CreateProcessAsUser fails in windows XP (from remote desktop - session 1)

So whether it is ok,
if i use session 0 to run an exe,
using a process, which is running in session 1 ?

I have used below code (winlogonPid is from session 0)

hProcess = OpenProcess(MAXIMUM_ALLOWED, False, winlogonPid)
OpenProcessToken(hProcess, TOKEN_DUPLICATE, hPToken) 

then use DuplicateTokenEx and CreateProcessAsUser

Thanks.
