Endpoint Protection

I have a customer who have a server provided my the manufacturer of the product they sell. I have very little access to the domain, server and the configuration. I can add users and workstations.  When the users login, they have a login script that pops up says 'press any key to continue'. once you press a key, it maps some drive letters and does some other tasks, (like updates, when required).  Everything worked fine under Symantec Corp 10. I have a workstation as the server for the AV.
 
When I upgraded them from 10.2 to SEP11, a new problem occurred.  The login script runs, prompts them to press any key, as it always did. Some component of symantec must run afterwards, causing the login script window to lose focus. Users must click on the window before they press any key to continue.  It's an extra step that some find annoying. Some users believe there is a problem because it doesn't continue after they press a key, and were pressing the reset button to restart the computer. I'm not sure how to correct this. I have administrative rights on the workstations. Is there a registry entry I can modify so that the login script keeps the focus?

I am not sure if this is exactly what you are looking for but you should check out a program called TweakUI. I have used this on multiple occassions for helping me keep certain windows in focus, but this is allways AFTER login so I don't know if Tweak UI has some command line option that you can run at the same time as your install script. Might be worth trying. Also after some googling I found a post on a cite that says that on vista this reg key can be altered:

[HKEY_CURRENT_USER\ControlPanel\Desktop]
ForegroundLockTimeout

So that might be something else to try and play with. You should always back up your registry before doing these kinds of changes. Also what language are you using to write the script? You might also just be able to have a delay in the script that keeps it from coming up until AFTER SEP is done doing everything.

Hope this helps,
Grant
