No Asp.net 2.0 in IIS Web Service Extension

The ASP. NET V2.0 component is installed on the server, but ASP. Net v2.050727 is not found in the Web service extension of IIS. As a result, the web pages developed based on. net2.0 cannot be browsed normally.

Solution:
Open IIS, go to Web service extensions, click "Add a new Web Service extension" under the window task on the right. In the displayed window, click Add and find X: \ windows \ Microsoft. net \ framework \ v2.0.50727 \ aspnet_isapi.dll (X is the system installation drive letter, and a disk is C), click OK to save the settings, and then set its status to "allowed.

Possible problems:
When the webpage is opened, an error is prompted: The current identity (nt authority \ Network Service) is not correct.The write access permission for "C: \ WINDOWS \ Microsoft. NET \ framework \ v2.0.50727 \ temporary ASP. NET files" is incorrect.
In cmd mode, enter c: \ windows \ Microsoft. net \ framework \ v2.0.50727 \ aspnet_regiis-I-enable (same as above, C is the system installation drive letter). After installation, the system will return to normal.
