As for rebooting you can utilize the <b>schtasks</b> command through their login script like this:<br />

<blockquote>
schtasks /create /ru &lt;administrator&gt; /rp &lt;password&gt; /sc dialy /st 23:59:00 /tn shutdown /tr &quot;shutdown /t 0 /r&quot;
</blockquote>
But that will require you to put a password in the login script unless the users have admin rights on their workstation.<br />
<br />
Alternatively you can create a schedule on your server that reboots all workstations on the LAN by using the tsshutdn or shutdown command (depending on your server version). &nbsp;Just export all your workstations from ADUC into a text file and prepend the shutdown command to each line.
