If you don't specify user credential in the UNC path setting, then you want
pass-through authentication, which either use the authenticated users of the
app, either an authenticated user (in basic or other auth) or iusr for the
case of anonymous access. since these identities doens't have valid account
in the remote resource, ACL checking will failed and you got - 500.16
500.16 ¨C UNC authorization credentials incorrect.
so pass-through is good if you want to authenticated user to access remote
resource, and the resource server able to authenticate that particular user,
if not the best is create a account in resource server, specify the user
credential at the UNC path configuration.
Opne IIS MMC, F1- look for UNC authentication.
