domain name system - How to ping a server on a different network by the hostname only?

have two networks that I am connected to via my computer, two different routers and all. This computer is connected to a windows domain "Domain A", I can resolve the IP from any Computer Name from CMD/Ping on the same Domain A network. But on a different NIC on the same computer, I can't resolve Domain B computers just by the host name alone, I need the FQDN (like machinename1.domain.local) when pinging Domain B computers. How can I suppress the fact that I need the FQDN?

Hope this makes sense, this is the only way that I know of how to ask this question.

Answer

Add the name of Domain B to your DNS Suffix Search List. Either manually through IPv4 settings -> Advanced -> DNS, or automatically through Group Policy.
