Yes, once I map the folder as F: drive, it does show as F: drive in Windows Explorer.
It is also important to mention, using the Command Window, I can issue F: enter
and it does to F: drive.

No, running it as Admin did not make a difference. It still does not recognize any of mapped drives.

Thank you for your comments.
