------------------------


It is not possible to start a windows gui job on windows vista hosts without having a user logged in.

When a job is submitted to a vista host where no user is logged in the following error is logged into
the execd messages file:

06/30/2009 15:26:19|  main|host|E|06/30/2009 15:26:19 [1049715:3121]: Getting Logged On User Token failed: Only part of a ReadProcessMemory
or WriteProcessMemory request was completed. (errno=299)


The job was submitted with following command line:
> qsub -l h=host,display_win_gui=true -b yes -shell no /dev/fs/C/WINDOWS/notepad.exe
Your job 7 ("notepad.exe") has been submitted

The job goes into error state when he is dispatched to the host:

Evaluation:

The vista job start code on the helper service differs from the standard implementation.
The problem is that the function GetInteractiveUserToken() can not get the a session token when no user is logged in.

How to Fix:
a) Find out how to startup GUI jobs when no user is logged into the vista host
b) Add a load report consumable which reports if it is possible to startup a windows GUI job on this host and
   request e.g. WGUISupport=true when a job is submitted.

Workaround:
A user must be logged into the windows vista system.
The GUI job also starts up correctly when the screen is logged.
