Manual

An additional firewall rule is needed to enable a remote user to establish a WMI session. It can be
enabled with the following command:
netsh advfirewall firewall set rule name="Network Discovery (NB-Name-In)" new enable=yes
This command updates a portion of a rule group (a single rule). It can also be done in the user
interface, using the following procedure:
1. Click Administrative Tools > Windows Firewall with Advanced Security > Inbound Rules.
2. Enable the Network Discovery (NB-Name-In) rules.
3. Select the rule, and then click Action > Enable Rule.
This rule and its equivalent rule appear in the Network Discovery and the File and Printer Sharing
firewall rule groups, respectively.
If the Windows® Firewall has either of these already enabled, the latter command does not affect a
change, and only first command is necessary.
Similar rules can be created that are more restrictive but that enable remote WMI access in specific
circumstances (such as restricting which users, computers, and network addresses can remotely access),
depending on your setup.
There can be additional configuration and connection requirements on the client-side depending on
the client operating system and firewall used.
