SetDNSDomain, Invalid Method Parameter error

Disregard, I found how to do this correctly...

I also ran into an issue because the network cable was disconnected. The
call returned an "IP not enabled" error. Seems that you should be able to
set this without a cable connected...

I have the following code. SetDNSDomain is a per-adapter setting but I am
doing something wrong because I am getting an "Invalid Method Parameter"
error on ExecMethod. Everything works okay until the ExecMethod. I am not
sure that I pointing to the adapter vs. the class when I am making the call.
Is there an example of how to make a change to a unique device returned from
a query? Thanks.
