"ERROR_NONE_MAPPED" 1332

that is slow.. too slow to use on our servers in the application.
cName = space(100)
GetUserNameEx(1, @cName, 100) should work, but returns an error.
GetLastError() = 1332.

GetUserNameEx(2,@cname,100) is the only one that works, but that returns the login name, not the full name.
