Using Copy-Item to overwrite files in remote server directory

Question

Hello,
I am trying to copy newer files over older files from my workstation to a server using the copy-item cmdlet.
The cmdlet looks something like this:
copy-item *.* \\servername\c:$\pathname -force
There are no subfolders involved, so -recurse is not necessary.
When I run the command, I get this:
Copy-Item : Access to the path <Destination> is denied.
At line:1 char:1
+ Copy-Item '<source file>' '<Destination>
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [Copy-Item], UnauthorizedAccessException
    + FullyQualifiedErrorId : System.UnauthorizedAccessException,Microsoft.PowerShell.Commands.CopyItemCommand
I am running with administrative credentials at both ends of the network path AND I can use the GUI to copy and paste the files using Windows Explorer.  I am losing hair due to scratching my head.

Answer 1

Yes, what threw me was my ablity to copy and paste using Explorer from my machine to the server in an RDP session. I asked myself, "If I could do that, why can I not use the command line?"
Then I did some googling and found all kinds of the same error but it was pointing towards files that existed or sharepoint sites.  In some of those cases, the solution was to remove the folder and then replace it.  That was not a an option in
my case.
So, I figure I can read using my normal user credentials and copy to the clipboard and then in the RDP window, I am the Admin user and can paste from my machine's clipboard.  Interesting behavior.
