Powershell Get-ChildItem fails with ‘Access is denied’ as a remote call

I’m trying to query the files on the remote machine using the following syntax, it fails with access is denied / permission denied. Am I missing something,

The permissions on the target are given with full control and to all folder, subfolders and files. Permissions are given at Y: volume level.

Get-ChildItem \serverAY$folderA
