Hi.

I'm having a very strange behavior - CreateProcessAsUser fails with error 233 when called from service while logon screen active. Service

tries to create a process when new console session connected, so when it receives the SERVICE_CONTROL_SESSIONCHANGE notofication with the WTS_CONSOLE_CONNECT, it obtains a user token (via WTSQueryUserToken or

OpenProcessToken/DuplicateTokenEx/SetTokenInformation - no sense). In

most cases it works well, but when it create a process after user

logoff (and now system in logon screen) it fails with error 233.

How to reproduce it:

1. Logon as console user (session 0)

2. Switch user (logon screen, session 0)

3. Logon another user (session 1) (CreateProcessAsUser succeeded)

4. Logoff another user (logon screen, session 2) (CreateProcessAsUser

fails, 233)

In my sample i'm trying to launch calc.exe, and in vista it works

well, problem appears only with the Windows XP.

Anyone else seen a similar issue, or know why this is happening? If it

helps, i can upload a sample to reproduce this behavior...

Thanks.

I am having the same issue with CreateProcessAsUser at the logon screen (this is to run a vnc server w/o any UI). WTSQueryUserToken returns a NULL token and CPAU fails. Any help?
