It's usually a bad idea for a service to open a user's desktop, but I'm not sure about a winlogon desktop.
Anyway, if you're a service then you're running in session 0, and the winlogon desktop is running in some other session. Are you sure that you opened the console session before looking for a winlogon desktop?

Hi everybody,
Now I'm writing a software which interacts with winlogon Desktop of Vista. I
want to control winlogon desktop such as show a message box, draw a icon on
winlogon desktop...
But when I opendesktop(), I always meet a message: "Access is denied."
hDesktop = OpenDesktop(
TEXT("Winlogon"),
0,
FALSE,
DESKTOP_CREATEMENU |
DESKTOP_CREATEWINDOW |
DESKTOP_ENUMERATE |
DESKTOP_HOOKCONTROL |
DESKTOP_JOURNALPLAYBACK |
DESKTOP_JOURNALRECORD |
DESKTOP_READOBJECTS |
DESKTOP_SWITCHDESKTOP |
DESKTOP_WRITEOBJECTS |
READ_CONTROL |
WRITE_DAC |
WRITE_OWNER );
I make a windows service to run my program when logon. I don't know why it
show error "Access is denied."
If you know that, please show me. Thank you very much
.
