Cannot connect to network

I just attached an ethernet cable to my WD TV Live.  Internet works but everytime I try to access my files on the computer it gives me the error message " The device could not connect to the network"  

Network is HOME NETWORK

Firmware version is 1.04.17

OS - Windows 7

I have turned on sharing for the folders that I want

I have set the Advanced Sharing Options as follows:

Network Discovery - ON

File and Printer sharing - ON

Public Folders - OFF

Media Streaming - OFF

128 bit encryption - ON

Password Protected - OFF

I am not sure what else to do.

“Network is HOME NETWORK”

Is that your Workgroup name?  If so,

Just for giggles, try renaming your workgroup name to something WITHOUT a space in it.

Don’t forget to change both the PC and the WDTV.    Don’t change anything else in the meantime.

Let me know if that fixes it.
