Do you have a problem with user logon scripts not running on Vista? As far as I read te messages on this board, this problem only appears if
  • The user login on has Local Admin rights (per example Domain Admin)
  • User Account Control is switched on

Is this what you are looking for: After you turn on User Account Control in Windows Vista, programs may be unable to access some network locations?
If yes, please let us know. Maybe it can be put in Q&A on this board?
