Revision 2. </p> <p>This script (or exe if using web2py with """setup(windows=['locker2.py']))""") can be run as a task in windows every x minutes and will test for the presence of an internet connection and depending on whether it is found will set windows to lock after a given timeout without user activity.</p> <p>This was made with help from random code snippets from around the web.</p> <p>Tested only on windows 7.</p>

For example, we use these to lock system-wide log files that multiple processes can write to.</p>
