Rod,
Welcome to the board. There is a GPO setting for RunLogonScriptsSync that will make your script visible and hold the desktop until the script completes. Alternatively you could hack it into the reg but if you're running AD and GPOs then why bother. Once your scripts run sync, you can influence the console with the SetConsole() function. Options are:
SHOW - Show window
HIDE - Hide window
FOREGROUND - Move window to foreground
ALWAYSONTOP - Bring window to top
MINIMIZE - Minimize window
MAXIMIZE - Maximize window

For the AD GPO script, check out this thread
