Cannot access Network Shares on Windows 8

I had an instance where I had a Windows 8 laptop with a local Administrator but when I tried to browse to the C$ share I was displayed the error "multiple connections are not allowed"  from command line I got an Access Denied message.  All this was even though I was using the right credentials.

It turns out to be a UAC filtering policy in Windows 8 that blocks access unless you use Remote Desktop to the OS.

The solution is in this Microsoft KB article http://support.microsoft.com/kb/951016

A big thanks to Helge Klein for this one.
