Try the following method:

Analysis:
The user's anonymous access account (IUSR _ machine name by default) is disabled or has no permission to access the computer.
Solution: (1) check whether the anonymous account set for site security in IIS manager is disabled. If yes, try the following methods to enable it:
Control Panel-> Administrative Tools-> Computer Management-> local users and groups, enable IUSR _ machine name account. If the problem persists, proceed to the next step.
(2) check whether the default anonymous access account of the site in the IIS manager or its group has the permission to access the server over the network in the Local Security Policy, if you have not attempted to grant permissions by following these steps:
Start-> Program-> Administrative Tools-> Local Security Policy-> local policy-> User permission assignment, double-click "Access this computer from network ", add default IIS users or their groups. Note: Generally, custom IIS default anonymous access accounts belong to groups. To ensure security, follow this rule.
