Windows 10 is finicky with WHS.
Recently Microsoft updated their current OS's to a more secure network file transfer protocal, SMB 2.0 + 3.0. WHS only uses version 1.0. There are security risks in turning on this feature, especially with laptop's that connect to other networks. So
proceed at your own risk.
In Windows 10, if you open up Settings > Search "Windows Features" the result will bring up "Turn Window's Features on or off"
This will bring up the window with the list of items you can turn on or off. Scroll down to SMB 1.0/CIFS File Share Support and check the box. Click OK
IT will install that feature, and you'll need to restart your computer. Once you are back up, try connecting again. this solved about 99% of the issues I was having with Windows 10 and WHS talking to each other.
Best of luck!
