Pythin createprocessasuser -- OpenProcessToken, 'Access is denied.'

[Pete Fong]

Dear all,

I am a beginner with Python. I want to write a program as "runas" in
Windows XP.
But I have got the following error:
File "C:\Python23\Lib\site-packages\Pythonwin\pywin\framework\scriptutils.py",
line 310, in RunScript
    exec codeObject in __main__.__dict__
  File "C:\python\Script1.py", line 30, in ?
  File "C:\python\Script1.py", line 14, in AdjustPrivilege
    print "Started as: ", win32api.GetUserName()
error: (5, 'OpenProcessToken', 'Access is denied.')

There is my program :

import win32security
import win32process
import win32api
import win32con
import sys
import time
import os
from ntsecuritycon import *


def AdjustPrivilege(priv, enable = 1):
    # Get the process token.
    flags = TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY
    htoken = win32security.OpenProcessToken(win32api.GetCurrentProcess(),
flags)
    # Get the ID for the privilege.
    id = win32security.LookupPrivilegeValue(None, priv)
    # Now obtain the privilege for this process.
    # Create a list of the privileges to be added.
    if enable:
        newPrivileges = [(id, SE_PRIVILEGE_ENABLED)]
    else:
        newPrivileges = [(id, 0)]
        win32security.AdjustTokenPrivileges(handel, 0, newPrivileges)
    # and make the adjustment.
    

handel=win32security.LogonUser('administrator','domain','pwd',win32con.LOGON32_LOGON_INTERACTIVE,win32con.LOGON32_PROVIDER_DEFAULT)

win32security.ImpersonateLoggedOnUser(handel)
AdjustPrivilege(SE_TCB_NAME)
AdjustPrivilege(SE_INCREASE_QUOTA_NAME)
AdjustPrivilege(SE_ASSIGNPRIMARYTOKEN_NAME)
AdjustPrivilege(TOKEN_DUPLICATE)
AdjustPrivilege(TOKEN_IMPERSONATE)
AdjustPrivilege(SE_CHANGE_NOTIFY_NAME) 



print "Started as: ", win32api.GetUserName()
#this prints target username, impersonation successful  

win32process.CreateProcessAsUser(handel,None,'notepad',None,None,0,0,None,None,win32process.STARTUPINFO())
#os.execv('c:', 'notepad')
#os.execv(path, args)
#runs program, not as target user 


win32security.RevertToSelf()
handel.Close()


Could anyone help me ? What's wrong ? Thanks a lot ?

Best Regards,
