Dude 3.6 Name to Address not working

Good afternoon,

I have installed dude 3.6 on a Windows 10 computer simply to probe a port to see if a client is online. I am using 3.6 as i want it to work standalone without a server.

On my home computer Windows 10 resolving name to address works fine and i can add new devices.

When i install it at my office computer with Windows 10 again it doesn’t work it just won’t resolve the addresses.

Has anyone else faced this problem?
