Actually I use winlogon notification
http://www.codeproject.com/KB/system/winlogon_notification_package.aspx
to launch an app that reads a configuration file on a samba PDC server
and write some registry keys.
The configuration file depends on :
- user name or group
- machine name (there's a concept of machine group based on machine names)
thus configuration file can be
\\<pdc>\netlogon\<machine_group>\<user_name_or_grp>.xml
With graphical app that contains a database of registry keys and
descriptions about them ("User cannot access printer configuration",
"Hide checked drivers from My Computer" etc.).
So at logon, the program rewrites also the Desktop, Start Menu, ... and
AppData paths. This is done before explorer starts (eventually kill and
restart it if it runs). But in a command line prompt "cmd" 'echo
%appdata%' doesn't return the path written in the registry. And I've
noticed that some application gets AppdData path from something like
"os.environ['APPDATA']".
What can I do to solve this ?
