'In order fot that to work, you need to be logged on with an username/password combination that also exists on the remote computer - in other words, if you are signed on as "JohnDoe" with the password "TopSecret", the other machine also needs to have an account "JohnDoe" with the PW "TopSecret". BTW, the machine name needs to be prepended with two backslashes, i.e.

LookupAccountName(L"\\\\machine_name", L"machine_name\\JohnDoe",...);

You don't need to, the NTLM subsystem will take care of that - yet the aforementioned precondition applies.
