for you is too small. Ask your network space provider to increase the traffic limit. (May be charged)

8. Now we can find a good software to lift the IIS connection limit. We can use ntswitch software.
If your operating system is Windows/XP Professional, first install IIS, run ntswitch software, click the "goserver" button, the software will pop up a confirmation box for you to switch the operating system, click OK, restart the machine and you will find that the operating system startup logo image has changed from the original professional logo to the server logo. (Note: The server system can be converted to a professional system by clicking the goworkstation button)
In this step, if you open IIS and modify the number of IIS connections, you will find that the number of IIS Connections cannot be modified at all. Does this software work? When you restart the machine, you may have noticed that after the machine is started, an error message is displayed, "at least one service or driver has an error. For details, please use the Event Viewer to view Event Logs. "after you open the system log to view several error logs, you will find that the WWW, SMTP, and FTP services are stopped unexpectedly. The reason for stopping is: the system cannot find the specified file.
The final solution is to uninstall the IIS on your local machine and install it again. Start the machine again and all problems will be solved, when you enable IIS again, you will find that you already have a brand new sever system, IIS, and how to change the number of connections. Ntswitch software can be downloaded from the Internet,

9. Generally, You can restart IIS to solve this problem by entering iisreset in "run ".

10. microsoft provides metaedit, a tool for managing IIS. metaedit works on windowsnt4.0 and Windows2000. I found that metaedit works normally on WindowsXP. In addition, metaedit can only manage IIS of version ii4.0, iis5.0, or later.
The following uses this tool to break through the connection restrictions of the IIS client of Windows XP Professional Edition:
First, you need to download metaedit from the following address. The latest version is 2.2.
(For WINXP + SP2, download the latest version 2.11a of the SP2 limit connections patch and view the description at the end of this article)
Then, execute mtaedt22.exe and follow the wizard prompts to complete metaedit installation.
Finally, set the client connection limit parameter in metaedit.
After metaedit is installed, click metaedit2.2 under the "administrativetools" program group in the Start Menu. A window is displayed:
Expand the tree to Lm \ W3SVC on the left side of the window, click the w3svc folder, and select the maxconnections item in the list on the right. After double-clicking, a dialog box is displayed:
In the last data text box, the default value is 10, which is Windows XP Professional IIS.
The maximum number of client connections set by default. Now you can change this default value. I will change it to 10000,
Note: The maximum number of IIS client connections on win2000 is 2000000000.

11. The following is a solution:
Of course, the number of connections is not the number of IP addresses. It is the connection requested by the browser. You may think that the response is stopped if the upper limit is not reached. This is because when the browser requests a connection, data transmission is interrupted (this can be caused by network faults, browser crashes, users click the stop button of the browser, and so on). At this time, the opened connection will occupy server resources until the connection times out and closes. When the browser does not communicate for a period of time, the connection will be closed automatically upon arrival. You can see that the "connection time limit" in the attribute is 900 seconds by default. Appropriately shorten the time limit to effectively release unused connections. Also, "enable and maintain HTTP activation" is used to maintain the current browser connection, in order to respond to browser requests more quickly. It also consumes resources.

I have not studied it in depth. There are still many things to explore. Let's leave it for you to study. Do not forget to tell me any new discoveries.

In addition, I tried to install IIS of other versions such as IIS6 and iis5 of win2000server on XP by modifying the installation information of Windows Components, but all of them ended in failure. IIS cannot run after it is installed! In addition, no successful cases have been found on the Internet. Most of them say that IIS6 can only run on Windows 2003.

The so-called bare metal here refers to a computer without any operating system, but the premise is that the normal hardware can enter the CMOS settings. First, you need to partition and format the hard disk using some tools. Below, Fei Long will talk about several cainiao-level countermeasures in the sky, hoping to be helpful to cainiao.

Countermeasure 1: When an optical drive is available,
1. Use winpe to install the CD. First install winpe on the hard disk (that is, winpe on the hard disk ).
2. Copy the deepin Lite version to a non-system partition of the hard disk, such as an edisk.
3. Restart winpe on the hard disk, find the deepin installation file, and double-click winnt32.bat to wait for the installation to stop.
4. Restart your computer and wait until the installation is complete.

Countermeasure 2: If an optical drive is available,
1. Use the deepin Lite version to install the CD directly. Find the deepin Installation File and double-click winnt32.bat to wait for the installation to stop.
2. Restart your computer and wait until the installation is complete.

Countermeasure 3: USB flash drives
1. Create a USB flash drive that can start winpe (I don't like it too hard ). Start the USB flash drive winpe.
2. Copy the deepin Lite version to a non-system partition of the hard disk, such as an edisk.
3. Find the deepin Installation File and double-click winnt32.bat to wait for the installation to stop.
4. Restart your computer and wait until the installation is complete.

countermeasure 4: remove the hard disk of the computer without a USB flash drive.
1.
2. Try to connect to the IDE interface and interface power of another computer.
3. Install winpe on a desktop computer. Copy the deepin installation file to a non-system partition, such as an edisk.
4. Remove the hard disk and install it back to the original computer.
5. log on to the hard disk version of winpe, find the deepin installation file, and double-click winnt32.bat to wait for the installation to stop.
6. Restart your computer and wait until the installation is complete.
