We are using win2k with metaframe 1.8 sp2, a few of our users are leaving there machine idle for about 5 minutes and coming back to them to find a dialog box saying "this computer has been locked and only an administrator or user\john1 can unlock it" please put your password in. This also happens to me when i leave my machine idle for about an hour. any ideas where the setting for this idle time is or how to change it. [sig][/sig]
