How to unblock WMI and Remote Administration port in my SEP client ?

Hi All,

The entire server and workstations in my company is now managed by Symantec Endpoint client v12.1.6, however when I try to run my powershell query to get server service status, I get:

The RPC server is unavailable. (Exception from HRESULT: 0x800706BA)

Windows 2008 R2

Start | Control Panel | System and Security | Windows Firewall then select “Allow a program or feature through Windows Firewall”.  Scroll down and click on check box next to “Windows Management Instrumentation (WMI)” which should automatically select the check box in the Domain column.  Click OK.

Windows 2012 and Windows 2012 R2

Open Server manager (open by default) and click on Local Server on the left side of the screen.  In the Properties box, click on setting to the right of the label Windows Firewall (Domain: On). You can also get to the Windows Firewall setting by selecting Control Panel | System and Security | Windows Firewall

Select “Allow an app or feature through Windows Firewall”.  Scroll down and click on check box next to “Windows Management Instrumentation (WMI)” which should automatically select the check box in the Domain column.  Click OK.

So I wonder what's the best way to open up this port since it seems that it is blocked by default.

Thanks,
