Hi,
Are you admin user?
Method 1:
To resolve the problem,
1. Click Start – Search, type “Services.msc”
2. Look for Function Discovery Resource Publication, right-click and select properties.
3. Set the service to start as “Automatic (Delayed)” as against the default “Automatic”
Method 2:
However, you may verify if the following services are started and set to automatic in services window.
To do this, follow the steps below:
- Click on Start
- Select Run, type "services.msc" and check if these services are enabled:
- TCP/IP NetBIOS Helper service
- DNS Client
- Function Discovery Resource Publication
- SSDP Discovery
- UPnP Device Host
To start the service and set it to automatic, follow the steps below:
- Right-click one of the services listed above and click on Properties.
- Click the General tab, and then, next to Startup type, select Automatic.
- Click Apply, and then click Start.
If the above steps do not help, create a new user account and check if you can turn on Network discovery.
To create a new user account follows the steps below:
- Open User Accounts by clicking the Start button, clicking Control Panel, clicking User Accounts and Family Safety (or clicking User Accounts, if you are connected to a network domain), and then clicking User Accounts.
- Click Manage another account. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
- Click Create a new account.
- Type the name you want to give the user account, click an account type as Administrator, and then click Create Account.
If you are able to turn on network discovery using the new profile, access the link below and follow the steps to fix the user profile.

I would also suggest you to enable network discovery and check.
