<h3>Database migrated!</h3>
You need to do the following to complete the process:
<ul>
	<li>Install the <b>@@zonepath</b> zone file into your bind install, and restart bind
	<li>Change your smb.conf to set "server role = domain controller"
	<li>Shutdown your existing PDC and any other DCs
	<li>Restart smbd
</ul>
