This is standart Windows10 firewall. No specific application.
In the firewall, the permission for DrServer.exe for TCP and UDP protocol is registered separately. I have asked my admins for details, because they did it and helped to me.
Yes, it works now without "Search lan" option.
Admin created these two new rules for input connection for DR server.
In the top-left corner automatically created rule by installer, I thought. We leaved it.
