ASP tip: Access to IIS virtual directories requires a resolution of permissions

iis| Access | tips | solutions | virtual directory

A 403 permission error is caused by an incorrect IIS or disk permission configuration.

The following is the solution to the idea.

1. The hard disk is in NTFS format, modify the site root folder properties, add IUSR_ to your machine name and IWAM_ your machine name in the security options, or put the file under Wwwroot and select Inherit permissions from the parent folder.

2. Under the authority of the site, you can also specify the permissions for each file or directory under the site. (If your site is anonymous, but the next file is designated as not anonymous access, the same password)

3. In the site root directory, right → attributes → security → add everyone user, and at least Read permissions.

4. Set the Directory Security tab in the Site properties and click the Edit button next to anonymous access and validation control to remove the integrated Windows validation.

5. Do not ignore the link to the picture. Under Anonymous access, it can also cause a validation dialog box to appear, and each picture appears once (if an absolute URL is used)

6. If you installed the FrontPage Server Extensions when you installed IIS, uninstall them if they are installed.
