Retrieving session ID

Retrieving session ID

Retrieving session ID

(OP)
Hi,

I'm trying to retrieve the session ID of a process. More specifically, a printer driver process; and the session ID I need is the one in which the user who submitted the print job is working.

In Windows XP, I use the user's security token to let SYSTEM impersonate as that user, call GetCurrentProcessId and convert the process ID to a session ID using ProcessIdToSessionId.

My problem lies with Vindows Vista: here, the driver runs as user LOCAL SERVICE and ProcessIdToSessionId fails with error 5, E_ACCESSDENIED.

Does anyone know how I can get the process to session ID conversion working in Vista?

If you need more information about what I'm trying to do, please ask.

Regards,
Bert Vingerhoets
