How enable stealth mode on port 445?

Question

I run Shields Up on grc.com and find all ports are stealth but 445 that is closed.

I'd like to turn port 445 from closed to stealth.

How?

I've searched a lot on firewall settings but I didn't find anything.

Running Microsoft Windows [Version 10.0.19043.1415]

Thanks.

Answer 1

This might help you add a firewall rule to port 445.

-Go to Computer Configuration > Policies > Windows Settings > Security Settings > Windows Firewall with Advanced Security > Windows Firewall with Advanced Security - LDAP > Inbound Rules.
-Right-click and choose New Rule.
-Choose Port and click Next.
-Choose TCP and at specific local ports enter 445, then click Next.
-Select Do not Allow the connection and click Next.
-Choose Domain (or other, depending on your knowledge), then click Next.
-Specify Radar Scanning as the name and click Finish.

Hope this resolves your Query!!

I did what you wrote but the 445 port remain "closed" (blue colour means closed, green means stealth).
As you may see in the attached screenshot .
