I just upgraded my computer from Windows 7 Ultimate to Win 10 Pro. After the process all my network drives have been disconnected and no longer appear under Network along with the other computers connected to the network. I have checked my Network sharing and discovery settings, and I can see the Win10 computer from other computers on the network, just not the other way around.
I followed the instruction given here: Windows 10 computer can't connect to any other computer on the network however this did not solve my problem.
I am connected to the network via Ethernet, and was before as well.

If the network drives appear disconnected
Try opening them anyway; the disconnectedness is checked at login time, a time at which network connections may or may not be fully established. If you get a prompt for credentials, enter them; it's possible saved passwords got lost in the upgrade.
If the network drives disappeared
Recreate them. It's possible that they got lost in the upgrade; they should stay put after being made in Windows 10.
If you can't see other computers on the network
You probably need to enable network discovery and file sharing.
Open the desktop Control Panel (it's on the Win+X menu). If you're in Category view, choose View network status and tasks. If you're in one of the icon views, choose Network and Sharing Center. Then, on the left, click Change advanced sharing settings.
Expand Private or Guest or Public depending on what you've called your current network connection. (Private, hopefully.) Make sure Turn on network discovery and Turn on file and printer sharing are enabled, then press Save changes.
