This article provides a resolution for the issue that you can't turn on Network Discovery in Network and Sharing Center.

Applies to:   Windows Server 2012 R2
Original KB number:   2722035

Symptoms

You try to turn on Network Discovery on a computer that's running Windows Server 2012. To do it, you change the Advanced sharing settings in Network and Sharing Center. However, the changes aren't saved. So you can't turn on Network Discovery. And you experience the following issues:

• You can't browse or find any network share.
• You can't view shared folders on a local network.

Cause

This issue occurs for one of the following reasons:

• The dependency services for Network Discovery aren't running.
• The Windows firewall or other firewalls don't allow Network Discovery.

Resolution

To resolve the issue, follow these steps:

1. Make sure that the following dependency services are started:

   • DNS Client
   • Function Discovery Resource Publication
   • SSDP Discovery
   • UPnP Device Host

2. Configure the Windows firewall to allow Network Discovery by following these steps:

   1. Open Control Panel, select System and Security, and then select Windows Firewall.
   2. In the left pane, select Allow an app or feature through Windows Firewall.
   3. Select Change settings. If you're prompted for an administrator password or confirmation, enter the password or provide confirmation.
   4. Select Network discovery, and then select OK.

3. Configure other firewalls in the network to allow Network Discovery.

4. Turn on Network Discovery in Network and Sharing Center.

• Question

• Good afternoon.

  As per the title, I have set-up a new server at work. The server is running no problem but none of the other computers connected to the network can 'see' the new server. I've gone into the control panel and tried to turn on the network discovery, but it just defaults back to 'off'.

  I did so a search on here first before troubling anyone and I did find this answer :

  "

  Thanks for the post.

  I did some research and found this issue may occur if the dependency services are disabled. Please make sure the following services are enabled and running.

  - SSDP Discovery

  - UPnP Device Host

  Disabling Network Discovery/Network Resources"

  That may well be the answer, but unfortunately that means absolutely nothing to me.

  Is someone able to help me try and switch this on, but by offering an explanation an 'idiot' would understand.

  Thanks in advance.
