Server Application Unavailable causes and solutions

The error message is as follows:
Copy codeThe Code is as follows:
Server Application Unavailable
The web application you are attempting to access on this web server is currently unavailable. Please hit the "Refresh" button in your web browser to retry your request.

This problem is generally caused by the following reasons:
1. Users in the users group have no read and write permissions on site files. Solution: Set the Users Group read and write permissions for the site directory.
2. The site Asp.net version is incorrect. This problem may occur when multiple versions of the FrameWork coexist, such as Asp. net1.1 and 2.0. Solution: site-> properties-select the current Asp.net version.
3. Application pool conflict solution: Create an application pool in application pool-> Create an application pool, and then select the application pool you just created in the home directory of Site-> properties->.
Note: The above three reasons may occur at the same time and can be solved gradually. Supplement: Sometimes "Service Unavailable" may occur. This is a common error in IIS7. The general cause is: at the same time, online users or bandwidth exceeds the limit, and the corresponding site address pool is stopped (for many reasons ).

Independent Application pool for Asp. net1.1 and 2.0 Problems

The "Server Application Unavailable" prompt appears when the. net page file is browsed. It usually appears on the machine where. net Framework1.1 (or 1.0) and. net Framework2.0 coexist.

The cause of this error is. net Framework 2.0 programs and. net Framework1.1 (or 1.0) programs are placed in the same Application pool. If you click "mutual access" on the program page, "Server Application Unavailable (Server Application Unavailable)" appears).

To solve this problem, create two program pools in IIS, one for storing the. net Framework1.1 program directory and the other for storing the. net Framework2.0 program directory.

However, I encountered the following situation: although the machine is running at the same time. net Framework1.1 and. net Framework2.0, but not on the machine. net Framework1.1 program file, so the. net Framework1.1 program file has been stored in IIS. net Framework1.1 web service extensions are disabled. A program pool dedicated to. net Framework2.0 is also created. The problem persists.

I found a one-to-one comparison from the online search, rarely similar to me. However, I finally found some reference prompts, which may be a permission issue. In addition to the superuser control permission and IIS process, no other users can access the folder. Therefore, an "User" Access Group is added and the problem is solved immediately.

I have solved the problem. Extract an article for backup.

Some other solutions are provided:
1. Change User attributes in Machine. config to the SYSTEM group.
2. Grant all request permissions to the account ASPNET:
1) Open "Resource Manager" and change the directory to "\ Documents and Settings"
2) If the "LocalService" directory is invisible, select "Tools"-"Folder Options ", then, make sure that the "Hide System Files" tab is not selected.
3) continue to "\ Documents and Settings \ LocalService"
4) Right-click the "LocalService" folder and select "share and security"
5) on the Security tab, add the "ASPNET" user to ensure that it has the "read" and "list" permissions.
6) Click "application" ("OK") until all windows are closed.

Solutions to Server Application Unavailable

I haven't tested other system programs for a long time today. I am very interested today. I saw a website building system on the Internet. The problem is that the website building system is. if you want to see it, your system must be installed with asp.net. Currently, the system I use is windows xp, not windows or not, it seems that the installation is indeed a little effort, first the local installation of asp. net2.0, and the local machine already has iis, so you should specify the directory for access first, but a prompt appears during access

Administrator Note: An error message detailing the cause of this specific request failure can be found in the application event log of the web server. please review this log entry to discover what caused this error to occur.

This problem seems to have been encountered during previous tests. It seems that asp. net1.0 is still used. I forgot about it. I found a lot of relevant solutions on the Internet, but I still did not solve the problem. When I found this solution very blindly, I succeeded in testing it!

Register ASP. NET in IIS

Open my computer, enter the system disk (assuming drive C), and enter the path C: \ WINDOWS \ Microsoft. NET \ Framework \, here, you will see the different versions you have installed.. NET Framework Directory, which is assumed to be used by your website. if the NET version is 2.0, go to the v2.0.50727 directory (full path: C: \ WINDOWS \ Microsoft. NET \ Framework \ v2.0.50727 ).

In this directory, you can see a file named aspnet_regiis.exe, which is a command line execution file.

Click "Start/run", enter "cmd" in "open", and press enter to open the Command run window and change the current path to C: \ WINDOWS \ Microsoft. NET \ Framework \ v2.0.50727, enter aspnet_regiis.exe-I and press Enter.

After performing the preceding operations, Test Access to the installation directory file from the address bar and find that the installation directory file is accessible. The problem is solved! I hope the above operations will help you to see this article. If you cannot solve your problem, try other solutions!
