Core FTP

I tried putting the name of the domain controller in the domain box, and still cannot logon. On the client I tried the username by itself, domain\username, domaincontrollerservername\username, same problem login failure

I want to use the domain users, and I currently have the domain name in the box, should I be using the server name of the domain controller ? I'll try that in the mean time.

I can't get NT Authentication to work. I specify my domain in the domain box. I am using mydomain\myuser as the login user ? Does Core require a different syntax ? Creating users manually works fine.
