Yes, I was trying to intercept user's logon. I've done it using userinit 
registry key, a python NT service and a python service running on the PDC.

My problem is also that the service has to be available at logon time to 
do some administrative stuff.

It seems that the policy "gpedit" > Computer 
Configuration\Administrative Templates\System\Logon\ "Always wait for 
the network at computer startup and logon" (registry key
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows 
NT\CurrentVersion\Winlogon : SyncForegroundPolicy=1) can help me.

Putting a loop to wait the service is up can also be a good idea.
