cannot verify access to pass ...wwwroot\wss... error

I am getting an error after Test Settings that says "The server is configured to use pass-through authentication with a built-in account to access the specified physical path. However, IIS Manager cannot verify whether the built-in account has access. Make sure that the application pool identity has Read access to the physical path. If this server is joined to a domain, and the application pool identity is NetworkService or LocalSystem, verify that <domain>\<computer_name>$ has Read access to the physical path. Then test these settings again."

Can anyone tell me how to solve this issue? Thanks for any information.

You will need to ensure the computer name Server$ has permissions on the remote path. If a computer is added to an active directory domain, then its account is named MachineName$, with a dollar sign at the end of it. You will then be able to use Windows Explorer to grant Share and Ntfs permissions on your physical folder. When the network services gets access to a remote resource, then it will use the machine account as the actual account.

Download a tool called Process Monitor, from the below link, which is an advanced monitoring tool for Windows that shows real-time file system, Registry and process/thread activity. It combines the features of two legacy Sysinternals utilities, Filemon and Regmon, and adds an extensive list of enhancements including rich and non-destructive filtering, comprehensive event properties such session IDs and user names, reliable process information, full thread stacks with integrated symbol support for each operation, simultaneous logging to a file, and much more.
