I am having issues with an WSUS configuration. When I go into IIS 7 Manager -> Basic settings -> and attempt to test the connection I get the following error:
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.
I verified that NetworkService has the appropriate Read access on the folder in question.
