In asp.net, the component "Access Denied" is displayed.

Sometimes, when we debug the ASP.net program, it will be very painful. Access to a certain component is denied. At this time, Restarting IIS does not work when the computer logs out. At this time, the error message is generally similar to the following method:

"/" Indicates a server error in the application.

The most common cause is the Indexing service. The solution is to disable the Indexing service, or configure the temporary directory of ASP.net not to be affected by the Indexing service.

To configure the temporary directory of ASP.net not affected by the Indexing service, follow these steps:

1. Start-management tools-Computer Management (similar to other operating systems in Win2003)
2. Expand the "service and application" node in the left-side tree of Computer Management, then expand the "Index Service" node under it, and then expand the "System" node under it, expand the "directory" node under it.
3. On the right of Computer Management, we can see the configured index service directory.
4. Right-click the "directory" node and choose "New"> "directory"
5. In the "add directory" dialog box, enter the temporary file directory of ASP.net in the input box. The default value is:
C: \ <WINDIR> \ Microsoft. NET \ Framework \ <Version Number> \ Temporary ASP. NET Files directory.
<Version Number> indicates the. net Version to be processed.
6. Is it included in the index ?" Select "no"
7. Click OK.
8. Right-click the "Index Service" node and restart the Index Service.
