Connected client without domain...can't see server folders

Hello all - I have a Windows 7 client that I connected to Server Essentials 2012 without joining the domain. I used the reg key below before running the connector:

reg add "HKLM\SOFTWARE\Microsoft\Windows Server\ClientDeployment" /v SkipDomainJoin /t REG_DWORD /d 1

Everything seems to have worked fine except for one item - I cannot navigate to the server via "My Computer". If I click on "Shared Folders" within the launchpad, I can access the folders fine. But if I try accessing via My Computer, the server is "invisible".

Any suggestions?
