I set up a Homegroup 2 nights ago, was very please that it is not too difficult and it worked great

I was able to connect to my desktop from the laptop, use all functions and programs and view the desktop to access the complete computer.
The next evening when I logged in my access was limited to docs and pictures only.
I been trying to access the entire desktop again for the last 2 days with no luck, does anyone know what this issue could be? Trying to get full function back if you can help. Thanks!
