Within the options of the network - TCP/IP options you have to tick boxes under advance - DNS
The first is "Register this connection's addresses in DNS"
The second is "Use this connection's DNS suffix in DNS registration"
I can find articles on how to enable or disable the first option, however I can't find anything regarding the second one.
I want to find out which registry key affects the second so I can change it either through a script or with custom registry entries in group policy
