"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

'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.
