Consider the following scenario:

• In the Active Directory domain environment, you create the Predefined Windows Firewall outgoing and incoming rules for File and Printer Sharing and Network Discovery.
• You select Allow the connection for the Firewall outgoing and incoming rules.
• The Firewall rules are applied to the client computer.

In this scenario, you encounter the following issues on a client computer that is running Windows Vista or Windows Server 2008:

Issue 1
In Network and Sharing Center, you see that Network discovery and File sharing are turned off.

Issue 2
When you click View computers and devices, you do not see any computers in Network Explorer. Additionally, you receive the following message in the information bar of Network Explorer:

This problem occurs because Network Explorer, and Network and Sharing Center check the local firewall policy. However, they do not check whether the domain firewall policy is configured. Even though the domain policy is configured to enable network discovery, or file sharing, Network and Sharing Center show that these settings are disabled. Therefore, Network Explorer does not let the user browse the network. This occurs because of a conflict between the local Firewall policy and the domain Firewall policy.

To resolve this problem, install the following hotfix on the client computer. This hotfix enables Network and Sharing Center, and Network Explorer to check the local Firewall policy, and the domain Firewall policy to determine whether Network discovery or File sharing is enabled.

Note The Domain policy takes effect without this hotfix. This hotfix only changes the display in Network and Sharing Center, and Network Explorer.
