[H] Windows 8 and Home Server (not 2011)

[Thane Sherrington]

Here's an odd one.  I have a client with Windows 8 Pro 64 bit 
connecting to a Home Server (not 2011).  It thinks that there is 
1.91TB free of 1.34TB (more free than there is total space) so it 
keeps saying the drive is full even though it isn't.

Does anyone know how to convince Windows 8 that the drive isn't full? :)
