if you’re trying with Anonymous user, please make sure that IUSR ID should add to the remote folder permission then its works (this is not possible)
Try this one in App pool setting under Network Services replace with domain user or local user and add same user to folder permission.
Also Make sure that the user who is logged on to the Web server has sufficient NTFS permissions on the remote share and has the "Access this computer from the Network" user right on the computer that has the remote share.
