RDP over VPN can't see a .git directory to be able to pull

I'm trying to 'git pull' between two W10 systems over a VPN with RDP.

I map my local C:\ drive to drive s:\ on the remote system so on the remote
system, I can see my local C:\ drive that has the repository
On the remote system, I do
     git pull s:\gitrepository
but it says
     ...does not appear to be a git repository, could not read from 
remote repository

In a command line window on the remote system, I do
     dir s:\gitrepository
and the .git directory is not shown in the listing. All the other files are
including the .gitignore file (has a dot at the start).

But I can do
     dir s:\gitrepository\.git
and all the files and subfolders under .git are there.

I've set the "Show hidden files, folders, and drives" radio button in the Folder Options | View window if that matters.

Any idea why the .git directory is being blocked from being seen unless specifically specified, but I can see the .gitignore file just fine?
