I have a strange issue on a laptop, and was wondering has anyone come accross this issue. We have a Dell D600 laptop, win xp pro and running version 5.1.8.
When the laptop locks as per screensaver settings, the only person that can unlock the laptop is the person logged in, all atempts by admininstrators and other users with permissions to the user group, to unlock the laptop get error "Token authentication parpamiters are incorrect" If the option single sign on to windows is enabled it reports too many incorrect logins and locks out for 60 secs initially and further atempts for longer.
All admins have lvl3 access and are in the users group for all laptops, they are therefore able to unlock the screensaver, but not on this machine. it seems to be the only machine it is happening on but we are mid roll at the moment and if the problem occurs again we need to know how to resolve it.
