So here's how you solve it:
1. Disconnect the previously mapped network drive from Windows Explorer.
2. Right click on Command Prompt in the Start Menu and selected Run As Administrator.
3. Typ "Net Use y: \servernamesharename"
4. Exit out of the command prompt
5. Open Windows Explorer
6. Click 'Map network drive' menu item
7. Select the y: drive and typed \servernamesharename into the Folder box.

Not very intuitive, but it works!

EASIER WAY: If you already have a mapped network drive, just do steps 2-4 and it should work...essentially you map it once for the user, once for the administrator. (can't we all just share stuff and get along?)
