ASP. NET solves the problem of "server application unavailable" when using IIS to set up a website. asp. netiis

The server application is unavailable. The Web application you are attempting to access on this Web server is currently unavailable. Please click "refresh" in the Web browser to try your request again. Administrator Note: error messages that detail the cause of the specific request failure can be found in the system event log of the Web server. Check this log item to find out the cause of this error.

This is probably because IIS installed after. Net Framework is installed, and. Net is not registered in IIS.

I have been searching for it online for a long time. run aspnet_regIIS/I in the. net command line tool (or in a directory similar to the following: C: \ WINDOWS \ Microsoft. NET \ Framework \ v1.1.4322 \ aspnet_regiis.exe-I), but I tried many times, but later I found that I had to uninstall, install, and recreate the application as follows:

Run aspnet_regIIS/u In the. net command line tool to uninstall it, And then install aspnet_regIIS/I.

Restart IIS, delete the "Default Application", and recreate the site as an application.

In addition, it may be that the ASPNET account does not have the permission for the server directory specified by IIS. In resource manager, find "tools-Folder Options-View-use simple folder sharing (recommended)", remove the preceding check box, and right-click the directory specified on the server, property-security-add-advanced-search now, add the account ASPNET, and grant it full access permissions. After doing so, you will find that the error does not exist. However, if you access the database, you may be prompted that the account ASPNET has no permission to access the database. This prompt is much clearer. You can add the corresponding permissions to the account in the database.
